The equation of the line is y=5x+17.
What is slope intercept form of the equation?
When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b). It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.
Here the given the point [tex](x_1,y_1)=(-4,-3)[/tex] and slope m = 5.
Now using equation formula then,
=> [tex]y-y_1=m(x-x_1)[/tex]
=> y -(-3)=5(x-(-4))
=> y+3 = 5(x+4)
=> y+3 = 5x+20
=> y = 5x+20-3
=> y = 5x+17
Hence the slope intercept form of the equation is y = 5x+17.

Answer:
D) a trapezoid with congruent diagnols
Explanation:
When none of the sides of a trapezoid are congruent, then it is a non isosceles trapezoid or a scalene trapezoid.
suppose that one customer who participated in the study is chosen at random. what is the probability that the customer did not have a high level of satisfaction with the company?
Answer: Without additional information about the study and the definition of "high level of satisfaction," we cannot determine the probability that a randomly chosen customer did not have a high level of satisfaction with the company.
The probability would depend on the specific criteria used to define a high level of satisfaction, as well as the distribution of satisfaction levels among the customers in the study.
If we have access to this information, we could use it to calculate the probability that a randomly chosen customer did not have a high level of satisfaction using the appropriate formulas or statistical techniques.

identify the values of a, h, and k in the given function, and choose the correct transformation.
The correct transformation is - "a is a stretch by a factor of 5, while h moves the graph to the left by 6, and k moves the graph up by 7".
Explain about the algebraic transformation:A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location. Every point in a reflection is equally spaced from a fixed line
The line of symmetry is another name for this curve. The Image and Pre-Image share the same size in a reflection.
General form for the member of the reciprocal family:
y = a /(x - h) + k ..eq 1
For the given function:
y = 5/(x + 6) + 7 ...eq 2
On comparing eq 1 and eq 2
a = 5
h = -6
k = 7
Now,
As, -6 is added to the x value, it shows the shift to left on x axis.5 is multiplied with the value of x, which represents the stretch with factor.At last 7 is added to the function, shows that there is a upward shift by unit 7.Thus, the correct transformation is - "a is a stretch factor of 5, while h moves the graph to the left by 6, and k moves the graph up by 7".

if you use the normal distribution to estimate the probability that score exceeds 100, would the answer be zero? why does your answer contradict the assumption of a normal distribution for score?
If you use the normal distribution to estimate the probability that score exceeds 100, the answer would be zero.
This is because a normal distribution is a continuous probability distribution, and the probability of any individual score, no matter how high or low, is always zero.
However, this answer contradicts the assumption of a normal distribution for scores because it implies that scores cannot exceed 100, which is not true. Scores can theoretically range from negative infinity to positive infinity, and in practice, there may be some scores above 100, especially if the measurement instrument is imprecise or the test is very difficult.
Therefore, if we observe scores that are higher than 100, it suggests that the assumption of a normal distribution may not be appropriate for the data, and we may need to use a different distribution or statistical model to estimate probabilities or make inferences about the scores.

Using your calculator, graph these functions and find the solution to the system.
f(x)= x^2 + x - 6
g(x)= -2x^2 - 2x + 12
1- (-3, 0) and (2, 0)
2- (0, -6) and (0, 12)
3- No solution: They do not intersect.
4- (-6, 12)
The solutions to the system of equations f(x) = x² + x - 6 and g(x) = -2x² - 2x + 12 are (-3, 0) and (2, 0). So, correct option is 1.
To graph the functions f(x) and g(x) using a calculator, we can enter the equations into the calculator's graphing function and choose an appropriate window to display the graph. Once the graphs are displayed, we can look for the points of intersection to find the solution to the system of equations.
Using a graphing calculator, we can see that the graphs of f(x) and g(x) intersect at two points: (-3, 0) and (2, 0). These points represent the x-coordinates of the solutions to the system of equations.
To verify that these points are indeed the solutions, we can substitute each of them into both equations and check that they satisfy both equations simultaneously.
For point (-3, 0):
f(-3) = (-3)² + (-3) - 6 = 0
g(-3) = -2(-3)² - 2(-3) + 12 = 0
Therefore, (-3, 0) is a solution to the system of equations.
For point (2, 0):
f(2) = 2² + 2 - 6 = 0
g(2) = -2(2)² - 2(2) + 12 = 0
Therefore, (2, 0) is also a solution to the system of equations.
The point (0, -6) and (0, 12) are not the points of intersection and (-6, 12) is not a solution to the system of equations.
Therefore, the answer is option 1.

a shop is open 9 am - 7 pm. the function r(t), graphed above, gives the rate at which customers arrive (in people/hour) at time t, where t measures time in hours since 9 am. suppose that the salespeople can serve customers at a rate of 75 people per hour. answer the following questions: d. when does the line vanish? answer: equation editorequation editor hours after opening.
A shop is open 9 am - 7 pm. the function r(t), graphed above, gives the rate at which customers arrive (in people/hour) at time t, the line will vanish at 9 am + 2.5 hours = 11:30 am.
Since the salespeople can serve customers at a rate of 75 people per hour, the net rate at which customers are added to the line is given by:
Net rate = R(t) - 75
where R(t) is the rate at which customers arrive.
The line will vanish when the net rate becomes zero, which means that the rate at which customers are added to the line is equal to the rate at which they are served. Thus, we have:
R(t) - 75 = 0
Solving for t, we get:
R(t) = 75
Looking at the graph, we can see that R(t) is equal to 75 at approximately 2.5 hours after 9 am. Therefore, the line will vanish at 9 am + 2.5 hours = 11:30 am.

Julia and her husband own a coffee shop. They experimented with mixing a City Roast Columbian coffee that cost $7. 80 per pound with French Roast Columbian coffee that cost $8. 10 per pound to make a 20-pound blend. Their blend should cost them $7. 92 per pound. How many pounds of each type of coffee should they buy?
They should mix 16 pounds of City Roast Columbian coffee with 4 pounds of French Roast Columbian coffee to make their blend.
How many pounds of each coffee should be used?Let x be the number of pounds of City Roast Columbian coffee.
Let y be the number of pounds of French Roast Columbian coffee.
The total cost of the blend is 7.80x + 8.10y
The total weight is x + y = 20.
We can write an equation for the cost per pound:
(7.80x + 8.10y) / 20 = 7.86.
We will multiply both sides by 20 which gives:
7.80x + 8.10y = 157.20.
We can use this equation along with the total weight equation to solve for x and y:
x + y = 20
y = 20 - x (subtract x from both sides)
7.80x + 8.10(20 - x) = 157.20 (substitute y = 20 - x into the cost equation)
7.80x + 162 - 8.10x = 157.20 (distribute)
-0.30x = -4.80
x = 16
Solve for the equation (x + y = 20):
y = 20 - x
y = 20 - 16

What is trigonometry?The links between triangle's sides and angles are studied in the mathematic discipline known as trigonometry. It entails an examination of triangle's angles, lengths, and areas as well as their angles' mathematical properties (such as sine, cosine, and tangent).
According to question:The situation described can be modeled as a right triangle, where the wire from the electric box to the pole is the hypotenuse, and the angle of elevation is one of the acute angles. Let x be the length of the wire needed in feet.
Using trigonometry, we can write:
sin(17°) = opposite / hypotenuse
where the opposite side is the height of the connection on the pole above the ground. We can solve for the hypotenuse (the length of wire needed) as follows:
hypotenuse = opposite / sin(17°)
To find the opposite side, we can use the fact that the angle of elevation is 17° and the distance from the pole to the point on the ground directly beneath the connection is 85 feet. This distance is the adjacent side of the triangle, so we can write:
tan(17°) = opposite / 85
Solving for the opposite side, we get:
opposite = 85 tan(17°)
Substituting this into the formula for the hypotenuse, we get:
hypotenuse = (85 tan(17°)) / sin(17°)
hypotenuse ≈ 296.26 feet
Therefore, the electrician needs approximately 296.26 feet of wire.

If the temperature increases and the amount of water vapor in the air remains unchanged, how has the RH (relative humidity) changed?
When the temperature increases and the water vapor content in the air stays the same, the relative humidity decreases. This is because warmer air can hold more moisture than colder air, and therefore the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor that the air can hold decreases as the air temperature increases.
Relative humidity depends on two factors: the amount of water vapor present in the air and the maximum amount of water vapor that the air can hold at a given temperature. As the temperature rises, so does the amount of water vapor that the air can hold, since warm air has more energy to hold the water molecules in vapor form. This reduces the ratio of the actual amount of water vapor in the air to the maximum amount of water vapor the air can hold, resulting in lower relative humidity.

The Unit-Price for first-bag is $1.72/kg and for second-bag is $1.86/kg, then the first-bag is cheaper compared to the second-bag with a unit-price.
The "Unit-Price" refers to the cost of dog food per kilogram. It is calculated by dividing the "total-cost" of the bag of dog-food by its weight in kilograms.
⇒ For the first bag of dog food:
The Cost is = $10.47,
The Weight is = 6.08 kg,
So, the Unit-Price is = Cost/Weight = $10.47/6.08 kg ≈ $1.72/kg,
⇒ For the second bag of dog food:
The Cost is = $13.88,
The Weight is = 7.48 kg,
So, the Unit Price will be = Cost/Weight = $13.88/7.48 kg ≈ $1.86/kg,
Based on the "unit-prices" calculated, the first bag of dog food has a unit price of $1.72 per kilogram, and the second bag has a unit price of $1.86 per kilogram.

If the mogav train travels at a consistent speed of 480 km/h for one fourth of an hour how far does the train travel
The train travels a distance of 120 kilometers.
To calculate the distance traveled by the train, we can use the formula:
Distance = Speed × Time
Given that the train travels at a consistent speed of 480 km/h and the time is one-fourth of an hour, we can substitute these values into the formula:
Distance = 480 km/h × (1/4) hour
To simplify the calculation, we can convert one-fourth of an hour to minutes. Since there are 60 minutes in an hour, one-fourth of an hour is equal to (1/4) × 60 minutes = 15 minutes.
Now, we can calculate the distance:
Distance = 480 km/h × (1/4) hour
= 480 km/h × (1/4) × 60 minutes / 60 (converting hours to minutes)
= 480 km/h × 15 minutes / 60
= 480 km/h × 0.25

Specifically, a vertical translation of distance c is given by the function:
f(x) + c
where f(x) is the original function and c is a constant that determines the amount and direction of the translation. If c is positive, the graph of the function is shifted upwards; if c is negative, the graph is shifted downwards.
For example, the function f(x) = x^2 has a graph that is a parabola opening upwards. If we apply a vertical translation of 2 units, the resulting function is:
f(x) + 2 = x^2 + 2
The graph of this function is also a parabola, but it has been shifted vertically upwards by 2 units. Similarly, a vertical translation of -3 units would give us the function f(x) - 3 = x^2 - 3, which is the same parabola shifted downwards by 3 units.
