When the equations 3x 5y 9 and 5x 3y 7 are solved then the value of x y 2?

The equation of line in slope intercept form is,

⇒ y = x - 2

When the graph is shift down 9 units.

Then, Equation of line become,

⇒ y = x - 11

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (2, 0) and (0, -2).

Now,

Since, The equation of line passes through the points (2, 0) and (0, -2).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 2 - 0) / (0 - 2)

m = - 2 / -2

m = 1

Thus, The equation of line with slope 1 is,

⇒ y - 0 = 1 (x - 2)

⇒ y = x - 2

And, When the graph is shift down 9 units.

Then, Equation of line become,

⇒ y = x - 2 - 9

⇒ y = x - 11

Therefore, The equation of line in slope intercept form is,

⇒ y = x - 2

Answer: x= 96 degrees

Step-by-step explanation:

It we figure out the rest of the angles they would be (the outside ans inside angles are straight angles):

The equation and the answer of this question is 1.20 + 3.25x = 40.20, x = 12

According to the information that has been provided to us, the cost that the taxi company charged was $1.20, in addition to $3.25 per mile, for a total fare of $40.20.

Therefore, the equation would be:

1.20 + 3.25X = 40.20

To find the distance from Zoey’s house to the airport we need to calculate the value of X

1.20 + 3.25X = 40.20

3.25X = 39

X = 39 : 3.25

Answer:

This equation can be used to determine how long the car was traveling at each speed. You can solve for one of the variables by using algebraic techniques. For example, you could subtract 35y from both sides to get:

55x = 200 - 35y

Then divide both sides by 55 to get:

x = (200 - 35y)/55

This equation shows that the value of x (the time spent traveling at 55 mph) is determined by the value of y (the time spent traveling at 35 mph). If you know the value of y, you can use this equation to calculate the value of x.

To find the values of x and y that satisfy the equation, you will need to use additional information. For example, you could set up a system of equations and solve for x and y using techniques such as substitution or elimination.

Step-by-step explanation:

The piecewise function represented by the graph is:

f(x) = 2x when -3 ≤ x < 0

f(x) = 3 When 1/2 < x < 3/2

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Let f(x) = y = mx + c

From the graph, when -3 ≤ x < 0.

(-3, -6) and (-1, -2)

m = (-2 + 6) / (-1 + 3) = 4 / 2 = 2

(-1, -2) = (x, y)

-2 = 2 x (-1) + c

-2 = -2 + c

c = 0

f(x) = 2x

From the graph, When 1/2 < x < 3/2.

It is a horizontal line of y = 3.

f(x) = 3

Therefore , the solution of standard deviation is  because the value of 1452.2 cm3 does not fall between the range of 917.4 cm3 and 1422.2 cm3.

Standard deviation, often known as variance in a set of data, is a statistical measure of variation. A low standard deviation indicates that the values are more likely to be near the mean of the collection, whereas a high standard deviation indicates that the values are widely distributed. How far the data depart from the mean is expressed by the standard deviation, abbreviated as.

Here,

Considering the details here,

The average brain volume is 1169.8 cm3, while the standard deviation is 126.2 cm3.

The much lower results are u-2 = 11169.8-2(126.2) => 917.4.

Reason: According to the range rule of thumb, the required incredibly low values are 91.7 cm3 or less.

Hint: Use the algorithm to identify values that are at least considerably high.

Step: 2

Considering the data supplied,

The average brain volume is 1169.8 cm3, while the standard deviation is 126.2 cm3.

Significantly higher values include,

u-2α = 11169.8+ 2(126.2)

=> 1422.2

Justification: According to the range rule of thumb, the necessary significantly high values must be 1422.2 cm3 or higher.

Hint: To determine whether the value 1452.2 cm3 is very high, use the findings of steps (1) and (2).

Step: 3

Using step 1 and step (4),

917.4 is among the significantly low numbers or less.

The significantly high values are 1422.2 or higher.

Yes, 1452.2 cm3 is a noticeably high value.

The apt response is choice (B).

Reason: The value is much higher than expected based on the range rule of thumb because the value of 1452.2 cm3 does not fall between the range of 917.4 cm3 and 1422.2 cm3.

The committee might consist of only 1 person or up to 23 people.

Let N represent the maximum possible number of such committees.

The total number of prime numbers that divide N must be determined.

The number of ladies chosen will be m.

The number of guys who were not chosen would thus be:

11 - (m - 1) = 12 - m

Each pairing of men who were not chosen and women who were chosen represents a committee choice.

Since selecting 12 people from a total of 23 would result in m women and 12 - m males, the committee chose:

The robot is moving in the direction indicated by the formula ((i)²¹*(-i)²²)d, or in the beginning direction.

What is complex plain?

When a line is rotated in the complex plane either clockwise or anticlockwise, it is multiplied by -i or I depending on which direction the line is rotated. The direction vector is rotated 90 degrees in the clockwise direction to make a right turn. It is the same as increasing the complex number by -i.

A left turn is represented as a 90° anticlockwise rotation of the direction vector. It is comparable to increasing the complex number by i.

There are 21 left turns of the robot. The direction vector will now be di21. Once it has been rotated 22 times to the right, the direction vector will now be  (di²¹)*(-i)²²=d((i)²¹*(-i)²²).

Consequently, the robot's current direction is:

d((i)²¹*(-i)²²)= di²¹⁺²²=di⁴³= d(-i)= -di

No matter what, the direction will always be the same, hence the sequence is irrelevant.

Hence, the equation that will indicate where the robot is moving is  ((i)²¹*(-i)²²)d, or in the starting direction. Furthermore, the final direction it faces does not depend on the order.

Since, We know that;

Parallel lines have same slopes and different y-intercepts

The formula of the slope of a line which passes through points (x₁ , y₁) and (x₂, y₂) is,

⇒  m = (y₂ - y₁) / (x₂ - x₁)

Since, The given line passes through points (-12 , -2) and (0 , -4)

Hence, Use the formula of the slope above to find the slope of the given line as;

⇒ m = (y₂ - y₁) / (x₂ - x₁)

⇒ m = (-4 - (-2)) / (0 - (-12))

⇒ m = (-2) / 12

⇒ m = - 1/6

Since, The two lines are parallel.

Hence, Their slopes are equal

So, The slope of the parallel line = - 1/6

Here, The parallel line passes through point (0 , 6)

Since, The form of the linear equation is y = mx + b, where m is the slope and b is the y-intercept.

⇒ m = -1/6 and b = 6
