2y-8x=6 which of the following pairs satisfies the equations (1,8) (6,27) (-2,8) (-8,-27) (-1,-1)
Answer:
Step-by-step explanation:
To determine which pairs satisfy the equation 2y - 8x = 6, we need to find values of x and y that make the equation true. One way to do this is to solve for y in terms of x:
2y - 8x = 6
2y = 8x + 6
y = 4x + 3
Now we can substitute different values of x into this equation and see what values of y we get. For example:
When x = 0, y = 3
When x = 1, y = 7
When x = -1, y = -1
When x = 2, y = 11/2
When x = -2, y = -5
So the pairs that satisfy the equation 2y - 8x = 6 are:
(0, 3), (1, 7), (-1, -1), (2, 11/2), (-2, -5)
In each of these pairs, when we substitute the values of x and y into the equation, we get a true statement
The triangles have the measures shown in the figure. What are the values of b and c ?
Reflection across x=3 is a transformation that involves reflecting a figure across a vertical line of symmetry at x=3.
What is triangle?Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.
This transformation produces a mirror image of the original figure. Reflection across x=3 can be represented in the form of a matrix equation,
A= [[-1, 0],
[ 0, 1]]
This matrix equation demonstrates that the x coordinates of a point will be multiplied by -1, while the y coordinates will remain unchanged. This transformation is also known as a reflection over the y-axis.
Reflection across x=3 can be used to change the orientation of a figure in a 2-dimensional coordinate plane. For example, if a triangle is located at the position (2,4) and the coordinates need to be changed so the triangle is reflected across x=3, the coordinates would be transformed to (-2,4).
Reflection across x=3 can also be used to solve various types of mathematical problems. For example, if a problem asks for the coordinates of a point that is the reflection of a point across x=3, the coordinates of the reflected point can be calculated by multiplying the original x coordinate by -1 and leaving the y coordinate unchanged.

Evaluate the integral by changing the order of integration in an appropriate way. ∫[infinity]0∫540∫9y6e−x2+zdxdydz
The value of the integral is π(540)^2.
What is the value of the integrationWe can change the order of integration as follows:
∫^(∞)(0)∫540∫9y6e−x2+zdxdydz = ∫^(540)(0)∫^∞_0∫^√(9y^6)_(−∞)e−x^2dzdxdy
The limits of z are from −∞ to ∞, but the integrand is an even function of z, so we can simplify the integral by taking the absolute value of the integrand and multiplying it by 2:
∫^(540)(0)∫^∞_0∫^√(9y^6)(−∞)e−x^2dzdxdy = 2∫^(540)_(0)∫^∞_0∫^√(9y^6)_0 e−x^2dzdxdy
We can now evaluate the integral with respect to z:
2∫^(540)_(0)∫^∞_0[√π/2 - √π/2erf(−√x^2+z)/2]|^√(9y^6)_0 dxdy
where erf is the error function.
Substituting the limits of integration and simplifying, we get:
2∫^(540)_(0)∫^∞_0[√π/2 - √π/2erf(−3y^3/√2x)/2]dxdy
Next, we can evaluate the integral with respect to x:
2∫^(540)_(0)[√π/2(x - √2/3y^3erf(−3y^3/√2x))]|^∞_0 dy
Since the limits of integration with respect to x are from 0 to ∞, the first term in the square brackets evaluates to ∞, and the second term evaluates to √π/2. Therefore, the integral reduces to:

Hello! I'd like some assistance with this question. For 'd', why can we only estimate the distances? Could anyone please elaborate on the whole question?
Answer:
Please Mark As Brainliest Answer
Step-by-step explanation:
In many contexts, we can estimate distances between objects or locations, but we may not always be able to measure them precisely. There are several reasons why we might only be able to estimate distances rather than measure them exactly:
Limitations of measuring instruments: The precision of a measuring instrument can limit our ability to measure distances accurately. For example, a ruler may only have markings up to a certain level of precision, so we may need to estimate distances between the markings.
The variability of the distance: In some cases, the distance we are measuring may be constantly changing, making it difficult to measure with precision. For example, if we are trying to measure the distance between two moving objects, the distance between them will constantly change, and we may need to estimate the distance at a particular moment in time.
Environmental factors: The environment can also make it difficult to measure distances precisely. For example, atmospheric conditions such as haze or fog can obscure objects and make it difficult to judge their distance accurately.
Human perception and judgment: Finally, our own perception and judgment can also limit our ability to measure distances accurately. For example, when estimating the distance to an object, our perception of the size of the object can affect our judgment of its distance.
In many cases, despite these limitations, estimates of distances can still be useful and informative. For example, in navigation, we may not need to know the exact distance between two points, but only an estimate that is accurate enough to help us navigate from one point to the other

Andrea works at two different jobs. She works no more
than 40 hours per week combined between the two jobs.
At one job, she makes $12 per hour. At her other job, she
makes $16 per hour. Each week she earns at least $460.
Andrea writes a system of inequalities to represent this
situation. One of her inequalities is shown below.
x+y≤40
What should be the other inequality in Andrea's system
of inequalities?
Answer:
Second inequality is
12x + 16y ≥ 460
We also have implied inequalities x ≥ 0, y ≥ 0 meaning hours cannot be negative
Step-by-step explanation:
The other equality refers to the earnings
Let x be the hours worked in the first job
Earnings at $12 per hour = 12x
Let y be the hours worked in the second job
Earnings at $16 per hour = 16y
Total earnings = 12x + 16y
This must be at least $460
"at least" means ≥
So second inequality is
12x + 16y ≥ 460
The drama club is selling tickets to their play to raise money for the show's expenses.
Each student ticket sells for $7 and each adult ticket sells for $10. The auditorium can
hold no more than 85 people. The drama club must make no less than $690 from
ticket sales to cover the show's costs. Also, they must sell a minimum of 10 student
tickets and at least 55 adult tickets. If a represents the number of student tickets sold
and y represents the number of adult tickets sold, write and solve a system of
inequalities graphically and determine one possible solution.
On solving the inequalities a ≥ 10, y ≥ 55, 7a + 10y ≥ 690, the solution is obtained as (20,55).
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
Use the variables a and y to represent the number of student and adult tickets sold, respectively.
Then write the following system of inequalities -
a ≥ 10 (they must sell a minimum of 10 student tickets)
y ≥ 55 (they must sell at least 55 adult tickets)
7a + 10y ≥ 690 (they must make no less than $690 from ticket sales)
The first two inequalities are constraints on the number of tickets sold, and the third inequality represents the revenue constraint.
To find a possible solution, graph these inequalities on a coordinate plane and look for the feasible region that satisfies all three inequalities.
Alternatively, solve the system of inequalities using algebra.
First, simplify the third inequality by subtracting 7a from both sides -
10y ≥ 690 - 7a
Then, divide both sides by 10 -
y ≥ (690 - 7a)/10
This inequality represents the revenue constraint in terms of the number of student tickets sold.
Now combine the revenue constraint with the other two constraints -
a ≥ 10
y ≥ 55
y ≥ (690 - 7a)/10
Use substitution to solve for a in terms of y -
y ≥ (690 - 7a)/10
10y ≥ 690 - 7a
7a ≥ 690 - 10y
a ≥ (690 - 10y)/7
To find a possible solution, substitute a = (690 - 10y)/7 into the other two constraints -
(690 - 10y)/7 ≥ 10
y ≥ 55
These inequalities can be simplified -
690 - 10y ≥ 70
y ≥ 55
The first inequality can be solved for y -
-10y ≥ -620
y ≤ 62
Since it is known y ≥ 55, the feasible values for y are between 55 and 62, inclusive -
55 ≤ y ≤ 62
Now use the expression for a in terms of y to find the corresponding values of a -
a = (690 - 10y)/7
For each value of y between 55 and 62, inclusive, we can calculate a and check whether it satisfies the constraints -
a ≥ 10
y ≥ 55
7a + 10y ≥ 690
For example, when y = 55 -
a = (690 - 10(55))/7 = 20
7a + 10y = 7(20) + 10(55) = 690
Therefore, these values satisfy all three constraints, so one possible solution is a = 20 and y = 55.

Compare the investment below to an investment of the same principal at the same rate compounded annually. principal: $1,000, annual interest: 3%, interest periods: 4 , number of years: 15
The investment with annual compounding yields a higher future value of $1,520.10 compared to $1,489.36 for the given investment method.
What is compounding?The process through which an investment earns returns on both the principal and the accrued interest over time is known as compounding. To put it another way, it is the reinvestment of interest income into an investment that enables the investment to increase exponentially over time.
Compounding works on the basic premise that interest earned on an investment is added to the principal amount. The interest is then calculated using the new, higher principal amount during the subsequent interest period, yielding even more interest. When the money generated is reinvested and grows over time, this cycle keeps repeating, increasing the investment's value more swiftly.
The investment given has a principal of $1,000, an annual interest rate of 3%, and interest periods of 4 per year. The investment is held for 15 years. To compare this investment to one with the same principal and annual interest rate compounded annually, we need to calculate the future value of the investment using both methods and compare the results.
Using the given investment method, we can calculate the future value as follows:
FV = P(1 + r/n)^(nt)
FV = 1000(1 + 0.03/4)^(4*15)
FV = $1,489.36
Using annual compounding, we can calculate the future value as:
FV = P(1 + r)^t
FV = 1000(1 + 0.03)^15
FV = $1,520.10
So, the investment with annual compounding yields a higher future value of $1,520.10 compared to $1,489.36 for the given investment method. This difference occurs because compounding more frequently leads to more frequent accumulation of interest, resulting in a higher final amount.

The quadratic equation y = 4 · x² + 28 · x + 49 is a perfect square trinomial.
Finally, we determine the dimensions of a rectangle whose area is the quadratic equation A = 6 · x² + 5 · x - 4. The area formula for a rectangle is described by the following formula:
A = b · h
Where:
b - Baseh - HeightThen, the factored form of the quadratic equation is:
A = 6 · x² + 5 · x - 4
A = 6 · [x² + (5 / 6) · x - 2 / 3]
A = 6 · (x - 1 / 2) · (x + 4 / 3)
There are two possible configurations for the rectangle:
Configuration 1: b = 6 · (x - 1 / 2), h = x + 4 / 3
Configuration 2: b = 6 · (x + 4 / 3), h = x - 1 / 2

Find the measure of angle 1
Find the measure of angle 2
Answer:
Angle 1= 45°
Angle 2= 90°
Step-by-step explanation:
Angle is found when you divide 90 by 2
We do this because all edges of a square add up to 90 and this angle is split in half, which is why we divided by 2
The to find angle 2 you get 45 for the left side of the triangle, 45 on the right side add them, which will give you 90, then subtract from 180 because angles in triangle equals 180 when you do this you get 90.
