Step-by-step explanation:
3(a + b) = a + 2 expand
3a + 3b = a + 2
3a - a = 2 - 3b
2a = 2 - 3b
a = 2 - 3b

Find the length of the diagonal of a square with perimeter 56
Answers
Answer:
About 19.8
Step-by-step explanation:
First find the side lengths. In this example, 56/4=14
Next use the Pythagorean theorem, to us it, here's the formula a squared plus b squared equals c squared. For this example use 14 squared plus 14 squared which equals 392.
Finally take the square root of 392 because we still need to take the squared out in c. The square root of 392 rounded to the nearest tenth is 19.8.

PLEASE HELP ME!!! Point Q is located at (-4, 6) Point R is located at (8, 6)
what is the distance from point Q to point R?
Answers
R = (8, 6)
You can work out the distance between the points by doing the following formula:
√(x₂ - x₁)² + (y₂ - y₁)²
Factor in our points:
√(8 - -4)² + (6 - 6)²
Solve the brackets (remember a negative and a negative make a positive):
√(12)² + (0)²
= √144 + 0
= √144
Solve this expression to get your final answer of the distance between two points:
√144 = 12

The league raised $1,560 through fundraisers. Trenton estimates the cost of buying jackets for each player in the league. He concludes that the league has raised enough money. Do you agree with Trenton? Explain.
Answers
Answer:
Step-by-step explanation:
Estimates are rough guesses based on current or previous prices. Therefore, it is impossible to conclude whether or not Trenton has actually raised enough money, especially if no actual price for the jackets has been provided. That being said an estimation is usually a close enough representation of the actual value, which would mean that the chances of having raised enough money (if that is what the estimates say) are pretty high.

Find the slope of the line. (-3/2, -3/2) (3/2, 3/2)
Answers
Answer:
1
Step-by-step explanation:
1st way: We can find the slope of the line by plugging the two points into the slope formula. If you do, slope would be (-3/2-3/2)/(-3/2-3/2) which simplifies to -3/-3 which is 1. The slope is 1.
2nd way: You can just use logic to figure it out because since the x and y in both of the points are equal to each other, we know that the slope has to be 1.
Answer:
It is 1. You would put one in the positive section of the line graph, and put 1 in the negative section of the line graph. ≥ × ≤`

Answer:
x = 90 degrees and y = 43 degrees
Step-by-step explanation:
We have an isosceles triangle here, since the length of AB equals the length of AC.
That also means that angle ABC equals angle ACD = 47 degrees.
The sum of the interior angles of a triangle equals 180.
47 + 47 + 2y = 180
94 + 2y = 180
2y = 86
y = 43 degrees
x + 43 + 47 = 180
x + 90 = 180
x = 90

Answers
The range of this relation is [-2,4].
This relation is NOT a function. In order for a relation to be a function, each x-value needs to result in a singular y-value and pass the vertical line test. Since this is not true, the relation is not a function.
