Answer:
x = 8.75, y = 8.125
Step-by-step explanation:
The triangles are similar thus the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
8x = 70 ( divide both sides by 8 )
x = 8.75
And
= 
( cross- multiply )
8y = 65 ( divide both sides by 8 )
y = 8.125
Answer:
<h3>
R(-1, -9)</h3>
Step-by-step explanation:
When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign
in means if R = (x, y) then R' = (x, -y)
so we have:
x = -1 and -y = 9
y = -9
which gives R = (-1, -9)
Answer:
3 1/2 
21/4
Step-by-step explanation:
3 1/2= 7/2= 7 divided by 2=
21/4=21 divided by 4=
![\sqrt[4]{21}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B21%7D)
4 goes into 21, five times which is 5 1/4
![\sqrt[2]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B7%7D)
2 goes into 7, six times which is 6 1/2

<h3>
Answer: Choice C</h3>
=============================================
Explanation:
Choices A, B and D are not true because of the negative y values. The result of an absolute value is never negative. So we can rule out choices A, B, and D. We have choice C as the only thing left, so this must be the answer.
-------------
Another way to see this is by plugging in each x value to see what y value comes out.
- If x = -2, then y = |5*x| = |5*(-2)| = |-10| = 10
- If x = -1, then y = |5*x| = |5*(-1)| = |-5| = 5
- If x = 0, then y = |5*x| = |5*0| = |0| = 0
- If x = 1, then y = |5*x| = |5*1| = |5| = 5
- If x = 2, then y = |5*x| = |5*2| = |10| = 10
The y outputs from top to bottom are: 10, 5, 0, 5, 10
This matches with what choice C shows.
