Answer:
Since in your question you don't specify the coordinates of any of them, the best answer would be (-x, y) since that is the formula to find the reflection over the y-axis.
X= 20
Work:

7 times 2 is 14 so you will
muliltiply 10 by 2 which is 20.
Answer:
x = 22
Step-by-step explanation:
same- side exterior angles are supplementary, thus
4x + 15 + 3x + 11 = 180, that is
7x + 26 = 180 ( subtract 26 from both sides )
7x = 154 ( divide both sides by 7 )
x = 22
Your answer is gonna be a.) 12yd^2
Slope: -3/2
Y: 7/2
