Answer:
Step-by-step explanation:
Here's the answers I got. Sorry super busy at school ahh
Subsitute 9 for y
9=y=9x-9
add 9 to both sides
9+9=9x+9-9
18=9x+0
18=9x
divide by 9
2=x
y=9
x=2
Its a square, so all the sides are equal. Also, since the area of a square (rectangles) is equal to the height times the length, which are both the same, the area of the square is equal to x², where x is the length of any one side of the square, x²=256. now you square root both sides of that equation, x=√256, and the square root of 256 is 16.
Tl;Dr: each side is 16 feet long.
(-5, 15)
This is because y = 11 is a flat line that is 4 away from the point. Thus, the new point must also be 4 away from the line.
