Answer:
a. y = -x
b. Area = xy
c. x = -y
Explanation:
a. The perimeter of the garden is the distance all the way around, in this would be x+y+x+y, or 2x + 2y. To solve for y, we’re trying to isolate it on one side. We need to subtract 2x to get 2y = -2x. Divide by 2 to get y = -x.
b. Area is length times width, so x • y, or xy.
c. To express in terms of x, we can take the equation y = -x and multiply it by -1 to get x = -y
