What does y equal in this equation 5(y+2/5)=-13

Korolek [52]

Steps to solve:

5(y + 2/5) = -13

~Distributive Property

(5 * y) + (5 * 2/5) = -13

~Simplify

5y + 2 = -13

~Subtract 2 to both sides

5y + 2 - 2 = -13 - 2

~Simplify

5y = -15

~Divide 5 to both sides

5y/5 = -15/5

~Simplify

y = -3

Best of Luck!

Determine the image of the point (-5,-1) under a rotation of 90 about the origin

lukranit [14]

The rule for a 90 degree rotation is

(x,y)——>(-y,x)

So let’s take the coordinate (-5,-1) and let’s replace the x and y places together!!!

So that would give us -1•-1 which is just 1
Then -5•1 which is just -5

So the answer is

(1,-5)
