Need help with these two problems! 1. use the associative, commutative, and distribute properties to prove the expression 7(3y-5) -2(10+4y) is equivalent to the expression 13y-55.
2. prove algebraically that each expression has the same value by evaluating each expression for y=5, 7(3y-5) -2(10+4y), 13y-55.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
