Aball is rolling down a hill. at one point near the top of the hill, its velocity is 2 m/s. further down the hill, its velocity is 9 m/s. what is ? v? 9 m/s 7 m/s -7m/s -7m/s2

The answer is 7 m/s!

I hope this helped!

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
