2(3x - 4) = 2x + 12
6x - 8 = 2x + 12
4x = 20
x = 5
AB = 3(5) - 4 = 11
AC = 2(5) + 12 = 22
BC = 7(5) - 2 = 35 - 2 = 33
AC:BC = 22:33 = 2:3

Answer: The initial height of the ball is 12 feet.
Step-by-step explanation:
We have the function
, which models the height (in feet) of the ball after
seconds.
Then, as the height is in function of the time, we know that the ball is in the initial height when:

So, to find the initial height, you need to substitute
into the function:

Therefore, the initial height of the ball is 12 feet.
