Answer:

The height is 0 when it "drops".

3/2x + 9 = 0

3/2x = -9

3 = -9(2x)

3 = -18x

3/-18x

Change signs, time cant be negative.

x= 6

Another interpretation; Slope is negative it is falling. This interpretation is more accurate.

-3/2x + 9 = 0

-3/2x = -9

-3 = -9(2x)

-3 = -18x

6 = x

AFTER 6 SECONDS
