Y - 5 = 3 - 9(y + 2)
Expand the brackets
y - 5 = 3 - 9y + 18
Move y to one side, and constants to the other
10y = 26
Solve for y
y = (26 / 10) = 2.6

Answer: 4 seconds
Step-by-step explanation:
Given: The function
can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get

Put h'(t)=0

Also, 
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
