Lydia and her children went into a grocery store where they sell apples for $0.75 each and peaches for $0.50 each. Lydia has $6 to spend and must buy a minimum of 9 apples and peaches altogether. If x represents the number of apples purchased and y represents the number of peaches purchased, write and solve a system of inequalities graphically and determine one possible solution

When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0 = -(x-2)^2 + 16

(x-2)^2 = 16

x-2 = 16

x-2 = 4

x = 6

This means the ball will hit the ground 6 seconds after Amir threw it.
