Answer:
Let X be the number of weeks.
2x - 16 = 14
we add 16 on both sides.
2x = 30
now we divide 2 on both sides to get rid of the 2 to the x, we want to get x on its own.
X = 15
6x = 3x + 12 so 3x = 12 then x = 4

If the units in the equation are in feet, it lef5t at a height of 7.4 feet (or meters, etc.).
Step-by-step explanation:
p(x) = - 0.013x2 + 0.02x + 7.4
When x, the time, = 0 [just before it leaves the pitcher's hand]
p(0) = 7.4
