Answer:
Step-by-step explanation:
Add the 2 equations
-7x+8x = 13-14
x=-1
7-y=13
-y = 6
y=-6
for the ball to get to the ground the h=0 no hight it is now in the base point.
substitute the value t=0 into the equation we get 64.
since we want to know the time in seconds then we should subtract 60 from 64 (64-60=4)
then my answer is 0-4.
I'm not sure it's correct just wait for others to respond
I THINK its -5x-2+3x^2 but someone please check me on that
