Height in feet is represented by
The height of the ball is 0 feet when it hits the ground.
So we replace height f(x) by 0 and solve for x to find the time taken to reach the ground
( divide by -16 on both sides)
Now factor it
(x-6)(x+1) =0
x-6 =0 and x+1=0
x=6 and x=-1
Time cannot be negative so we ignore -1
x = 6 seconds
It will take 6 seconds for the ball to reach the ground.
3x+3y=27
x-3y= -11
-x-y=-9
x-3y=-11
-4y= -20
y= 5
x-3•5= -11
x=4
(x,y)= (4,5)
