Step-by-step explanation:
Given : 
To Find: How many seconds does it take for the golf ball to hit the ground?
Solution :
Since we are given an equation : 
Where H denotes height
t denotes the number of seconds elapsed since the ball was hit.
When he golf ball to hit the ground at that time the height becomes 0
So, put H = 0 in the equation






Thus it take 4 seconds for the golf ball to hit the ground
This fraction cannot be turned into a mixed number but it can be reduced to

or 0.75
hope this helps
the x s are the independent variable so any direct change to them is changing the independent. like the second one has -5 on the x
