Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2

Answer:
1 hour and 45 mins
Step-by-step explanation:
As mentioned,
Starting time = 2:30 PM
Ending time = 4:15 PM
The given time is in hours and minutes, to calculate the duration of movie, time should be converted into a same unite minutes.
1 hour = 60 minutes
Therefore,
2:30 = 2 hours and 30 mins = 2*60 + 30 mins = 150 mins
4:15 = 4 hours and 15 mins = 4*60 + 15 mins = 255 mins
The duration = Ending time - Starting time
=> 255 - 150
=> 105 mins
or
60 + 45
1 hour and 45 mins
