Answer:
The inverse is x-8 
Step-by-step explanation:
g(x) = x+8
y = x+8
To find the inverse, exchange x and y
x = y+8
Solve for y
Subtract 8 from each side
x-8 = y+8-8
x-8 = y
The inverse is x-8 
 
        
             
        
        
        
To get the answer, all you have to do is 715 ÷ 55 which equals 13 (hours)
        
                    
             
        
        
        
Here are some simple equations that can be a life saver with this stuff :
vol of a sphere =

Circumference = 

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.
then take the answer u got for ^^ and divide it by 2? not sure.
 
        
             
        
        
        
4 : 28 is the same as 4/28 
4/28 = 1/7 
The answer is C
