No, they forgot to switch variable labels after solving for the independent variable...
y=-8x+4
y-4=-8x
(y-4)/-8=x 
Now that you have solved for the independent variable x, you switch the variable labels...
y=(x-4)/-8 
f^-1(x)=(x-4)/-8     which should really be rewritten as:
f^-1(x)=(4-x)/8  :P
        
                    
             
        
        
        
A circle is a fixed distance from all other points on the circle
        
             
        
        
        
Answer:
Transitive Property 
Step-by-step explanation:
Since X is the midpoint, it bisects the points RS. If MX=XS, and RS is the same as XS, then they are the same. This also follows the Transitive propety  (if a=b and b=c, then a=c)
 
        
             
        
        
        
I don’t know the answer but I can tell you how to do it subtract starting value minus final value divide that amount by the absolute value of the starting value multiply by 100 to get percent decrease if the percentage is negative it means there was an increase not a decrease
