F^-1(x)= x/9 + 1/3
To find this, just interchange the variables and solve for y.
y=9x-3 
x=9y-3
x+3=9y
divide by nine
        
             
        
        
        
<span>323° in radians
= 323 x pi / 180
= 5.6
answer is 
</span><span>B. 5.6</span>
        
             
        
        
        
Divide 25 by 4 and you get 6 with a remainder of 1. That remainder of 1 can go over 4 to create the final answer of 6 and 1/4.
