Answer:
B
Step-by-step explanation:
So we have the function: 

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus: 

Subtract 32 from both sides: 

Multiply both sides by 5/9. The right side will cancel. Thus: 

Our answer is B. 
And we're done!
 
        
                    
             
        
        
        
Answer:
X= 1/2 Y= 5
Step-by-step explanation:
8x+7y=39-------------(1)--------×2
4x-14y= -68-----------(2)-------×1
16X + 14Y = 78--------(3)
4X- 14Y = -68----------(4)
Addy equation (4) and (3)
20X = 10
dividing bothsides by 20
20X/20= 10/20
 X = 1/2
substitute the value of X into equation (1)
8X+7Y = 39
8(1/2)+7Y= 39
4+7Y = 39
7Y = 39-4
7Y = 35
dividing bothsides 7
7Y= 35/7
Y = 5
 
        
             
        
        
        
32/3.2 = 3.2c/3.2
c = 32/3.2
c = 10
