Answer:
y = - 13, y = 13
Step-by-step explanation:
Given
y² = 169 ( take the square root of both sides )
y = ±  = ± 13
 = ± 13
Since 13 × 13 = 169 and - 13 × - 13 = 169
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
If we have y=7x-1/2, the inverse is where we solve for x instead of y.
We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.
Therefore,  .

$520.
y=10x+20 
Where x is the amount of cars.
y=10(50)+20
y=500+20
y=$520
