1) 10-2v = -5v-50 2) r+15=4r-6 write all !

1) 10-2v=-5v-50 (add 5v on both sides)
    10+3v=  -50 (subtract 10 on both sides)
     3v  = -60   (divide by 3)
      v= -20
2) r+15= 4r-6 (add 6 on both sides)
    r+ 21= 4r (subtract 1r on both sides)
    21= 3r (divide by 3)
    7= r

  C.  f^-1(x) = (x +4)^2; x  ≥ -4

Step-by-step explanation:

The range of the given function f(x) is -4 ≤ f(x). This will be the domain of the inverse function.

We find the inverse function by solving ...

  x = f(y)

  x = √y -4

  x +4 = √y

  (x +4)^2 = y

The inverse function is ...

  f^-1(x) = (x +4)^2 . . . for x ≥ -4
