420.69
Step-by-step explanation:
Answer:
f^-1(x) = x +6
Step-by-step explanation:
To find the inverse of the function
y = f(x)
solve the equation
x = f(y)
for y.
Here, you want ...
x = f(y)
x = (y -6)
x +6 = y . . . . . . add 6 to both sides

16 + 2x = 20
2x = 20 - 16 = 4
x = 4/2 = 2 inches
X + 12 + X - 6 = X + 50
2X + 6 = X + 50
X = 44
44 + 50 = 94
To check you can substitute X into the problem.
44 + 12 = 56
44 - 6 = 38
44 + 50 = 94
56 + 38 = 94
94 = 94
