Convert to a mixed number:
239/42

Divide 239 by 42:
4 | 2 | 2 | 3 | 9

42 goes into 239 at most 5 times:
 | | | | 5
4 | 2 | 2 | 3 | 9
 | - | 2 | 1 | 0
 | | | 2 | 9

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
 | | | | 5 | (quotient)
4 | 2 | 2 | 3 | 9 | 
 | - | 2 | 1 | 0 | 
 | | | 2 | 9 | (remainder)


The quotient of 239/42 is 5 with remainder 29, so:

What is the inverse of f(x)= 3x-9
JulsSmile [24]

If f^{-1}(x) is the inverse of f(x), then

f\left(f^{-1}(x)\right) = x

Given

f(x) = 3x-9

composing with the inverse function gives

f\left(f^{-1}(x)\right) = 3f^{-1}(x) - 9 = x

Solve for the inverse:

3f^{-1}(x)-9 = x \\\\ 3f^{-1}(x) = x+9 \\\\ \boxed{f^{-1}(x) = \dfrac x3 + 3}
