$y= \dfrac{2}{x+4} \\ \\ 
y(x+4)=2 \\ 
x+4= \frac{2}{y} \\ 
x= \dfrac{2}{y} -4\;\;\;\;\Rightarrow f^{-1}(x)= \dfrac{2}{x} -4$

Answer:

x = 6

Step-by-step explanation:

The angle bisector divides the sides proportionally.

(6x -1)/42 = (10x +5)/78

13(6x -1) = 7(10x +5) . . . . . . . multiply by 546 = LCM(42, 78)

78x -13 = 70x +35 . . . . . . . . eliminate parentheses

8x = 48 . . . . . . . . . . . . . . . . add 13-70x

x = 6 . . . . . . . . . . . . . . . . . divide by 8
