Expressed as a ratio, the board lengths are 1:3.

Then the sum of the "ratio units" is 1+3=4, so each "ratio unit" must represent (48 in)/4 = 12 in of board.

The piece that is 1 ratio unit long is 1*12 in = 12 in.
The piece that is 3 ratio units long is 3*12 in = 36 in.

The pieces are 12 in and 36 in long.

Find the inverse of the function f(x)=5x-6/x+2

Naily [24]

Answer:

$f^{-1}(x)=\dfrac{2x+6}{5-x}$

Step-by-step explanation:

Swap x and y, then solve for y.

$x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}$
