Answer:

$f^{-1}$ (x) = $\frac{x-3}{5}$

Step-by-step explanation:

Rearrange the equation making x the subject

y = 5x + 3 ( subtract 3 from both sides )

y - 3 = 5x ( divide both sides by 5 )

$\frac{y-3}{5}$ = x

Change y to x then

$f^{-1}$ (x) = $\frac{x-3}{5}$

Solve each equation for y:

sammy [17]

Step-by-step explanation:

${y}^{2} - 1 = 80$

${y}^{2} = 81$

$y = ±9$

$\frac{y - 4}{4} = 1$

$y - 4 = 4$

$y = 8$

$\frac{10 - 63}{y} = 1$

$10 - 63 = y$

$- 53 = y$
