Answer:

see explanation

Step-by-step explanation:

let y = f(x) then rearrange making x the subject

y = 2x - 10 ( add 10 to both sides )

y + 10 = 2x ( divide both sides by 2 )

\frac{y+10}{2} = x

Change y back into terms of x

f^{-1} (x) = \frac{x+10}{2}

Which equation can be used to find the unknown length, b, in this triangle?
Romashka-Z-Leto [24]

The equation for finding the hypotneus of a right triangle is
{a }^{2}  +  {b}^{2}  = c {}^{2}
so we know that 4²+b²=5²
so that would simplify as 16+b=25
so x=25-16
which is 9
so therefore we can conclude that
b = 9inches
