I do 10 - 8 for this, right...?

natima [27]

No, you would do 100 - 64 because 10^2 is 100 and 8^2 is 64.
100-64= 36
The square root of 36 is 6. The length of the other leg is 6.

Find the inverse of f(x)=-3x+3

kolezko [41]

To get the inverse, first off do a quick switch on the variables, and then solve for "y".

$\bf f(x)=y=-3x+3\qquad \qquad inverse\implies \boxed{x}=-3\boxed{y}+3
\\\\\\
x-3=-3y\implies \cfrac{x-3}{-3}=y\implies \cfrac{3-x}{3}=y\impliedby f^{-1}(x)$
