Find y in each equation if $x = 16$. Homework Help ✎

1. $y=3+\sqrt[3]{x-8}$

Substitute $16$ into the equation for $x$.

$\small y=3+\sqrt[3]{16-8}$

Do the subtraction inside the root.

$\small y=3+\sqrt[3]{8}$

Find the cube root.
$y=3+2$
$y=5$
1. $y=\sqrt{x}-7$
1. $y=4+|9-x|$
Substitute $16$ into the equation for $x$, then do the subtraction inside the absolute value symbols before adding
