A-32.

Read the Math Notes box in this lesson. Evaluate the expressions below for the given values of $x$ and $y$.

Rewrite the expression with the number in place of the variable and simplify if possible.

1. $\frac{6}{x}+9\text{ if }x=3$

$11$

1. $−x^{2} + y \text{ if } x = 2 \text{ and } y = 1$

$−(2)² + 1$

1. $−2xy \text{ if }x = 5 \text{ and } y = −3$

$−2\left(5\right)\left(−3\right) = −10\left(−3\right)$

$30$

1. $2x^{2} − y \text{ if }x = −3 \text{ and } y = 8$

$2\left(−3\right)² − \left(8\right)$
