Solution

Solution Steps

To evaluate the given algebraic expressions for the specified values, substitute the given values into each expression and perform the arithmetic operations. This will yield the numerical result for each expression.

Step 1: Evaluate $7x - 3$ for $x = -5$

To evaluate the expression $7x - 3$ for $x = -5$, substitute $-5$ for $x$ in the expression: \[ 7(-5) - 3 = -35 - 3 = -38 \]

Step 2: Evaluate $4 - 6x$ for $x = -9$

To evaluate the expression $4 - 6x$ for $x = -9$, substitute $-9$ for $x$ in the expression: \[ 4 - 6(-9) = 4 + 54 = 58 \]

Step 3: Evaluate $\frac{1}{2}bh$ for $b = 7$ and $h = 9.5$

To evaluate the expression $\frac{1}{2}bh$ for $b = 7$ and $h = 9.5$, substitute $7$ for $b$ and $9.5$ for $h$ in the expression: \[ \frac{1}{2} \times 7 \times 9.5 = \frac{1}{2} \times 66.5 = 33.25 \]
