Evaluate the expression for z = -2. Write your answer in simplest form. z - 2/-z + 7 = ____

Identify Expression: Identify the expression after substituting z = -2 Substitute -2 for z in z - 2/(-z + 7). ((-2) - 2)/(-(-2) + 7)Substitute and Simplify: Evaluate (-2) - 2 (-2) - 2 = -4 Numerator: -4Evaluate Numerator: Evaluate -(-2) + 7 -(-2) + 7 = 2 + 7 = 9 Denominator: 9Evaluate Denominator: -4/9 The fraction is already in its simplest form. Final expression: -4/9

Q. Evaluate the expression for

z = -2

\newline

Write your answer in simplest form.

\newline

\frac{z - 2}{-z + 7} =

Identify Expression: Identify the expression after substituting $z = -2$ $\newline$ Substitute $-2$ for $z$ in $\frac{z - 2}{-z + 7}$ . $\newline$ $\frac{(-2) - 2}{-(-2) + 7}$
Substitute and Simplify: Evaluate $(-2) - 2$ $(-2) - 2 = -4$ Numerator: $-4$
Evaluate Numerator: Evaluate $-(-2) + 7$ $-(-2) + 7 = 2 + 7 = 9$ Denominator: $9$
Evaluate Denominator: $-\frac{4}{9}$ $\newline$ The fraction is already in its simplest form. $\newline$ Final expression: $-\frac{4}{9}$
