Evaluate the expression for c = 1. Write your answer in simplest form. c - 3/-c - 6 = ____

Identify Expression: Identify the expression after substituting c = 1 Substitute 1 for c in c - 3/-c - 6. (1 - 3)/(-1 - 6)Substitute c=1: Evaluate 1 - 3 1 - 3 = -2 Numerator: -2Evaluate 1-3: Evaluate -1 - 6 -1 - 6 = -7 Denominator: -7Evaluate -1-6: -2/(-7) Rewrite the fraction in simplest form. Since both the numerator and the denominator are negative, the negatives cancel each other out. -2/(-7) = 2/7

Q. Evaluate the expression for

c = 1

\newline

Write your answer in simplest form.

\newline

\frac{c - 3}{-c - 6} =

Identify Expression: Identify the expression after substituting $c = 1$ $\newline$ Substitute $1$ for $c$ in $\frac{c - 3}{-c - 6}$ . $\newline$ $\frac{1 - 3}{-1 - 6}$
Substitute $c=1$ : Evaluate $1 - 3$ $1 - 3 = -2$ Numerator: $-2$
Evaluate $1-3$ : Evaluate $-1 - 6$ $-1 - 6 = -7$ Denominator: $-7$
Evaluate $-1-6$ : $-\frac{2}{(-7)}$ $\newline$ Rewrite the fraction in simplest form. $\newline$ Since both the numerator and the denominator are negative, the negatives cancel each other out. $\newline$ $-\frac{2}{(-7)} = \frac{2}{7}$
