Question

solve the inequality.
c + 15 ≤ -7
the solution is:
graph the solution.

Explanation:

Step1: Subtract 15 from both sides

$$\begin{align*} c + 15-15&\leq-7 - 15\\ c&\leq-22 \end{align*}$$

Answer:

$c\leq-22$

To graph the solution:

• Place a closed circle at $-22$ (because the inequality is $\leq$, so $-22$ is included in the solution set).
• Shade to the left of $-22$ (since $c$ is less than or equal to $-22$).
