Question

solve the inequality and graph the solution.

$\frac{d}{8}-7leq -8$

to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it.

Explanation:

Step1: Add 7 to both sides

$\frac{d}{8}-7 + 7\leq - 8+7$
$\frac{d}{8}\leq - 1$

Step2: Multiply both sides by 8

$\frac{d}{8}\times8\leq - 1\times8$
$d\leq - 8$

Answer:

The solution of the inequality is $d\leq - 8$. On the number - line, plot a closed circle at $-8$ (since the inequality is $\leq$) and draw an arrow to the left.
