Question

use the drawing tools to form the correct answer on the number line. graph the solution to this inequality on the number line. -2 < 2x + 6 < 20

Explanation:

Step1: Subtract 6 from all parts

$-2 - 6<2x + 6-6<20 - 6$
$-8<2x<14$

Step2: Divide all parts by 2

$\frac{-8}{2}<\frac{2x}{2}<\frac{14}{2}$
$-4 < x<7$

Answer:

On the number - line, there should be an open circle at - 4, an open circle at 7, and the line segment between them should be shaded.
