Question

solve the inequality and graph the solution on the line provided. -10 + 2x ≤ -18 answer < > ≤ ≥ or inequality notation: number line: -12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12

Explanation:

Step1: Add 10 to both sides

$-10 + 2x+10\leq - 18+10$
$2x\leq - 8$

Step2: Divide both sides by 2

$\frac{2x}{2}\leq\frac{-8}{2}$
$x\leq - 4$

Answer:

$\leq$; $x\leq - 4$
To graph on the number - line: Draw a closed circle at - 4 (because the inequality is $\leq$) and shade to the left of - 4.
