Question

solve for x and graph the solution on the number line below. -72 > -9x answer < > ≤ ≥ or inequality notation: number line: -12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12

Explanation:

Step1: Divide both sides by -9

When dividing an inequality by a negative number, the direction of the inequality sign changes. So, $\frac{-72}{-9}<\frac{-9x}{-9}$.
$8 < x$

Answer:

$x>8$
On the number - line, you would place an open circle at 8 (since 8 is not included in the solution) and shade to the right of 8.
