Question

solve for x and graph the solution on the number line below. -72 > -9x answer attempt 2 out of 3 < > ≤ ≥ or inequality notation: x > 8 number line: click line to delete. click closed circle to change to open circle. submit answer

Explanation:

Step1: Divide both sides by -9

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

Step2: Simplify

Simplifying gives $8 < x$, which is equivalent to $x>8$.

Answer:

Inequality Notation: $x > 8$. On the number - line, there is an open circle at $8$ (since $x$ is not equal to $8$) and the line extends to the right (towards larger numbers) from $8$.
