Question

solve for $x$ and graph the solution on the number line below.

$-10x > 80$

answer attempt 1 out of 2

< > ≤ ≥ or

inequality notation:

number line:

-12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12

click and drag to plot line.

Explanation:

Step1: Divide both sides by -10

When dividing an inequality by a negative number, the direction of the inequality sign changes. So, $\frac{- 10x}{-10}<\frac{80}{-10}$.

Step2: Simplify the expressions

$x < - 8$.

Answer:

Inequality Notation: $x < - 8$
Number Line: Plot an open - circle at - 8 and draw an arrow to the left.
