Question

solve for x and graph the solution on the number line below.
-21 ≥ -7x
answer attempt 1 out of 2
< > ≤ ≥ or
inequality notation:
number line:

Explanation:

Step1: Divide both sides by -7

$$\frac{-21}{-7}\leq\frac{-7x}{-7}$$

Step2: Simplify

$$3\leq x$$

Answer:

Inequality Notation: $x\geq3$

To graph on the number line: place a closed circle at $3$ (because the inequality is $\geq$) and shade to the right.
