Question

solve and graph the following inequality: 4 ≤ 8x

Explanation:

Step1: Isolate x

Divide both sides by 8: $\frac{4}{8}\leq\frac{8x}{8}$

Step2: Simplify

$\frac{1}{2}\leq x$ or $x\geq\frac{1}{2}$

Answer:

Inequality: $x\geq\frac{1}{2}$
Graph: On a number - line, put a closed circle at $\frac{1}{2}$ (because the inequality is $\geq$) and shade to the right.
