Answer

$[2\frac{2}{3},\infty)$

Work Step by Step

$\frac{3x}{4}\geq2$ Solve for x. Multiply both sides by 4. $\frac{3x}{4}\times4\geq2\times4$ $3x\geq8$ Divide both sides by 3. $3x\div3\geq8\div3$ $x\geq2\frac{2}{3}$ In interval notation this is written as $[2\frac{2}{3},\infty)$ where [ indicates that the solution set for x includes $2\frac{2}{3}$.
