Answer

$n\geq1\frac{1}{4}$
1502719541

Work Step by Step

$n-\frac{1}{2}\geq\frac{3}{4}\longrightarrow$ add $\frac{1}{2}$ to each side $n-\frac{1}{2}+\frac{1}{2}\geq\frac{3}{4}+\frac{1}{2}\longrightarrow$ add $n\geq1\frac{1}{4}$ A closed dot at the endpoint will indicate that $1\frac{1}{4}$ is part of the solution set. Since the variable is greater than the endpoint, the arrow will continue to the right in the direction of increasing value.
