($-\infty, -\frac{5}{2}]$

Work Step by Step

$Solve$ $the$ $linear$ $inequality$. $Express$ $the$ $solution$ $using$ $interval$ $notation$ $and$ $graph$ $the$ $solution$ $set$: $-4x \geq 10$ Solve for x $-4x \geq 10$ Divide both sides by -4 (Also switch the sign to less than equal) $\frac{-4x}{-4} \leq \frac{10}{-4}$ $x \leq -\frac{10}{4}$ $x \leq - \frac{5}{2}$ Express the solution in interval notation form ($-\infty, -\frac{5}{2}]$
