Question 855920
When you multiply or divide both sides of an inequality by a negative number, the inequality sign will flip.



So you will go from {{{-3r>15}}} to {{{r < -5}}} after you divide both sides by -3. Notice how the <font size=8 color="red">></font> changes to <font size=8 color="red"><</font>




So the answer is {{{r < -5}}}. This means you'll have an open circle at -5 and shading to the left.
