Question
In Exercises $1-4,$ make the given changes in the indicated examples of this section and then perform the indicated operations.In Example $7,$ change the inequality to $-2>-4$ and then perform the two operations shown in color.
Step 1
We multiply both sides by -3. Remember, when we multiply or divide an inequality by a negative number, we must reverse the inequality sign. So, $-2*-3 < -4*-3$ becomes $6<12$. Show more…
