Question

Solve the inequality  and write the solution set in interval notation.

Quizplus · Accepted Answer

To solve the inequality, first subtract 7 from both sides:
$-2e > -9$
Then, divide both sides by $-2$, remembering to flip the inequality sign since we are dividing by a negative number:
$e < 4.5$
The solution set in interval notation is $(-\infty, 4.5)$. 
Choice D matches this solution set.
