Question

-5x-5<15

Solve the inequality and graph solution set. Write solution set in (a) set builder notation and (b) interval notation

Answer 1

1. -5x-5<15 [given]
2. -5x<20 [add 5 to both sides]
3. x>-4 [divide both sides by -5, don't forget to flip the inequality sign]

(a)

(b)
`(-4, \infty)`
