Question

2. Solve for z and express your answer in interval notation: 10 – 4z<20

Answer 1

I belive its z > -5/2

Explanation:

First subtract 10 from both sides.

Then simplify

Then multiply both sides by -1 because you're reversing the inequality

simplify again

Then divide both sides by 4

Finally you simplify to get

z > -5/2
