Josh determined the solution set to the following inequality. His work is shown below.
|36 β 4p| > 16
1.β(36 β 4p) > 16, β(36 β 4p) > 16
2.ββ4p > β20
ββp > 5
3.ββββββββ36 + 4p > 16
ββββββββ4p > 52
ββββββββp > 13
4.βp > 5 or p > 13
Analyze Joshβs work. Is he correct? If not, what was his mistake?
Yes, he is correct.
No. In step 1 his second inequality is not correct.
No. When solving the first inequality in step 2, he did not flip the inequality sign when he divided by a negative.
No. When solving the second inequality in step 3, he did not flip the inequality sign when dividing by a positive.
