\[x >0.6\]

Answer 3

I skipped some steps but I hope it helps.

Answer 4

Okay, for the first one, we need the numbers on one side and the x's on the other. So we would move 19 to the other side to end up with -1.5<-2.5x We would then divide both sides by -2.5, and that would become 0.6>x. Notice the less than becomes a greater than when you divide by a negative number. The second one, we need to multiply first. We get 2q -q^2 -4+2q. This reduces to -q^2 + 4q - 4, or q^2 - 4q +4. This factors into (q-2)(q-2) < 0. I think you can go from there lol. (you just set each of the q-2's equal to 0). I hope this helps!! =)
