Question

Which of the following is not an equivalent form of the compound inequality

x - 1 < -11 or x + 12 > 14

A number line with an open circle on -10, an open circle on 2, and shading in between.

x < -10 or x > 2

A number line with an open circle on -10, shading to the left, and an open circle on 2, shading to the right.

x > 2 or x < -10

Answer 1

Answer 2

x - 1 < -11

x < -11+1

x < -10

So this suggests that we shade to the left of -10 and not to the right of -10

Answer 3

So there's no way to shade in between -10 and 2 if you're actually shading to the left of -10 (and not to the right)

Answer 4

Do you see what I'm saying?

Answer 5

between B and D????

Answer 6

@jim_thompson5910

Answer 7

no it's actually A because choice A says to shade between, but you can't shade between if you're not shading to the right of -10

Answer 8

ohh so its A :) thanks
