Question

Can someone please check my answer?

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

x - 1 < -10 or x + 12 > 12

A number line with an open circle on -9, an open circle on 0, and shading in between.

x < -9 or x > 0

A number line with an open circle on -9, shading to the left, and an open circle on 0, shading to the right.

x > 0 or x < -9

My answer is x > 0 or x < -9

Is this right?

Answer 1

x - 1 < -10
x < -10 + 1
x < -9

x + 12 > 12
x > 12 - 12
x > 0

okay....we have x is less then -9 and greater then 0
The one that is not equivalent is : open circle on -9, open circle on 0, and shading in between.
