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

x + 18 ≤ 11 and x + 18 ≥ 3

A number line with a closed circle on -15, shading to the left, and a closed circle on -7, shading to the right.

11 ≥ x + 18 ≥ 3

-7 ≥ x ≥ -15

A number line with a closed circle on -15, a closed circle on -7, and shading in between.

My answer is -7 ≥ x ≥ -15

Am I right?

unfortunately you are incorrect

jim_thompson5910 · Answer

they want something that isn't equivalent

anonymous · Answer

Oh then it would be A number line with a closed circle on -15, a closed circle on -7, and shading in between. Right?

jim_thompson5910 · Answer

but that's the graph of -7 ≥ x ≥ -15 or  -15 ≤ x ≤ -7

anonymous · Answer

Oh ok hold on

anonymous · Answer

11 ≥ x + 18 ≥ 3
