Question

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

x + 6 < 12 or x + 6 13

x < 6 or x 7

A number line with an open circle on 6, a closed circle on 7, and shading in between.

x 7 or x < 6

A number line with an open circle on 6, shading to the left, and a closed circle on 7, shading to the right.

Answer 1

its x+6< 12 or x + -6 is greater then or equal to 13

Answer 2

and the answer A is x<6 or x is greater or less then 7

Answer 3

I'm going to assume you mean x+6 < 12 or x+6 >= 13. One thing you could do is subtract 6 from both sides of both inequalities, to get x < 6 or x >= 7. Looks like that's your first option. When you graph that, you get something like this: which looks like you fourth option. If your third option is x >= 7 or x <6, that's just the first option reordered, so that works too.
