create a graph on the number line for each statement and you see that one of these isn't a compound inequality.

I cant open, the attachment

Answer 6

@satellite73 those were the answers I got, if that's the question you're asking.

Answer 7

x + 6 <= 11
x <= 11 - 6
x <= 5

x + 16 >= 3
x >= 3 - 16
x > = - 13

The last one is incorrect

Answer 8

any questions ?

Answer 9

your last answer choice is saying a number line with a closed circle on -13(this part is true), however, it also says shading to the left.(wrong)
less then means shading to the left, and greater then means shading to the right. The answer is x >= -13, that says greater, meaning shading to the right, not the left.
