Question

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

x - 1 < -12 or x + 12 > 10
Answer
x < -11 or x > -2
A number line with an open circle on -11, shading to the left, and an open circle on -2, shading to the right.
x > -2 or x < -11
A number line with an open circle on -11, an open circle on -2, and shading in between.

Answer 1

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


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


x < -11 or x > -2


So choice A is out the question

-------------------------------------------------------


This graphs to "A number line with an open circle on -11, shading to the left, and an open circle on -2, shading to the right.", so choice B is out


-------------------------------------------------------


choice C is just a flip of choice A, so thats out too


So the answer is choice D by process of elimination

Answer 2

Choose the correct description of the graph of the compound inequality

x - 3 < -11 or x + 5 14
Answer
A number line with a closed circle on -8, an open circle on 9, and shading in between.
A number line with a closed circle on -8, shading to the left, and an open circle on 9, shading to the right.
A number line with an open circle on -8, a closed circle on 9, and shading in between.
A number line with an open circle on -8, shading to the left, and a closed circle on 9, shading to the right.

Answer 3

missing a sign...please give me a sign lol

Answer 4

> or <

Answer 5

mhm >=

Answer 6

k thx

Answer 7

lol sorry agian..

Answer 8

x - 3 < -11 or x + 5 >= 14


x < -11+3 or x >= 14-5


x < -8 or x >= 9


So we have an open circle at -8 and we shade to the left

then we have a closed circle at 9 and we shade to the right


so choice D is the answer

Answer 9

lol it's ok
