Question

Choose the correct description of the graph of the compound inequality

x−3<−9 or x+5≥12


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

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

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

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

Answer 1

x - 3 < - 9 -- add 3 to both sides
x < -9 + 3
x < - 6

x + 5 >= 12 -- subtract 5 from both sides
x >= 12 - 5
x >= 7

open circle if there is no equal sign
closed circle if there is an equal sign
(<) less then means shading to the left
(>) greater then means shading to the right

So what do you think is the answer ?
