Question

Choose the correct description of the graph of the compound inequality

x − 1 less than or equal to 9 or 2x greater than or equal to 24

A. A number line with an open circle on 10, shading to the left, and an open circle on 12, shading to the right

B. A number line with an open circle on 10, an open circle on 12, and shading in between

C. A number line with a closed circle on 10, a closed circle on 12, and shading in between

D. A number line with a closed circle on 10, shading to the left, and a closed circle on 12, shading to the right

Answer 1

D

Explanation:

Simple answer

Answer 2

x - 1 < = 9
x < = 9 + 1
x < = 10

2x > = 24
x > = 24/2
x > = 12

ok...since they both include equal signs, they will both have closed circles.
closed circle on 10, shaded to the left (because it is less then)...and a closed circle on 12, shaded to the right (because it is greater then)
