Choose the correct description of the graph of the compound inequality: (5 points)
skad [1K]

Answer:

D

Step-by-step explanation:

Firstly,  

≤  or  ≥  means closed circle, and

<   or >  means open circle

Now, let's solve the compound inequality:

x - 1 ≤ 7

x ≤ 8

and

2x ≥ 22

x ≥ 11

This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"

Looking at the choices, D is right.
