Below are sample questions representative of the exercises included on this worksheet and related ALG1.9 Inequality Symbols and Number Line Representation skill assessments:

Problem 1Difficulty: Mastery
Which answer best describes the solution set of 12 - 4x >= 0?
Aclosed circle at 3 with arrow left
Bopen circle at 3 with arrow left
Cclosed circle at 3 with arrow right
Dopen circle at 3 with arrow right
Solution & Explanation:Subtract 12 to get -4x >= -12. Divide by -4 and reverse the sign to get x <= 3, so the graph is closed at 3 and shaded left.
Problem 2Difficulty: Mastery
Which value satisfies -6 <= 2x - 4?
A-3
B-2
C-1
D-5
Solution & Explanation:Add 4 to both sides to get -2 <= 2x. Divide by 2 to get -1 <= x, so x >= -1. The value -1 works.
Problem 3Difficulty: Mastery
Use the number line graph shown to choose the solution to 2x + 1 < 0.
Ax < -0.5
Bx > -0.5
Cx <= -0.5
Dx >= -0.5
Solution & Explanation:Subtract 1 to get 2x < -1, then divide by 2. The solution is x < -0.5.
