One-Variable Compound Inequalities

Order Instructions

1. Be careful how a negative x-term is handled in the solving process. Show all math work arriving at the solutions.

2. Describe in words what the solution sets mean, and then display a simple line graph for each solution set.

3. Incorporate the following vocabulary terms; you must use all of them

Compound inequalities

And

Or

Intersection

Union

4. Show the solution sets written algebraically and as a union or intersection of intervals. Describe in words what the solution sets mean, and then display a simple line graph for each solution set.

Each math problem should be solved and described separately.

1. (Your “and” compound inequality is) –9 < –1 + 4x < 15

2. (Your “or” compound inequality is:) 8 – x > 15 or 6x – 13 > 11
