In this discussion, you will be demonstrating your understanding of compound inequalities and the

effect that dividing by a negative has on an inequality. Read the following instructions in order and

view the example (available for download in your online classroom) to complete this discussion.

Please complete the following problems according to your assigned number. (Instructors will assign

each student their number.)

If your assigned

number is:

Your “and”

compound inequality is:

Your “or” compound

inequality is:

37 –9 < –1 + 4x < 15 8 – x > 15 or 6x – 13 > 11

•

• Solve the compound inequalities as demonstrated in Elementary and Intermediate Algebra and the

Instructor Guidance in the left navigation toolbar, in your online course. Be careful of how a

negative x-term is handled in the solving process. Show all math work arriving at the solutions.

• 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.

This is demonstrated in the Instructor Guidance in the left navigation toolbar, in your online

course.

• Incorporate the following five math vocabulary words into your discussion. Use bold font to

emphasize the words in your writing. Do not write definitions for the words; use them

appropriately in sentences describing your math work.

◦ Compound inequalities

◦ And

◦ Or

◦ Intersection

◦ Union

Your initial post should be at least 250 words in length. Support your claims with examples from

required material(s) and/or other scholarly resources, and properly cite any references. Respond to at

least two of your classmates’ posts by Day 7.
