One-Variable Compound Inequalities

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 examplePreview the documentView in a new window(available for download in your online classroom) to complete this discussion. Please complete the following problems according to your assigned number.

 

My Assigned Number is: 29, below are the equations associated.

 

Your “and” compound  inequality is:

–16 ≤ 2 + 9x ≤ 11

 

Your “or” compound inequality is:

12 – x > 15   or   4x – 13 > 7

 

  • 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.
