Ashford 3: - Week 2 - Discussion 1

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.

## 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 theexampleto complete this discussion:
• According to the first letter of your last name, find the pair of compound inequalities assigned to you in the table below.

 If the first letter of your last name is Your “and” compound inequality is Your “or” compound inequality is A or L -4 ? 3 + 7x < 24 5 – x ? 7 or 8x – 3 > 29 B or K -16 ? 2 + 9x ? 11 12 – x > 15 or 4x – 13 > 7 C or J -10 < -2 + 8x < 22 4x + 7 < 11 or 1 – x ? -2 D or I -17 < 3 + 10x ? 33 5x + 3 ? -2 or 13 – x ? 6 E or H -1 ? -3 + 2x < 17 7 – x ? 6 or 7x – 1 > 27 F or G -12 < 12 + 4x < 0 12 – x > 15 or 7x – 13 > 1 M or Z -1 ? 3 + 2x < 11 1 – x ? -3 or 5x – 1 > 19 N or Y -1 < 4 + 5x ? 19 2x + 3 ? -1 or 10 – x ? 5 O or X -4 ? 5 + 3x ? 11 2x + 2 < 2 or 3 – x ? 0 P or W -9 < -1 + 4x < 15 8 – x > 15 or 6x – 13 > 11 Q or V -10 < -3 + x ? 21 2 – x ? 1 or 6x – 1 > 17 R or U -11 ? -5 + 6x < 13 3x + 2 ? -1 or 11 – x ? 4 S or T 0 ? 4 + 2x ? 22 3x + 6 < -3 or 5 – x ? 1
• Solve the compound inequalities as demonstrated inElementary and Intermediate Algebraand the Instructor Guidance in the left navigation toolbar, being 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 as demonstrated in the Instructor Guidance in the left navigation toolbar.

• Incorporate the following five math vocabulary words into your discussion.Usebold 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.

Two-Variable Inequalities

Read the following instructions to complete this assignment:
1. Solve problem 68 on page 539 of Elementary and Intermediate Algebra, and make sure to study the given graph. For the purposes of the assignment, it would be helpful to copy the graph onto your own scratch paper.

2. Write a two- to three-page paper (not including the title page) that is formatted in APA style and according to theMath Writing Guide. Format your math work as shown in theexample, and be concise in your reasoning. In the body of your essay, do the following:

• Demonstrate your solution to all three portions of the above problem, making sure to include all mathematical work, and an explanation for each step.

• Use the inequality you create from part (a) of problem 68 to evaluate the following two scenarios:
• The Burbank Buy More store is going to make an order which will include, at most, 60 refrigerators. What is the maximum number of TVs that could also be delivered on the same 18-wheeler? Be sure to show all your work and how you came to that conclusion.
• The next day, the Burbank Buy More decides they will have a television sale so they change their order to include at least 200 TVs. What is the maximum number of refrigerators that could also be delivered in the same truck? Be sure to show your work and how you came to that conclusion.

3. Incorporate the following five math vocabulary words into your discussion. Useboldfont to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing your math work.):
• Solid line
• Dashed line
• Parallel
• Linear inequality
• Test point
