MAT 222 week 2 DQ1

  

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. Reference the Discussion Forum Grading Rubric for guidance on how your discussion will be evaluated. 

     

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

Carefully review the Grading Rubric for the criteria that will be used to evaluate your discussion.
