and review the example of how to complete the math required for this
assignment:
 Use the properties of real numbers to simplify the following
expressions:

Evaluating Algebraic Expressions
Read the following instructions in order to complete this discussion, and
review the example of how to complete the math required for this
assignment:
1. Write your birth date or the birth date of someone in your family as
mm/dd/yy. (Example: March 13, 1981 is written 3/13/81, and
November 7, 1967 is written 11/7/67).
 Now let a = the one- or two-digit month number,
 b = the negative of the one- or two-digit day number, and
 c = the two-digit year number.
(Our example: a = 3, b = -13, and c = 81 or a = 11, b = -7, and c =
66)
1. Use the following algebraic expressions for parts c-d of the
discussion:



1. Evaluate the three given expressions using the a, b, and c from
your birth date. Make sure that b is negative when you plug in the
values.
2. After you have your math worked out on scratch paper, post your
results as well as a description of the steps you took to evaluate the
expressions.
 Did you notice anything interesting about the results of and ?
Was this coincidence or do you think there is a reason for this?

week's Assignment link in the left navigation.
Inequalities
Read the following instructions in order to complete this assignment,
and review the exampleow to complete the math required for this
assignment:

mentions:
o 17 < BMI < 22 might have a longer life span than average
o 23 < BMI < 25 probably not overweight
o 25 < BMI < 29.9 probably overweight
o BMI > 30 obese
You will use your height to plug into the formula to solve for W, the
weight range that will go with each category. You may prefer to solve
the formula for the variable W before plugging in values, which is fine.

reasons why they could be misleading
o An evaluation of the regions outside of the “probably not
overweight” range using both set notation and interval
notation. Include a simple graph of the regions. (See
Instructor Guidance example for some ideas of how to do
this.)
o The incorporation of 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

assignment:
1. Think of something you want or need for which you currently do
