When you are working with Algebra you have to be able to understand this section, inequality in a greater depth when we are using equivalent numbers. “Inequalities occur in applications, just as equations do. Certain verbal phrases indicate inequalities.” (Dugopolski, 2012). I will be using symbols to express the inequality and also their meanings. I will also be displaying my solutions to four separate formulas that are used in different equalities; I will also include my work while doing it. I will be using five vocabulary words that will help me in finding the solutions to each problem.

For this weeks topic we are discussing BMI formulas. This formula uses a persons BMI, Body Mass Index. I will have many separate formulas that show how their BMI could be an Inequality or Inequalities. I will also be showing my work that will demonstrate solutions to many formulas. A person can have a lesser BMI or a greater BMI, I will also chose one to make a graph. I will also be including more than one Inequality and also showing a Compound Inequality. Last but not least I will be showing an example if the said formula is an Inequality or Inequalities and how said region can be expressed using set notation and Interval notation.

When looking at the BMI chart, it showed the formula for BMI or Body Mass Index:

BMI= 703W

H2

W= ones weight in pounds

H= Ones height in inches

Here are the four formulas I will be discussing and their meaning using a BMI chart:

* 17<BMI<= 22 might have a longer life span then average

* 23<BMI<= 25 probably not overweight

* 25<BMI<= 30 probably overweight

* BMI>30 Obese

Using my own height I then calculated four separate Intervals, my height is 71 inches.

The first Interval shows that I might have a longer life span than the average person. Here is the Compound Inequality for this equation:...
