# How to write an absolute value equation with given solutions day spa

Are you ready to dive into the "real world" of inequalities? I know that solving word problems in Algebra is probably not your favorite, but there's no point in learning the skill if you don't apply it. I promise to make this as easy as possible. Pay close attention to the key words given below, as this will help you to write the inequality. Problem 23a - 23c: The bar graph below shows the profit a cd store made over the months of September through December of last year. Use the graph to answer questions 23a - 23c. About how much was the profit in December?

The bar that associates with December is the fourth bar from the left. The top of that bar is in between 20 and 25 on the vertical axis. A good approximation is Which month had the lowest profit?

It looks like October had the lowest profit. What is the sum of the profits of October and November? The bar that associates with October is the second bar from the left.

The top of that bar matches with 5 on the vertical axis.

The bar that associates with November is the third bar from the left. The top of that bar matches with 10 on the vertical axis. Problems 24a - 24b: The line graph below shows last week's high temperatures in Fahrenheit. Use the graph to answer questions 24a - 24b. How much was Monday's high temperature? The point that matches with Monday on the horizontal axis also matches 85 on the vertical axis.

Monday's high temperature was 85 degrees Fahrenheit. Which day had the highest high temperature? It looks like Wednesday had the highest high temperature.Whatever the value of x might be, taking the absolute value of x makes it positive.

## Example 2: Standard Form Equations

Since x might originally have been positive and might originally have been negative, I must acknowledge this fact when I remove the absolute-value bars.

I do this by splitting the equation into two cases. All day, an equation such as that will not have any solutions since an absolute expression can NEVER be 0 Work backwards: You want the right side to be 5 or 15, so you can envision having 5 on the right side, which will become 15, or 5.

Dec 30,  · Then I had students practice writing absolute value inequalities when given a graph and practice finding the midpoint of the graph and distance from the midpoint when given an absolute value .
