# Writing absolute value inequalities from a word problem

Read the inequality as a "distance from 0" statement 2. The trick is to understand the meaning of absolute value in terms of distance. How can you represent the absolute value of an unknown number. Keep these handy as a reference. Should you use absolute value symbols to show the solutions.

So the whole piecewise function is: Model using simple absolute value inequalities to represent constraints or limits on quantities such as the one described in the second problem.

Shmoop will lay out the 7 magic steps that will make deciphering word problems an alge—breeze. Remember data and solve problem in your dream Remember data and solve problem in your dream creative writing in english, emerson clothing line.

The type of inequality sign in the problem will tell us how to set up the compound inequality. Are you ready to try some on your own now. Click here to move onto the word problem practice problems.

It develops algebraic fluency by providing students with the skills needed to solve equations and perform important manipulations with numbers, variables, equations, and inequalities. Provide additional opportunities for the student to write and solve absolute value equations.

The student does not understand how to write and solve absolute value inequalities. Multi step equation word problems worksheet explanatory writing examples life without electricity essay melaleuca overview fluid mechanics topics reflective journal template for teachers product launch plan template free.

Since this process is not dependent upon the expression inside the absolute value symbols, we can apply it to the following example. Choose the appropriate functional representation to model a real world situation and solve problems relating to that situation.

The answer to this case is always all real numbers. Set up a compound inequality The inequality sign in our problem is a less than sign, so we will set up a 3-part inequality: Equation and inequalities in one and two variables Linear system of equations and inequalities Represent functions linear and non-linear in multiple ways, including tables, algebraic rules, graphs, and contextual situations and make connections among these representations.

Examples of Student Work at this Level The student correctly writes and solves the absolute value inequality described in the first problem.

Since distance cannot be less than a negative there is no solution. Write the equation or inequality. How did you solve the first absolute value inequality you wrote.

Provide additional examples of absolute value inequalities and ask the student to solve them. Why is it necessary to use absolute value symbols to represent the difference that is described in the second problem.

This is one of the reasons why we read the problem so much in Step 1 and identify the unknowns in Step 2. Remove the absolute value bars by setting up a compound inequality.

The main unifying themes of the course include understanding, writing, solving, and graphing linear equations, systems of linear equations and inequalities, quadratic equations, and rational equations. You might want to review Solving Absolute Value Equations and Inequalities before continuing on to this topic.

For each problem, write an absolute value equation and two inequalities that can be solved using the given graph. Then, solve, write the solution set in set-builder notation, and graph the solution.

Solve an absolute value equation using the following steps: Get the absolve value expression by itself.

Set up two equations and solve them separately. Solving compound inequalities A compound inequality contains at least two inequalities that are separated by either "and" or "or".

The graph of a compound inequality with an "and" represents the intersection of the graph of the inequalities.
