  • There are two basic approaches to solving absolute value inequalities: graphical and algebraic. The advantage of the graphical approach is we can read the solution by interpreting the graphs of two equations. The advantage of the algebraic approach is that solutions are exact, as precise solutions are sometimes difficult to read from a graph.

In Unit 4, seventh-grade students continue to build on the last two units by solving equations and inequalities with rational numbers. They use familiar tape diagrams as a way to visually model situations in the form px + q = r and p(x + q) = r. These tape diagrams offer a pathway to solving equations using arithmetic, which students compare to a different approach of solving equations algebraically.

    Inequality is a relationship between two expressions. These inequalities have "greater than," "less than," "greater than or equal to," or "less than or equal to," signs in place of a simple "equals to" sign. You can solve inequalities just as you solve algebraic equations. Linear inequalities are where the highest power on the variable is 1.To graph the inequality y = -x + 6, we first graph the equation y = -x + 6 shown in Figure 7.13. Notice that (3, 3), (3, 2), (3, 1), (3, 0), and so on, associated with the points that are on or below the line, are all solutions of the inequality y = -x + 6, whereas (3,4), (3, 5), and (3,6), associated with points above the line are not solutions of the inequality.

Toon University: Comparing Number Values Game To solve an inequality in one unknown graphically, it is necessary to transfer all its terms to the same part, i.e. to reduce it to the shape: f (x) > 0, and to build a graph of the function y = f (x). After this, using the built graph, it is possible to find zeros of the function (see above), which divide an x -axis into some intervals.

    This is very similar to solving systems of equations, topic 3.The only difference is that the equal sign will be changed to an inequality sign. Instead of looking for a specific point of intersection as our answer, we will be looking for a region (area) of the graph that gives all of the points that will make the system of inequalities true.

To solve a rational equation, multiply each term on both sides by the LCD of all the denominators in the equation. Then solve the resulting equation, which has no fractions. Always check for extraneous solutions – values that make one or more of the denominators equal to 0. Chapter 6: Systems of Linear Equations & Inequalities Unit 2 introduces the student to the linear functions and their real-life applications.

    A system of equations is a set of equations with the same variables. A system of inequalities is almost exactly the same, except you're working with inequalities instead of equations! To solve such a system, you need to find the variable values that will make each inequality true at the same time. Graphing linear inequalities When you are graphing inequalities, you will graph the ordinary linear functions just like we done before. The difference is that the solution to the inequality is not the drawn line but the area of the coordinate plane that satisfies the inequality.
