How to graph compound inequalities. The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. The graph of a compound inequality with an and represents the intersection of the graph of the inequalities. Inequality solve compound Algebra.

Trying to solve a compound inequality. Looking at the graph shows us that what we have is an or compound inequality because the two arrows are going in opposite directions. We then get x.

This union is worked out as two separate inequalities and then graphed on a common number line. Now click the button Solve to get the inequality. Unions When an inequality is combined by the word or the compound inequality is formed.

To better understand how to graph inequalities look at the examples below or experiment with the grapher that is immediately below. How To Graph Compound Inequalities. When solving compound inequalities we use some of the same methods used in solving multi-step inequalities.

The solution is that portion of the graph. A compound inequality contains at least two inequalities that are separated by either and or or. A number is a solution to the compound inequality if the number is a solution to both inequalities.

How Do You Graph the Intersection of Two Inequalities. A compound inequality is an inequality that is formed by the union or or the intersection and of two simple inequalities. 35 Votes The graph of a compound inequality with an and represents the intersection of the graph of the inequalities.

Inequality Number Line Grapher X Type of inequality Label the number line Label First Last Point Label First Last Zero Point Label All Width Examples Example 1 Example 2 This Page. Putting the two graphs together gives the following. When the word that connects both inequalities is or the solution is any number that makes either inequalities true.

Math video on how to solve and graph compound inequalities with two inequality signs of an and. The graphs for x 2 and x 4 should look like this. There are two types of compound inequalities.

2 x 5 and -1 2 x In the first equation 2 x 5 we need to subtract 2 from each side to get the variable by itself. To solve a compound inequality first separate it into two inequalities. Then solve both inequalities and graph.

The solutions to compound inequalities can be graphed on a number line and can be expressed as intervals. The graph has an open circle on 6 and a blue arrow to the right and another open circle at 2 and a red arrow to the left. When a compound inequality is written without the expressed word and or or it is understood to automatically be the word and Reading x 3 x 4 from the x position you say reading to the left x is greater than 3 and reading to the right x is less than 4 The graph of the solution set is shown in Figure 1.

Lets graph the compound inequality 6 m 8 7 8 6 o o 2 Which is equivalent to -3 y 5. For compound inequalities mathematical operations must be applied to all sides of the inequality left right and middle and division or multiplication by negatives reverses the direction of the sign. Determine whether the answer should be a union of sets or or an intersection of sets and.

You can show this graphically by putting the graphs of each inequality together on the same number line. This tutorial will take you through the process of splitting the compound inequality into two inequalities. A number is a solution to the compound inequality if the number is a solution to both inequalities.

Number lines help make graphing the intersection of two inequalities a breeze. This tutorial shows you how to graph two inequalities on the same number line and then find the intersection. X 2 and x 4.

For example graph the following compound inequality. Enter two inequality equations in the respective input field. 1 Solve each part of the inequality separately.

-5 x 1 -5 x 1 -5 x 1 -5 x 1 Writing Compound Inequalities All real numbers that are greater than 2 and less than 6 All real numbers that are less than 0 or greater than or equal to 5 - 2. Finally the inequality equation with the number line will be. The graph of a conjunction is typically a line segment on the number line.

The procedure to use the compound inequality calculator is as follows. It can either be written as x -1 and x 2 or as -1 x 2. That means that numbers bigger than 5 or ones smaller than -5.

If it is unclear whether the inequality is a union of sets or an intersection of sets then test each region to see if it satisfies the compound inequality. It can either be written as x -1 and x 2 or as -1 x 2. Y -3 or y 5 y -3 and y 5 y -3 or y 5 y -3 and y 5 3 Which is equivalent to x -5 and x 1.
