Write a compound inequality for the graph shown below calculator

What is compound inequality?

Two statements are connected by using the word ” or” or by the word “and” is a sentence for compound inequality.

The word ” and” are used to connect the statements, then the compound sentence of both statements are true and the word ” and ” is also known as Conjunction.

The word “or” is used to connect the statements, if at least one statement is true then the compound sentence is true and the word “or” is known as Disjunction.

How Does Graphing Inequalities Calculator Work?

Suppose we want to solve a linear inequality. The general form of a linear equation in two variables is given by ax + by = c. Now the same equation can be represented as an inequality by replacing the "=" sign with the required inequality sign. Given below are the steps that can be used to graph such an inequality.

• Step 1: Irrespective of the inequality sign, we will first solve the linear inequality in the same way as we solve a linear equation.
• Step 2: The variable y will be to the left-hand side (L.H.S) of the equation. The rest of the terms will be shifted to the right-hand side (R.H.S).
• Step 3: Identify certain test points. This implies that we have to substitute the value of x with certain numbers and find the corresponding value of y.
• Step 4: Now we draw a straight line that passes through these test points on a graph.
• Step 5: Take the inequality into consideration and shade the required region. Shade above the line for a "greater than" inequality and below the line for a "lesser than" inequality. The shaded region contains all coordinates that can solve the inequality.

Similar steps can be used to solve other inequalities such as quadratic, cubic, etc.

Solved Examples on Graphing Inequalities Calculator

Example 1:

Compute the graph for 2x + 3y ≤ 7 and verify it using the graphing inequalities calculator.

Solution:

Solving the inequality as an equation

2x + 3y = 7.

y = -(2/3)x + 7/3

x = 2, y = 1.

x = 5, y = -1

x = -7, y = 7.

Draw a line passing through these points on the graph.

As we have a "lesser than" inequality, we shade the region below the line.

Example 2:

Compute the graph for y > -5x + 2 and verify it using the graphing inequalities calculator.

Solution:

Solving the inequality as an equation

y = -5x + 2

x = 0, y = 2.

x = 1, y = -3

x = -1, y = 7.

Draw a line passing through these points on the graph.

As we have a "greater than" inequality, we shade the region above the line.

Similarly, you can try the graphing inequalities calculator to compute the graph for the following inequalities:

• y ≤ 2x + 5
• y > 5x2 - 5
