In mathematics a linear inequality is **an inequality which involves a linear function**. A linear inequality contains one of the symbols of inequality:. It shows the data which is not equal in graph form. < less than.

## What is linear equality and inequality?

A linear inequality resembles in form an equation, but with the equal sign replaced by an inequality symbol. The solution of a linear inequality is generally a range of values, rather than one specific value. Such inequalities arise naturally in problems involving words such as ‘at least’ or ‘at most’.

## What are the types of linear inequalities?

There are Four Types of Inequalities, They are:

- Strict: The inequalities that have < or > symbol between the L.H.S and R.H.S.
- Slack: The inequalities that have ≤ or ≥ symbol between the L.H.S and R.H.S.
- Linear: The inequalities that have a degree 1. Example, 5x + 2y>10.
- Quadratic: The inequalities that have a degree 2.

## What is an example of a linear inequality?

What Is an Example of Linear Inequality? An example of linear inequality is x – 5 > 3x – 10. Here, the LHS is strictly greater than the RHS since greater than symbol is used in this inequality. After solving, the inequality looks like this: 2x > 5 ⇒ x > (5/2).

## What is the difference between linear equation and linear inequality?

The only difference between the two equations is that a linear equation gives a line graph. In contrast, a linear inequality shows the area of the coordinate plane that satisfies the inequality. Given an inequality equation, make y the subject of the formula. For example, y > x + 2.

## Why it is important to understand linear inequalities?

Inequalities are critical in prediction of future results. You know an upper limit, but can’t predict where below that upper limit actual results will fall. Using the upper limit as the boundary, and solving the inequality can give you an idea of what may happen, though without certainty.

## Who discovered linear inequalities?

Inequalities. The signs for greater than (>) and less than (<) were introduced in 1631 in “Artis Analyticae Praxis ad Aequationes Algebraicas Resolvendas.” The book was the work of British mathematician, Thomas Harriot, and was published 10 years after his death in 1621.

## What are the different types of inequalities in math?

An inequality is a mathematical relationship between two expressions and is represented using one of the following:

- ≤: “less than or equal to”
- <: "less than"
- ≠: “not equal to”
- >: “greater than”
- ≥: “greater than or equal to”

## What is linear inequality one variable?

DEFINITION. Definition: A linear inequality is an inequality in one variable that can be written in one of the following forms where a and b are real numbers and a≠0 a ≠ 0: a+bx<0 a + b x < 0; a+bx≤0 a + b x ≤ 0; a+bx>0 a + b x > 0; a+bx≥0.

## How do you simplify a linear inequality?

Solving single linear inequalities follow pretty much the same process for solving linear equations. We will simplify both sides, get all the terms with the variable on one side and the numbers on the other side, and then multiply/ divide both sides by the coefficient of the variable to get the solution.

## Are there examples of linear inequalities that have only one solution?

Linear inequalities can either have no solution, one specific solution, or an infinite amount of solutions. Thus, the total possible would equal three. For instance, say we have a variable x. Although we do not know what x is, we can determine it’s value depending on what inequalities it has been placed next to.
