Application of Linear Inequation:Temperature Range

 Post to:   Explanation:

Linear inequality

In mathematics a linear inequality is an inequality which involves a linear function.

## Linear inequalities in real numbers

### Definitions

When two expressions are connected by 'greater than' or 'less than' sign, we get an inequation.

When operating in terms of real numbers, linear inequalities are the ones written in the forms or ,��

where f(x) is a linear functional in real numbers and b is a constant real number.

The above are commonly written out as or Sometimes they may be written out in the forms or Here are called the unknowns, are called the coefficients, and b is the constant term.

A linear inequality looks exactly like a linear equation, with the inequality sign replacing the equality sign. (Our solved example in mathguru.com uses this concept)
