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)
