#### Solutions

Chapter 1, Problem 93RE
To determine

## To calculate: The solution of the given inequality and express the solution using interval notation. Also graph the solution set on the real number line.

Expert Solution

In order to solve an inequality, the following things can be done.

• Add the same number to each side of the inequality.

• Subtract the same number from each side .

• Multiply or divide each side by the same number and if multiplied or divided each side by a negative number, then the inequality symbol must be reversed.

The inequality can be solved as follows:

|x5|3

(x5)3x530x80x8

And

|x5|3

(x5)3x+530x+20x2

The solution using interval notation is [2,8]

The shaded region shows solution of the given inequality on the graph below .

### Explanation of Solution

Given information:

The given inequality is |x5|3

Formula used:

In order to solve an inequality, the following things can be done.

• Add the same quantity to each side of th inequality

• Subtract the same quantity from each side

• Multiply or divide each side by the same positive quantity and If multiplied or divided each side by a negative quantity, then the inequality symbol must be reversed.

In case of non linear inequality,the function may be factorised and solved further long division method etc.
