Explanation of Solution

Given information:

The inequality x5 .

Formula used:

The notation of number line shows the given interval [) shows that closed and a open interval.

Calculation:

It is provided that the notation x5 . It means [5,) ,shows that the real numbers are here starting form 5 and endless it means all real numbers upto 5..

So the interval is , {xR\5x} .

This is the written statement of this notation and here x is a member of family of real numbers such that x is a number of the interval x5 ..

Also this equation is written as: {xR\x[5,)} .

The notation of these inequalities are here:
