Rewrite these inequalities in interval notation. At least 3,000, but less than30,000:A. 3,000 21 > 30,000B. 3,000 < 1 530,000C.3,000 si < 30,000O D.D. 3,000 SIS 30,000

Answer 1

We were told to re-write the inequalities in interval notation. To do this, let us split the statement

First of all, let us represent the number within the range with x

So that

If the number is at least 3000 then it means that the minimum value of x is 3000

This is represented as

`\begin{gathered} x\ge3000 \\ x\text{ is greater than or equal to 3000} \end{gathered}`

For the second statement

The number is less than 30000

This means that the number is less than 30000, it can be represented by

`x<30000`

If we combine the two mathematical statements we will have

`3000\le x<30000`
