Question

The number 5 is included in which of the following solutions? Choose all that apply

{x:x <-3 or >4}

{x:x ≥5}

{x:x <5}

{x:0

Answer 1

Option 1 and 2 are correct.

Explanation:

1. {x:x <-3 or >4}

Here the values of x can be less than -3 or the values of x can be greater than 4. Since 5 is greater than 4 so, 5 is included in the solution

2. {x:x ≥5}

Here the values of x can be greater than or equal to 5. So, 5 is included in the solution.

3. {x:x <5}

Here the values of x can be less than 5. So, 5 is not included in the solution

4. {x:0<x<4}

Here the value of x is greater than 0 but less than 4. So, 5 is not included in the solution

So, Option 1 and 2 are correct.
