thank you!

Answer 3

The statement that is true about -9 is: **it is an integer but not a whole number**.

Here's a quick breakdown:

- **Integer**: The set of integers includes all whole numbers and their negative counterparts, so -9 is an integer.
- **Whole number**: Whole numbers are non-negative integers (0, 1, 2, 3, ...), so -9 is not a whole number.

The other options are false:
- -9 is not a whole number, so it cannot be both an integer and a whole number.
- -9 is rational because it can be expressed as a fraction (-9/1).

Answer 4

The correct answer is: **it is an integer but not a whole number.**
