The correct statement is:
|9| > |−9|
This is true because the absolute value of 9 is 9 and the absolute value of -9 is also 9, so |9| = 9 and |−9| = 9. Therefore, |9| is equal to |−9|, making the statement take the form of "9 > 9", which is false!
Hence, the other statements should be analyzed as follows:
- |−9| ≠ |9|: False because |−9| = |9| = 9.
- |−8| > |−9|: False because |−8| = 8 and |−9| = 9, thus 8 is not greater than 9.
- |−9| > |−8|: False because |−9| = 9 and |−8| = 8, hence 9 is greater than 8.
So ultimately, none of the statements are true in terms of providing an inequality where one side is strictly greater or less than the other.
