Write the following set as an interval using interval notation.

{x|7<x≤9}

The set \(\{x \mid 7 < x \leq 9\}\) in interval notation is:

\((7, 9]\)

This represents all values of \(x\) that are greater than 7 but less than or equal to 9.

Would you like more details on how interval notation works, or do you have any other questions?

Here are five related questions:
1. How do you write the set \(\{x \mid 3 \leq x < 8\}\) in interval notation?
2. What does the interval \([2, 6)\) represent on a number line?
3. How do you represent the set of all real numbers less than or equal to 5 using interval notation?
4. What is the interval notation for the set \(\{x \mid -4 < x < 1\}\)?
5. How do you express the union of two intervals, such as \((2, 5]\) and \([6, 9)\)?

**Tip**: Square brackets \([ ]\) in interval notation indicate that the endpoint is included, while parentheses \(( )\) indicate that it is not.
