Answer
\( x - 9 \) can be read as " \( x \) minus 9" or as "the distance between \( x \) and 9."
Solution
The statement describes the expression \( x - 9 \) in two different ways. Let's break it down:
1. **Mathematical Interpretation**:
- The expression \( x - 9 \) is read as " \( x \) minus 9." This is a straightforward arithmetic operation where you subtract 9 from the variable \( x \).
2. **Geometric Interpretation**:
- The phrase "the distance between \( x \) and 9" refers to the absolute value of the difference between \( x \) and 9. In mathematical terms, this can be expressed as \( |x - 9| \).
Thus, the two interpretations of \( x - 9 \) are:
- As an arithmetic operation: \( x - 9 \)
- As a distance: \( |x - 9| \)

Simplify this solution Beyond the Answer
The expression \( x-9 \) can also be interpreted in math as the distance between the value \( x \) and the number 9 on a number line. If \( x \) is greater than 9, the result will be positive, while if \( x \) is less than 9, the result will be negative, showcasing how subtraction relates to their relative positions. In practical scenarios, understanding subtraction this way is crucial! For example, when calculating how far someone is from a specific point, knowing whether \( x \) is ahead or behind can change your route or strategy completely. Subtraction isn't just a number game; it's all about context!
