Describe All Numbers That Are At A Distance Of 6 From The Number 5. Express This Using Absolute Value Notation.
===========================================================
Introduction
In mathematics, the concept of distance between two numbers is crucial in various mathematical operations and calculations. The absolute value notation is a powerful tool used to represent the distance between two numbers. In this article, we will explore the numbers that are at a distance of 6 from the number 5, using absolute value notation.
Understanding Absolute Value Notation
Absolute value notation is a mathematical representation of the distance between two numbers. It is denoted by the symbol |x|, where x is the number. The absolute value of a number is its distance from zero on the number line. For example, the absolute value of 5 is |5| = 5, and the absolute value of -5 is | -5 | = 5.
Numbers at a Distance of 6 from 5
To find the numbers that are at a distance of 6 from the number 5, we can use the absolute value notation. We can represent this as |x - 5| = 6, where x is the number we are looking for.
Solving the Equation
To solve the equation |x - 5| = 6, we need to consider two cases:
Case 1: x - 5 ≥ 0
In this case, we can rewrite the equation as x - 5 = 6. Solving for x, we get x = 11.
Case 2: x - 5 < 0
In this case, we can rewrite the equation as -(x - 5) = 6. Simplifying, we get -x + 5 = 6. Solving for x, we get x = -1.
Conclusion
In conclusion, the numbers that are at a distance of 6 from the number 5 are 11 and -1. These numbers can be represented using absolute value notation as |x - 5| = 6.
Examples
Here are some examples of numbers that are at a distance of 6 from the number 5:
- 11: |11 - 5| = 6
- -1: |-1 - 5| = 6
- 17: |17 - 5| = 12 (not 6)
- -7: |-7 - 5| = 12 (not 6)
Applications
The concept of numbers at a distance of 6 from the number 5 has various applications in mathematics and real-world scenarios. For example:
- In geometry, the concept of distance between two points is crucial in calculating the length of a line segment.
- In algebra, the concept of absolute value notation is used to solve equations and inequalities.
- In real-world scenarios, the concept of distance between two numbers is used in various fields such as physics, engineering, and economics.
Final Thoughts
In conclusion, the numbers that are at a distance of 6 from the number 5 are 11 and -1. These numbers can be represented using absolute value notation as |x - 5| = 6. The concept of absolute value notation is a powerful tool used to represent the distance between two numbers, and it has various applications in mathematics and real-world scenarios.
