Introduction
In this article, we will explore the concept of absolute value equations and how to determine the number of solutions for a given equation. We will examine the equation and determine the correct answer from the given options.
Understanding Absolute Value Equations
Absolute value equations are equations that involve the absolute value of an expression. The absolute value of a number is its distance from zero on the number line, without considering direction. For example, the absolute value of 5 is 5, and the absolute value of -5 is also 5.
When solving absolute value equations, we need to consider two cases: one where the expression inside the absolute value is positive, and one where the expression inside the absolute value is negative.
Case 1: Expression Inside Absolute Value is Positive
If the expression inside the absolute value is positive, then the absolute value equation becomes:
To solve for x, we can add 25 to both sides of the equation:
Next, we can divide both sides of the equation by 6:
Case 2: Expression Inside Absolute Value is Negative
If the expression inside the absolute value is negative, then the absolute value equation becomes:
To solve for x, we can distribute the negative sign to the expression inside the absolute value:
Next, we can subtract 25 from both sides of the equation:
Finally, we can divide both sides of the equation by -6:
Analyzing the Results
We have found two possible solutions for the equation : and .
However, we need to consider whether these solutions are valid. Recall that the absolute value of an expression is always non-negative. Therefore, the equation is inconsistent, and there are no valid solutions.
Conclusion
In conclusion, the equation has no valid solutions. The correct answer is:
- D. None
This is because the absolute value of an expression is always non-negative, and the equation is inconsistent.
Frequently Asked Questions
Q: What is an absolute value equation?
A: An absolute value equation is an equation that involves the absolute value of an expression. The absolute value of a number is its distance from zero on the number line, without considering direction.
Q: How do I solve an absolute value equation?
A: To solve an absolute value equation, you need to consider two cases: one where the expression inside the absolute value is positive, and one where the expression inside the absolute value is negative.
Q: What is the difference between a positive and negative expression inside an absolute value?
A: A positive expression inside an absolute value is one that is greater than or equal to zero, while a negative expression inside an absolute value is one that is less than zero.
Q: Can an absolute value equation have more than two solutions?
