How do you simplify absolute value?
Once you have performed any operations inside the absolute value bars, you can simplify the absolute value.
Whatever number you have as your argument, whether positive or negative, represents a distance from 0, so your answer is that number, and it is positive.
In the example above, the simplified absolute value is 3..
Can an absolute value equation have one solution?
In the case of only one solution, you end up with an absolute value expression equal to zero. Since this means that the distance from zero on the number line is zero, you end up with only one equation.
How do you solve absolute value equations with no solution?
For example, |x|=−1 has no solution. The absolute value of a number is its distance away from zero. That number will always be positive, as you cannot be negative two feet away from something. So any absolute value equation set equal to a negative number is no solution, regardless of what that number is.
How do you solve an absolute value problem?
SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)Step 1: Isolate the absolute value expression.Step2: Set the quantity inside the absolute value notation equal to + and – the quantity on the other side of the equation.Step 3: Solve for the unknown in both equations.Step 4: Check your answer analytically or graphically.
What are the rules of absolute value?
Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number’s sign: if it’s positive, it’s equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.
How do you solve absolute value inequalities?
Here are the steps to follow when solving absolute value inequalities:Isolate the absolute value expression on the left side of the inequality.If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.More items…
What is the absolute value of 3?
For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.
What is the absolute value of 8?
1 Answer. The absolute value of 8 is 8 .
