Write and solve an absolute value equation representing the maximum and minimum serving temperatures for hot cream soup. RF2.8 : I can verify solutions to an absolute value equation and identify extraneous roots. Watch Queue Queue. In exercise 1, the equation is absolute value of 3x minus 7 equals to minus 8. References to complexity and mode refer to the overall difficulty of the problems as they appear in the main program. Absolute Value Equations - Sample Math Practice Problems The math problems below can be generated by MathScore.com, a math practice program for schools and individual families. It means that thing inside the absolute value A equals either positive B or negative B. Before we can embark on solving absolute value equations, let’s take a review of what the word absolute value mean. But it had exactly two absolute-value expressions, and nothing else, so the equation could accommodate the isolation of each of the two absolute values.

Equations with absolute values in practice. Sometimes this will give us extraneous solutions. Pay careful attention to how we arrive at only one solution in this example. 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. Do not make the common mistake of just turning every minus sign inside the absolute value bars into a plus sign. If the number is negative, then the absolute value is its opposite: |-9|=9. This new rule is: This will be better understood with an example. Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9.
