Combination Formula, Combinations without Repetition. 0000000016 00000 n The Absolute Value Introduction page has an introduction to what absolute value represents. For example |3| = 3 and |-5| = 5. Example 1: Solve the absolute value equation. Section 2-14 : Absolute Value Equations. Absolute Value means... how fara number is from zero: "6" is 6 away from zero, and "−6" is also6 away from zero. The absolute number of a number a is written as $$\left | a \right |$$ And represents the distance between a and 0 on a number line. 0000001651 00000 n Sometimes solutions to absolute value equations are asked to be graphed on a number line. The absolute value MUST be by itself on one side of the equation before splitting into two equations. 0000002622 00000 n |x-k|, if xk, then |x-k|=x-k. The absolute value of a number can be thought of as the value of the number without regard to its sign. A very basic example … To solve for first isolate the absolute value portion on one side of the equation and all other constants on the other side. The absolute value bars act like a grouping symbol. Explain how absolute value would be used to express that number in this situation. ∣ x ∣ = − 5. The absolute value is isolated on the left-hand side of the equation, so it's already set up for me to split the equation into two cases. 0000005240 00000 n Example 6. If the absolute value of an expression is set equal to a positive number, expect two solutions for the unknown variable. Set up two equations and solve them separately. 49 34 0000005935 00000 n Thus we can simply replace the absolute value bars with parentheses, and the equation will still hold true for these values of x. 0000055362 00000 n The General Steps to solve an absolute value equation are: Rewrite the absolute value equation as two separate equations, one positive and the other negative; Solve each equation separately; After solving, substitute your answers back into original equation … Example  (1.1)  shows that a general case of  | x |  =  a,    is solved by    x  =  +a. An absolute value equation is an equation that contains an absolute value expression. Thanks to all of you who support me on Patreon. Even though the numbers –5 and 5 are different, they do have something in common. 0000002383 00000 n When solving absolute value equations examples such as this one, look to get the absolute value bars by themselves, all on one side of the equals sign.
