To put this into an absolute value equation you would have +0. The +0 is unnecessary so you have . **Remember that the absolute value equation always has the opposite sign of the x-value of the vertex (positive or negative). Then simply set it equal to how far away you are. =4. Example 2: What equation represents all points exactly 2 units from ...

[DOC File]Solving Absolute Value Equations
https://info.5y1.org/absolute-value-of-equation_1_3cdb61.html
Every absolute value inequality is a compound inequality. The 2 separate inequalities come from when you split the inequality once the absolute value is isolated. So first, you isolate the absolute value following all the same steps as you did when isolating the absolute value when solving an absolute value equation.

https://info.5y1.org/absolute-value-of-equation_1_f3c678.html
To solve absolute value equations, remember to do the following: Isolate the absolute value expression on one side of =. So for example, use the Addition Property of Equality to subtract x from both sides of (2x - 3( + x = 2. to result in (2x - 3( = 2 - x. Use the Absolute Value Equation Property to solve two cases without the absolute values ...
