Jo Steig The absolute value symbol is really shorthand for what we call a piecewise described function. The algebraic definition of abolute value is as follows:
When you take the absolute value of a number, the result is always positive, even if the number itself is negative. For a random number x, both the following equations are true: This means that any equation that has an absolute value in it has two possible solutions.
If you already know the solution, you can tell immediately whether the number inside the absolute value brackets is positive or negative, and you can drop the absolute value brackets. Plug in known values to determine which solution is correct, then rewrite the equation without absolute value brackets.
To solve this, you have to set up two equalities and solve each separately. Set Up Two Equations Set up two separate and unrelated equations for x in terms of y, being careful not to treat them as two equations in two variables: Sciencing Video Vault 1.
This is solution for equation 1. This is the solution for equation 2. If you plot the above two equations on a graph, they will both be straight lines that intersect the origin. Writing an Equation with a Known Solution If you have values for x and y for the above example, you can determine which of the two possible relationships between x and y is true, and this tells you whether the expression in the absolute value brackets is positive or negative.
Plug these values into both equations. Equation 2 is the correct one. You can now drop the absolute value brackets from the original equation and write instead:Directions for all Anticipation Guides: Before reading, in the first column, write “A” or “D,” indicating your agreement or disagreement with each statement.
Solving Absolute Value Equations and Inequalities 51 An absolute value inequality such as |x º 2|. For example, because of the equation above, if a term's total amount of information stays the same, then the more that the term 'intends' or signifies about objects, the fewer are the objects to which the term 'extends' or applies. The equation used above is called Tolerance and is used whenever you can “tolerate” something for a given interval. The absolute value inequality below represents how long (in minutes) Mr. Brust can watch one of Mr.
As you read, compare your opinions with . Dec 22, · SO2 could theoretically “deplete” ozone by absorbing the UV-A radiation necessary for photolysis of O2, the first step in ozone formation, but that step occurs much higher in the stratosphere than the altitude at which sulfate aerosols form.
