So both of these x values satisfy the equation.

There are two reasons for this. Create an absolute value equation to represent the situation. So that's our solution set. Even with the absolute value, we can set each factor to 0, so we get —4 and 1 as critical values.

The y-intercept is negative 3, so 1, 2, 3. Let me write it a little bit neater. So if you divide both sides by negative 5, you get a negative 14 over negative 5, and you have an x on the right-hand side, if you divide that by negative 5, and this swaps from a less than sign to a greater than sign.

Graphing Equations This tutorial covers: Provide additional opportunities for the student to write and solve absolute value equations. We see the solution is: Maybe this is 0, this is 1, this is 2, 3, maybe that is negative 1. Examples of Student Work at this Level The student: Either x minus 5 is equal to positive So we have our two constraints.

Well, how would I do that? The x-intercept would be at x is equal to She starts her video when the bird is feet horizontally from her, and continues filming until the bird is at least 50 feet past her.

The Rectangular Coordinate System This tutorial covers: Click on Submit the arrow to the right of the problem to solve this problem. Equality and order relations[ edit ] Two complex numbers are equal if and only if both their real and imaginary parts are equal.

You might say maybe this could be the positive version or the negative, but remember, absolute value is always non-negative. Instructional Implications Model using absolute value to represent differences between two numbers.

So we have two sets of constraints on the set of x's that satisfy these equations. For example, represent the difference between x and 12 as x — 12 or 12 — x.This absolute value equation is set equal to minus 8, a negative number.

By definition, the absolute value of an expression can never be negative. Hence, this equation has no solution.

Solved: Write and absolute value equation that has the given solutions of x=3 and x=9 - Slader/5(1). Ask the student to solve the second equation and interpret the solutions in the context of the problem. Ask the student to identify and write as many equivalent forms of the equation as possible.

Then have the student solve each equation to show that they are equivalent. Consider implementing MFAS task Writing Absolute Value Inequalities (A-CED). Let's do some compound inequality problems, and these are just inequality problems that have more than one set of constraints.

You're going to see what I'm talking about in a second. So the first problem I have is negative 5 is less than or equal to x minus 4, which is also less than or equal to More Formal. More formally we have: Which says the absolute value of x equals: x when x is greater than zero; 0 when x equals 0 −x when x is less than zero (this "flips" the number back to positive); So when a number is positive or zero we leave it alone, when it is negative we change it to positive using −x.
