How do you rewrite an absolute value expression?

if x < 0 then | x | = (-1) x In order to simplify an expression with absolute value, we examine the sign of the quantity inside the absolute value. If that quantity is positive or equal to zero, its absolute value is the quantity itself.

How do you find the absolute value of 2?

The absolute value is just the distance from the origin we can say that 2 is a distance of two units away from 0, but also that −2, the opposite of 2 (and on the other side of 0), is two units away from 0.

What is the absolute value notation?

The most common way to represent the absolute value of a number or expression is to surround it with the absolute value symbol: two vertical straight lines. |6| = 6 means “the absolute value of 6 is 6.” |–6| = 6 means “the absolute value of –6 is 6.” |–2 – x| means “the absolute value of the expression –2 minus x.”

How do you work out absolute value equations?

SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)

1. Step 1: Isolate the absolute value expression.
2. Step2: Set the quantity inside the absolute value notation equal to + and – the quantity on the other side of the equation.
3. Step 3: Solve for the unknown in both equations.
4. Step 4: Check your answer analytically or graphically.

How do you rewrite an expression without the absolute value symbol?

Rewrite the expression without using the absolute value symbol |x-2| if x<2 The rule is that if the expression within the absolute bars is positive, just remove the bars. Conversely, if negative, put a minus sign in front of the expression after removing the bars.

What is the rule for removing the absolute bars in Excel?

The rule is that if the expression within the absolute bars is positive, just remove the bars. Conversely, if negative, put a minus sign in front of the expression after removing the bars.

How do you find the absolute value of an equation?

So we represent absolute value of this equation using the formula: So whenever you see the symbol | |, it means we are taking the absolute value of it where we drop the -ve sign. In other words, you can also say that an absolute value is always +ve.
