Unit 6 Day 1: Absolute Value Equations / Algebra TT

Front

Define absolute value.

Back

A number's distance from zero.

Front

What is the FIRST step to solving the equation |x + 1| = 4?

Back

Set up 2 equations: x + 1 = 4 and x + 1 = -4.

Front

When do you set up 2 equations in |x + 2| + 3 = 4?

Back

After you subtract 3 from both sides.

Front

What is the FIRST step to solve the equation -2|x + 3| = -10?

Back

Divide by -2 on both sides.

Front

What does |x| represent?

Back

The distance of x from 0 on the number line.

Front

How do you solve |x| = a where a > 0?

Back

Set up two equations: x = a and x = -a.

Front

What is the solution to |x - 5| = 3?

Back

x = 8 or x = 2.

Front

What is the absolute value of -7?

Back

7.

Front

If |x + 4| = 0, what is x?

Back

x = -4.

Front

What is the first step to solve |2x + 1| = 5?

Back

Set up two equations: 2x + 1 = 5 and 2x + 1 = -5.
