Unit 6.E (Part 1) CW: Solving Absolute Value Equations

Solve:

 $|v+8|−5=2$  

• {-1,-15}

• {-1,-5}

• {-15,15}

• No Solution

Solve:

 $−2|−2r−4|=-12$  

• {3,1}

• {-3,-1}

• {-3}

• No Solution

Solve:

 $|2a-10|=6$  

• a = 8, a = 5

• a = 2

• a = 8

• a = 8, a = 2

What is the reason that absolute value is always written as a positive?

• Absolute value is talking about numbers so it must be positive.
• Absolute value does not always have to be positive.
• Absolute value is like a clock it has only positive numbers.
• Absolute value is talking about distance, distance is always measured by positive numbers.

Solve:

 $8|-2x+4|=96$  

• x = -4, x = 8

• x = -4

• x = -4, x = -8

• x = 4, x = 8

Solve the following equation:

 $∣2x+9∣=15$  

• x = 3

• x = 3, x = −6

• x = 3, x = −12

• x = 6, x = −12

Solve.

 $|x+7|=12$  

• x = -5, x = 19

• x = 5, x = -19
