Question

Hey guys I need help with some questions from my Algebra 1 class
1.Solve for x: −5|x + 1| = 10
2.Solve for x: |x − 2| + 10 = 12
3.The minimum and maximum temperature on a cold day in Lollypop Town can be modeled by the equation below:

2|x − 6| + 14 = 38

What are the minimum and maximum temperatures for this day?
4.Compare and Contrast: Two equations are listed below. Solve each equation and compare the solutions. Choose the statement that is true about both solutions.




|5x − 6| = −41

|7x + 13| = 27

Answer 1

Okay.
Let's get started..
First you want the absolute value equation by itself and then solve for it..
-5|x+1| = 10
divide both sides by -5
|x+1| = -2
and now you have two equations.
x + 1 = -2
and
-(x+1)=-2 or simply x+1 = 2

Answer 2

Mkay I follow

Answer 3

just solve it from there.
x+1 = -2 , x + 1 = 2
you get x = -3 , and x = 1.
Try doing the second one.

Answer 4

Okay I got x=4 and x=0

Answer 5

|x − 2| = 2
x = 4 , x = 0, yep correct.

Answer 6

Woohoo :D

Answer 7

Can u help meh with the next one?

Answer 8

2|x − 6| + 14 = 38
get |x-6| by itself first.

Answer 9

Okay

Answer 10

Hold on I think I got an answer
