Question

|-2x - 4| _< 12
1. Solve the inequality. Show ALL work
2. If x represents positive amounts in kilograms, what is the solution set?
3. only positive integer solutions to the equation can be used and accepted. How does this change the answer to question number 2? Explain

Answer 1

_< = less than or equal to

Answer 2

|-2x - 4| ≤ 12
-2x - 4 ≤ 12
-2x ≤ 16
x ≥ -8

-2x - 4 ≥ -12
-2x ≥ -8
x ≤ 4

-8 ≤ x ≤ 4

Answer 3

is that for question 1?

Answer 4

Yes.

Answer 5

And question 2.

Answer 6

okay thanks . do u know how to solve 3?

Answer 7

Well, it's actually 1 ≤ x ≤ 4 for #2.

Answer 8

#3
You have to cut out the - answers by changing the lowest amount. and making 1 the lowest number.

Answer 9

thanks sooo very much :)

Answer 10

You're welcome.
