Answer 9

Yes. So what is |-8| equal to?

Answer 10

If you can't answer the question what is the value of |-8|, you can't answer your question, that's why I'm asking it.

Answer 11

|-1| = 1
|-2| = 2
|-3| = 3
|-4| = 4

so |-8| = what?

Answer 12

The question is the same. theri no other explanation.

Answer 13

Only know that is not the (A) =64

Answer 14

Ok horse. Last chance. Do you want to drink?

What is the value of |-8| ?

Answer 15

James the question does not have more information.

Answer 16

|-1| = 1
|-2| = 2
|-3| = 3
|-4| = 4
|-5| = 5
|-6| = 6
|-7| = 7
|-8| = 8

Hence x = -8 is one value that satisfies the equation |x| = 8.
Therefore either B or C is the answer.

Now the question is, does x = 8 also work. I.e., is it the case that
|8| = 8?

Answer 17

I think it is 8.

Answer 18

What is the definition of this | | sign?

What does |x| mean?

Answer 19

i know. I'm making sure you do.

Answer 20

Not sure,but how can i do...

Answer 21

|x| = x, if x > 0
|x| = 0, if x = 0
|x| = -x, if x < 0

Hence |1| = 1, because 1 > 0
|2| = 2, because 2 > 0
but |-1| = -(-1) = 1, because -1 < 0
|-2| = 2, because -2 < 0

Answer 22

Similarly |-3| = 3 and |3| = 3

Answer 23

So what is the value of |-4| ?
