Thanks for helping!

Answer 3

Ok!

Answer 4

so \(|x| = ????\)

Answer 5

I got 72

Answer 6

so if \(|x| = 72\), what can x be?

Answer 7

So the answer is 72? D?

Answer 8

what is |-72| ???

Answer 9

-6?

Answer 10

| | means absolute value. so |3| = 3 and |-3| = 3

what is |-72| ???

Answer 11

Ok so, |x| over -6 = -12. First we need to find X, So multiply each side of the equation by -6, SO! If X is you believe you got 72, test it first by diving it by -6, that equals 12! A negative and a positive make what???? A negative! So it's true that positive 72 divided by negative (-6), equals negative (-12)! So you are correct, it is D. Hope this helps, Have a nice day, Let me know if you need help on anymore questions! @JokerSmart

Answer 12

it is not D

Answer 13

Thank you both on helping me!

Answer 14

So, its not positive?

Answer 15

try this again

| | means absolute value.

so |3| = 3 and |-3| = 3

what is |-72| ???

Answer 16

@JokerSmart It would be D, or C, but on other looks, I'd say C due to -72 being included in the options. Sorry if I don't make much sense! :)

Answer 17

I'll just go with C, since it has both, no problem!

Answer 18

I went over my work, I totally think its C now :) Thanks guys!!!

Answer 19

" It would be D, or C,...." :p

you shouldn't come on here answering stuff that you don't understand. pure and simple.

Answer 20

WELL, both answers are correct- in a way. Haha.

Answer 21

they're not both correct! that 's the point :p

if you say \(|x| = 72 \implies x = 72\) you would be wrong because \(|x| = 72 \implies x = \pm 72\)
