Question

What is the solution set of |x| > 12?
I think its the last option

x < –12 or x > 12

x < 12

x > –12 and x < 12

x > –12

Answer 1

no..it's not the last option

here's a hint:

if you have \[|x| >1\]
the solution set would be
\[\pm x > 1\]
or in compund inequality,
\[x > 1; \; x< -1\]
does that help?

Answer 2

Not really. I thought it would have to be the absolute value so like -12 0r 12.

Answer 3

Idk what the plus/minus sign is...

Answer 4

yes.
x> 12 or -x > 12

now if i divide that second one by -1 i get

x < -12

so the compund inequality is x>12 or x<-12

got it?

Answer 5

plus minus sign means positive/negative

Answer 6

Ooooh. Okay. Thanks. I understand it a lot better now.
