2. anonymous

what does the inequality look like when it is solved?

3. UnkleRhaukus

$|x|>1$ $\rightarrow x>1, x<-1$

4. anonymous

r u sure?

5. anonymous

can you explain to me how you got to that answer

6. UnkleRhaukus

yeah.

7. UnkleRhaukus

well absolute value signs means magnitude

8. UnkleRhaukus

ie, there are positive and negative solutions

9. anonymous

ok, i get that, but why is x greater than 1 but less than -1?

10. UnkleRhaukus

|x|>1 the positive solution→x>1, the negative solution→-x>1 which becomes x<-1

11. anonymous

why does the > change?

12. UnkleRhaukus

the inequity symbol changes when dividing by a negative
