modulus requires to positive and negative solutions

3. anonymous

so my answers are a and b?

4. anonymous

like |x|<1 means x has solutions x<1 and x<-1

5. anonymous

yep neat

6. anonymous

wait

7. anonymous

When we have absolute values, we get two solutions, so we have $-(2x-8)<4 ~~~~\text{and}~~~~(2x-8)<4$

8. anonymous

a and c yeah they did something funny there

9. anonymous

10. anonymous

im confused af

11. anonymous

haha, $-(2x-8)<4$ is also the same as $2x-8>-4$

12. anonymous

when you divide by a negative we usually switch the sign

13. anonymous

perhaps iambatman will give you a clearer explanation

14. anonymous

http://i.imgur.com/RJf4aGR.png so those r my answers?

15. anonymous

|dw:1444559321606:dw| this is essentially what you need to know when you see absolute values

16. anonymous

Yes, your answer looks good! $(2x-8)<4$ and we have $-(2x-8)<4 \implies 2x-8>-4$ remember when we divide by a negative the sign flips.

thank u
