lyssa 3 years ago This is the ineuality that I need to solve |2X+1|-3 > 6 My work: 2X+1>9 2X+1<-9 -1 -1 -1 -1 _____________________ 2X>8 2X<-10 My answers: x>4 X<-5 But what doesnt make sense is that X is greater than four but at the same time less than -5 I dont think I did this right!

1. lyssa

I am just confused... did I get it right or did I solve the inequality wrong

2. lyssa

ok

what u think now ?

4. lyssa

I got it wrong I AM STILL confused grrrr

5. lyssa

how does this make any sense that X is greater than 4 but less than -5

6. ganeshie8

good confusion @lyssa :)

7. ganeshie8

think of it as : X is greater than 4 \(\textbf{some times and, }\)X is less than -5 \(\textbf{some other times !}\)

8. ganeshie8

you want one practical example ?

9. ganeshie8

where that thing is useful ?

10. lyssa

Oh. I was thinking to hard

11. ganeshie8

12. ganeshie8

19. ganeshie8

if i move forward 4 feet, il land in safe area. if i move backward 5 feet also, its safe

20. ganeshie8

i need to move either four feet forward (or) 5 feet backward

21. ganeshie8

anything less than 4 and greater than -5 is dangerous

22. ganeshie8

i can express the situation as : move >4 distance or move <-5 distance

23. ganeshie8

x > 4 or x < -5

24. ganeshie8

hope i didnt confuse u too much :\

25. lyssa

Well I got it when you said the first thing sorry:D Thanks sooooo much

26. ganeshie8

np... glad to hear u got it :)
