\[options a. b \ge 8 ,b \ge -6 , c. b \le 8 ,d. b \le -6\]

2. blahblah_who_cares

What is the question?

3. ashlynn143

oh yah ok \[-b-7 \le -1\]

4. wetlife

solve algebraically. u got this thing!

5. ashlynn143

i need help that is why i asked

6. blahblah_who_cares

Well think of the question with the less than or equal to symbol as an equal sign. Just remember if you divide by a negative the symbol will become a greator than or equal to.

7. wetlife

One treats an inequality just like and equation algebraically except that the inequality is reversed when multiplied or divided by a negative number.

8. blahblah_who_cares

So what answer did you get ashlynn?

9. ashlynn143

not yet hold on let me think then i will ask

10. ashlynn143

so is it \[b \le -6\]

11. ashlynn143

or d

12. blahblah_who_cares

Well I think you forgot 1 step that both I and wetlife have said about multiplying or dividing by negatives.

13. DLS

b>-6 i suppose

14. ashlynn143

i didn't need to here i will show you how i got it

15. DLS

\[-b-7 \le -1\] \[-b \le 6 \] b>=-6

16. blahblah_who_cares

DLS the problem with your work is that your less than or equal to sign cannot end up as a greator than sign. It is impossible for that to happen.

17. ashlynn143

\[-b - 7\le -1 \] \[-b - 7 = -1\] \[-b = 6\] \[-b \le 6\]

18. blahblah_who_cares

yes ashylnn, but you are missing the last step. You must simplify equation. .You are not looking for what negative b is, but you are looking for just the variable b

19. ashlynn143

yes so i would divide it like this ?? |dw:1357805403002:dw|

20. blahblah_who_cares

ummm.. no. Because you want b on one side, you would not divide both sides by b. Hint: -5= -1*5.

21. ashlynn143

what where would you get a negative 5 and that is a 6 in my drawing

22. wetlife

b/b=1 if b not 0 and 6/b=6/b.

23. wetlife

now you have -1<=6/b

24. blahblah_who_cares

ashylnn my point is to help. It is not to give answers. The example of -5 = 5*-1 is an example to help give you a hint. It has nothing to do with your problem. It is to give you an idea of where you need to fix

25. ashlynn143

ok i thought that it involved my question

26. blahblah_who_cares

Well I learned something in the process, so thank you.

27. ashlynn143

what is that

28. ashlynn143

what is the * thing in the hint / example

29. blahblah_who_cares

it means times

30. ashlynn143

ok

31. ashlynn143

but isn't it that what you do on one side you do to the other to

32. blahblah_who_cares

Yes. That is correct. So what do you understand so far?

33. ashlynn143

ok so i think i know how to solve the problem correctly this time

34. ashlynn143

|dw:1357806023062:dw|

35. ashlynn143

right

36. blahblah_who_cares

Correct. I am assuming that you either multiplied both sides by -1 or divided both sides by -1

37. ashlynn143

i multiplied both sides but i got it correct??

38. blahblah_who_cares

multiplying by both sides is the correct way. I am also saying that if you had divided it by -1 you would have gotten the same answer. Both ways are correct

39. ashlynn143

ok thank you

40. blahblah_who_cares

Also I have noticed you are using the asteric symbol. Just remember that asteric symbol is only used on the computer. When done on paper, the correct way is to use a dot in the middle|dw:1357806252885:dw|

41. ashlynn143

yes i know that as well because is you were to do x on a problem like this it would get someone confused

42. blahblah_who_cares

Yep.

43. ashlynn143

ok thanks you very much maybe now i can kinda do the other ones good and if there is really hard one can i ask you for help?

44. ashlynn143

@blahblah_who_cares ^^^^

45. blahblah_who_cares

Well Im probably going to crash for the night pretty soon. Its 12:30 am for me.

46. ashlynn143

ok thanks

47. ashlynn143

good night
