Do you remember what a function is it is basically an equation (y=mx+b)

3. anonymous

Yes but I'm confused as to what to do .

4. anonymous

8x+10=y y=8x+10

5. anonymous

Are you in Connections Academy? $$\color{red}{Chance}$$

6. anonymous

total playing time = 10[the hours played last week] + (5[number of hours allowed] * 8 [the number of weeks of restriction]

7. anonymous

8. anonymous

@~Chance~ , Yes I am

9. anonymous

It's a school @sierraabel

10. skullpatrol

Why don't you show everybody here your best effort to solve this question?

11. anonymous

There is none . That's why I posted it here . So someone could help me through it .

12. skullpatrol

You want to put NO effort in?

13. anonymous

Such cruelty :( What if x represents the number of weeks that passed, does that help? ^.^

14. anonymous

@skullpatrol I didn't say that nor did I imply that ?? I said I don't know how to do this . Therefore I need HELP .....

15. anonymous

@PeterPan I know right ? Like excuse me if I don't know how to do it .....

16. anonymous

Oh, I was actually referring to Peter's parents... poor Peter :( But we should focus on the problem ^.^

17. skullpatrol

It's not "cruel" to expect someone to show you what they have tried so far.

18. anonymous

Hey skullpatrol, look above your post ^.^

19. anonymous

How can I try it if I don't even know what I'm doing ?? That's my point .....

20. skullpatrol

How can you learn that?

21. anonymous

By someone HELPING me ?!

@ganeshie8

24. anonymous

Seriously -.- If you want to be no help do not comment on my question . Simple .

25. ganeshie8

Im here :) just a simple, twisted word problem it is

26. skullpatrol

learn how to teach yourself

27. anonymous

And a cruel twisted world. This is grown-up tyranny! But anyway Layna, let's get to work ^.^ f(x) = ...

28. anonymous

Oh... ganeshie8 on the case? okay :/

29. ganeshie8

ok peter wil walk u through i hope :)

30. anonymous

I seriously can't believe this guy right now . Anyway , for the people trying to HELP me , let's focus :)

31. skullpatrol

let her walk on her own

32. anonymous

He will? He's too busy not playing :( :D We want a function that tells you exactly how many hours Peter (that's weird >.>) has played given the number of weeks that has passed, since his parents made sure he only plays five hours for every week, ok? ^.^

33. anonymous

Alright :)

34. anonymous

So we need yo set up an equation or function or something , right ?

35. anonymous

Yep, he's already played ten hours, nothing we, or the number of weeks can do about that, right?

36. anonymous

Oh and @skullpatrol , please leave since you are going to be of no assistance . Thanks

37. anonymous

Right

38. anonymous

So how do you represent that in your function?

39. anonymous

Ummm would that be that is equals 10 ?

40. anonymous

Close, but no dice ^.^ f(x) = 10 If you notice, there's no x in this equation. That means the number of hours he's played would be 10, regardless of how many weeks has passed, and if Peter's the kind of boy I think he is, I don't think that's true, he's gonna make the most of the five hours he's allowed to play, right?

41. anonymous

I suppose :o

42. anonymous

Think about it, at the beginning of what I like to call the 'eight weeks of punishment' he's going to play five hours, so at the end of the FIRST week, how many hours would he have played?

43. anonymous

10 ?

44. anonymous

But he's already played for ten hours from last week! `

45. anonymous

Hold on . @skullpatrol I believe I asked you to leave

46. skullpatrol

Try using "t" to represent time.

47. anonymous

Would, but the word problem says 'f(x)' It's just a crummy letter anyway ^.^ Now, Layna, 10 hours from last week, and 5 hours for the first week of the 8 of punishment. That adds up to...what?

48. anonymous

Good God I'm so confused ...

49. anonymous

:3 10 and 5 make?

50. anonymous

15 ._.

51. anonymous

-girls...- haha just kidding! >:) Anyway, that means at the end of the first week, Peter would have played for 15 hours total, right? ^.^

52. anonymous

Yes yes yes ! I was confused about that statement but then I thought about it :p

53. skullpatrol

Have you thought about organizing the facts in a chart?

54. anonymous

Sorry it's too early for algebra . And @skullpatrol I don't need a chart I need complete sentences like the questions asks for .

55. anonymous

What about by the end of week 2? How many hours would Pete have finished by then?

56. anonymous

Including the 15 , right ?

57. anonymous

Well of course... Peter can't un-play the hours he's already played, LOL

58. anonymous

Okay well then he would have played 20 hours ? :o

59. anonymous

That's right :) So what about after x weeks?

60. anonymous

80 ? because that would be the end of the 8 weeks ? :o

61. anonymous

I didn't say 8 weeks. I said x weeks. We don't know what x is exactly, but we do know how many hours Pete would have played at the end of x weeks.... in terms of x, that is ;)

62. anonymous

Sorry but I thought x weeks would be for the whole 8 weeks . -.- and okay

63. anonymous

Week 0 being 'last week' $\Large \left.\begin{matrix} week&0&1&2&3&4&5&6&7&8\\hours \ played &10&5&5&5&5&5&5&5&5\end{matrix}\right.$

66. anonymous

Does this give you an idea?

67. skullpatrol

@LaynaMae read the question carefully and compare it to @PeterPan 's chart :-)

68. skullpatrol

Remember the question is asking for "TOTAL" video time played which would be the SUM of the times in the chart up to that point, right?

69. anonymous

You know what, let's forget about last week, we'll bring it in later. $\Large \left.\begin{matrix} week&\cancel0&1&2&3&4&5&6&7&8\\hours \ played &\cancel{10}&5&5&5&5&5&5&5&5\end{matrix}\right.$

70. skullpatrol

@LaynaMae Are you still there?

71. anonymous

Forgetting that Pete's played ten hours last week, how many hours will he have played, say, at the end of week 4? $\Large \left.\begin{matrix} week&\cancel0&1&2&3&\boxed 4&5&6&7&8\\hours \ played &\cancel{10}&\color{blue}5&\color{blue}5&\color{blue}5&\color{blue}5&5&5&5&5\end{matrix}\right.$

72. skullpatrol

This is what I mean by the student not trying >8(

73. anonymous

Woah excuse me ?? My dog just ran across a busy street and she's only a few years old . Don't tell me what I'm not doing unless you have some facts . Now I'm done here all together I have someone else helping me . Sorry . Question is closed .

74. anonymous

Okay ^.^ Good luck.

75. skullpatrol

Thanks for trying.
