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

3. LaynaMae

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

4. sierraabel

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

5. ~Chance~

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

6. kantalope

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

7. sierraabel

8. LaynaMae

@~Chance~ , Yes I am

9. LaynaMae

It's a school @sierraabel

10. skullpatrol

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

11. LaynaMae

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. PeterPan

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

14. LaynaMae

@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. LaynaMae

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

16. PeterPan

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. PeterPan

Hey skullpatrol, look above your post ^.^

19. LaynaMae

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. LaynaMae

By someone HELPING me ?!

22. skullpatrol

23. LaynaMae

@ganeshie8

24. LaynaMae

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. PeterPan

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

28. PeterPan

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

29. ganeshie8

ok peter wil walk u through i hope :)

30. LaynaMae

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. PeterPan

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. LaynaMae

Alright :)

34. LaynaMae

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

35. PeterPan

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

36. LaynaMae

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

37. LaynaMae

Right

38. PeterPan

So how do you represent that in your function?

39. LaynaMae

Ummm would that be that is equals 10 ?

40. PeterPan

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. LaynaMae

I suppose :o

42. PeterPan

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. LaynaMae

10 ?

44. PeterPan

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

45. LaynaMae

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

46. skullpatrol

Try using "t" to represent time.

47. PeterPan

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. LaynaMae

Good God I'm so confused ...

49. PeterPan

:3 10 and 5 make?

50. LaynaMae

15 ._.

51. PeterPan

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

52. LaynaMae

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. LaynaMae

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. PeterPan

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

56. LaynaMae

Including the 15 , right ?

57. PeterPan

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

58. LaynaMae

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

59. PeterPan

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

60. LaynaMae

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

61. PeterPan

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. LaynaMae

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

63. LaynaMae

@ganeshie8

64. skullpatrol

|dw:1378737848010:dw|

65. PeterPan

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. PeterPan

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. PeterPan

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. PeterPan

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. LaynaMae

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. PeterPan

Okay ^.^ Good luck.

75. skullpatrol

Thanks for trying.
