Question

Please help, I'll fan & give a medal.

Answer 1

What I have so far... Did I do them right?
Part A: No, this table doesn't represent a function because -1 and -2 repeat.

Part B:
f(h) = 3h + 1
f(3) = 3(3) + 1
f(3) = 9 + 1
f(3) = 10

What do I do for C?

Answer 2

And also for B, f(h) means the hours that she practiced?

Answer 3

hey, what is the Question all about ?

Answer 4

Sorry, what do you mean? I posted it above @Koikkara

Answer 5

what you mean is I have to draw a table representing all these hints?

Answer 6

Does the question mean multiple or just 1 ordered pair? I can't put a table in the assignment I'm doing.

Answer 7

@ganeshie8 this user may understand it better than me.

Answer 8

@ganeshie8 @wolf1728 @Compassionate @Miracrown @Whitemonsterbunny17 Can any of you guys help me with this?

Answer 9

your answer for part B, f(3) = 10, is correct.

what does f(3)=10 represent here ?

Answer 10

means the hours that she practiced?

Answer 11

the hours that she practiced what ?

Answer 12

could you explain using more sentences ?

Answer 13

your teacher likes you more when you use more sentences in your explanation

Answer 14

The meaning of f(3) explains how many hours Diana practiced every day.

I'm not sure of what else I can say /:

Answer 15

that is wrong, f(3) is "not" the hours that Diane practiced everyday

Answer 16

f(3) is the "number of matches" that Diane has won when she practiced 3 hours everyday

Answer 17

isn't 3 the hours tho? the question only asks to explain f(3)

Answer 18

f(3) = 10


3 = number of practice hours
10 = number of matches won

Answer 19

Oops, sorry I read it wrong.

Answer 20

thats okay...
so what is your answer for "interpret the meaning of f(3)" ?

Answer 21

The meaning of f(3) is how many matches Diana won when she practiced for 3 hours every day.

Answer 22

Excellent!

Answer 23

now read part C

Answer 24

Ok done

Answer 25

Part C may throw you off as it has no numbers

Answer 26

Yea that's why I'm so confused haha

Answer 27

it says Diane practices for "b" hours

what does that even mean ?

Answer 28

she practiced for 3 hours

Answer 29

part C says, " Diane practices tennis for b hours "

Answer 30

it is "b" hours
not 3, we're done with numbers

Answer 31

how can anyone practice for "b" hours

Answer 32

Oh ok. Not sure if it has anything to do with this, but doesn't b represent the y-intercept? Is that appilied here or no?

Answer 33

the letter "b" means different things in different contexts

thats the problem we need to learn to deal with in algebra

Answer 34

In our present problem, if it helps, you may think of "b hours" to mean "some hours"

We don't know how many hours she has practiced yet, we assume it is "b" hours

Answer 35

Oh. This section and assignment covers that so I didn't know if it would be used or not

Answer 36

ok that makes sense

Answer 37

If we assume she practices for "b hours",
how many matches do we expect her to win according to the formula in part B ?

Answer 38

Um 4? How would I find that i'm not sure

Answer 39

may i know how you got 4 ?

Answer 40

whats the formula from part B ?
can you write it here for me please

Answer 41

3h + 1 but i figured it was wrong i just dont know how i'd get that answer

Answer 42

f(h) = 3h + 1

Answer 43

\(3\color{red}{h}+1\) is the number of matches that Diane wins if she practices for \(\color{red}{h}\) hours

Answer 44

\(\text{______}\) is the number of matches that Diane wins if she practices for \(\color{red}{b}\) hours

Answer 45

fill in the blank

Answer 46

10

Answer 47

how did u get 10 ?

Answer 48

f(h) = 3h + 1
f(3) = 3(3) + 1
f(3) = 9 + 1
f(3) = 10

Answer 49

good, now replace \(h\) by \(b\)

Answer 50

because part C is about practing for \(b\) hours
not \(3\) hours

Answer 51

f(h) = 3h + 1
f(b) = ?

Answer 52

f(10) = 3(10) + 1
f(10) = 30 + 1
f(10) = 31

@ganeshie8 Is this right?

Answer 53

why are you plugging in 10 ?

Answer 54

you need to plugin h = b right ?

Answer 55

f(h) = 3h + 1
f(b) = 3b + 1

thats it.

Answer 56

so, if she practices for "b" hours, she will win "3b+1" matches

Answer 57

so the ordered pair is (b, 3b+1)

Answer 58

see if that makes sense

Answer 59

Am I plugging in numbers anywhere? Because if so, I'm lost. /:

Answer 60

no, we're done.... this is algebra and we're playing with alphabets as variables

bye bye to numbers

Answer 61

Ok so for Part C I'm just going to write (b, 3b + 1)?

Answer 62

Yep!

Answer 63

that means :
if she practices "b" hours, then she will win "3b+1" matches

Answer 64

whatever that means

Answer 65

Haha :P ok thanks!! Do you mind if I open another question and ask another?

Answer 66

I'll try... tag me :)
