Question

PLEAS HELP QUICK!!!!!! MEDAL for correct answer

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks.

Number of pages 50 100 150 200
Cost 1.55 2.25 2.95 3.65


Which equation gives the cost, y, in terms of the number of pages, x?



A.y = 0.014x + 49.15


B.y = 0.014x + 1.55


C.y = 0.014x + 0.85


D.y = 58.8x + 0.85

Answer 1

Alright, I'm in the mood to use the process of elimination.

Answer 2

Alright let's look at the cost for 50 pages.

We can eliminate the answer B because if we use any number besides 0, we would end up with a number bigger than 1.55.

We can eliminate the answer A because we're adding 49.15 to any response. That means that the number of pages would have to be negative which is possible in my own universe (Let's not talk about that)

We can eliminate the answer D because we're multiplying 50 by 58.8 which is already surpassing 1.55.

This leaves the answer to be C.

Please sue me if I'm wrong :)

Answer 3

ok let me get my lawyer

Answer 4

just kidding let me check

Answer 5

CORRECT thank you will you help me with 4 more

Answer 6

@*Shadow*

Answer 7

Sure :)

Answer 8

Which is an equation in point-slope form for the given point and slope?



Point: ; (8,-4) Slope:-5/6



A.y+4=-5/6(x+8)




B.y-4=-5/6(x+8)




C.y+4=-5/6(x-8)




D.y-4=5/6(x-8)

Answer 9

@*Shadow*

Answer 10

Sorry, was checking something.

Answer 11

What is the point-slope form of the equation of a line that passes through the point (1, 4) and has a slope of -3?


A.y-1=-3(x-4)


B.y+4=3(x+1)


C.y+4=-3(x+1)


D.y-4=-3(x-1)

so what do you think for this 2?

Answer 12

@*Shadow* you still here?

Answer 13

@NunChuckBoy3101 you still want help ?

Answer 14

yes please would you like a medal to?

Answer 15

i don't care about medals. only like to help others :)

Answer 16

ok

Answer 17

So first job is to expand all the options you have. multiply it all out.

Answer 18

because i can open another question so you and @*Shadow* can both have them

Answer 19

Which is an equation in point-slope form for the given point and slope? Point: ; (8,-4) Slope:-5/6

A.y+4=-5/6(x+8)

B.y-4=-5/6(x+8)

C.y+4=-5/6(x-8)

D.y-4=5/6(x-8)

so it would be D

Answer 21

can you wait 10-15 minutes ? i have to go really important. but i will be back

Answer 22

sure

Answer 23

what do you think @*Shadow*

Answer 24

@NunChuckBoy3101 you still here ?

Answer 25

hey i am back now

Answer 26

@abdullah1995

Answer 27

ok

Answer 28

so first thing you want to do is to expand every option you have. expand the brackets

Answer 29

ok i already did those will you help me with this 1

Answer 30

ok post the question

Answer 31

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks:


number of pages 50 100 150 200
cost 1.25 1.85 2.45 3.05


Which equation gives the cost, y, in terms of the number of pages, x?



A.y = 0.012x + 49.985


B.y = 0.012x + 1.25


C.y = 83.3x + 0.65


D.y = 0.012x + 0.65

Answer 32

@abdullah1995

Answer 33

ok lets try to solve this. consider the number of pages your x value and charges as y value to make co-ordinates that is (50, 1.25) ( 100, 1.85) and so on use only two pairs so i choose 50 1.25 and 100 and 1.85 now take the slope

Answer 34

the options that are given are actually in the form y=mx+b ; once you find the slope you will find the m value. looking at the options it is either going to be 0.012 or 83.3

Answer 35

so b

Answer 36

nope

Answer 37

what did you get as your slope value ?

Answer 38

84

Answer 39

hang on i subtracted wrong

Answer 40

its not 84. try again

Answer 41

(y2-y1)/(x2 - x1) = m

Answer 42

(50, 1.25) ( 100, 1.85)

(1.85-1.25)/(100-50) = m . if you solve it you will get 0.012

Answer 43

i know i just did i have no idea ho i got 84 lol

Answer 44

how*

Answer 45

ok i got 0.012

Answer 46

if you are still confused ask the question. solving for marks is not enough. otherwise we can move ahead

Answer 47

no we can move ahead

Answer 48

ok great ! now we have m value. we also have (x, y). there are a lot of pairs you can just take one of them.

y = mx+b ( input x, y and m and solve for b )

Answer 49

?

Answer 50

(1.85) = (100)(0.012) + b

(1.85)-(100*0.012) = b

b = 0.65

Answer 51

oh wait its y = 0.012x + 0.65

Answer 52

did you get it ? more importantly did you understand the whole process ?

Answer 53

yes let me submit

Answer 54

alright sweet.

Answer 55

yes it was correct thank you if i have any more questions like this i will tag you in it

Answer 56

sure thing. if i dont see the tag send me a private message and we can work through it

Answer 57

thank you im about to tag you in something

Answer 58

sure thing
