Question

last part of the math Qs i have been asking all day.

Answer 1

previous info:

Answer 2

original something:

Answer 3

Need help for both 5 and 6?

Answer 4

yea

Answer 5

shadow helped me with 1 - 4 but i think ive bothered shadow enough lmao

Answer 6

The 5th question is like the first

They give you the data, you just have to make the equation

Answer 7

y= -2/3x + 513

Answer 8

i think .-.

Answer 9

Well lets look at the information is gave us first

Do you know what the x and y represent here?

Answer 10

wait hold up that would be the equation but thats not what they are asking here they are telling me to 'In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.'

Answer 11

x = sandwich y =wraps

Answer 12

I know, I am just trying to get the equation for both to have something to visually compare

Right, what is the cost for each (sandwich and wrap)?

Answer 13

3 for wraps and 2 for sandwiches

Answer 14

Good and what is the total?

Answer 15

for buying one of each? or the total at the end of the month?
one of each = 5
end of month = 1593

Answer 16

For this month (for question 5 only, they gave us a total)

Answer 17

yea, at the end of the month, in part 5, it says that the total is 1,593

Answer 18

Yes

Since the money earned goes by selling things = total earned

Then,

\(3x+2y=1593\)

Answer 19

First month: \(2x+3y=1470\)

Second month: \(3x+2y=1593\)


They are both written as cost of sandwich\(+\) Cost of wrap = Total earned


Looking at these equations, what can you tell?

Answer 20

that the store got more popular in the 2nd month so there was more things sold 0.0

Answer 21

So they are similar in that the prices were the same but different in that the second month they earned more money :P

Answer 22

XD nah. i can tell that the price at the end of the month,the prices of both the wraps and sandwiches are the same, but Sal earned more money at the end of the 2nd month the 1st month

Answer 23

Good

Answer 24

so thats what i put then?

Answer 25

Looks good to me

Answer 26

ok. only 1 prob with it. it has to be in 3 sentences .-.

Answer 27

Trick for that, change the commas you added into periods. (:

Answer 28

okie

Answer 29

that still only makes 2 sentences .-.

Answer 30

i have about 7 mins left before i gtg

Answer 33

ok ty.

Answer 34

If you want me to explain why, I would be happy to

Answer 35

ok all thats left is 6 now

Answer 36

if u could explain it later thatd be great but i wanna wrap this up before i leave

Answer 37

\(y=mx+b\)

m is the rate
b is the starting point

Answer 38

Where does the graph for 6 start?

Answer 39

at 300, then it goes down to 450. .-.

Answer 40

that doesnt sound right XD

Answer 41

300 does not go down to 450 lol

Answer 42

yea thts what i thought lmao but 450 also cant go up to 300

Answer 43

i spent at least 2 hours last night trying to figure this stupid thing out

Answer 44

it starts from 300 and goes down to ~260

Answer 45

That is beyond the point, we want to find the slope form 2 points

Answer 46

Let's use (0,300) and (150,200)
(x\(_1\),y\(_1\)) (x\(_2\),y\(_2\))

To find the slope use

\(\large \frac{y_2-y_1}{x_2-x_1}\)

Answer 47

200 - 300

Answer 48

Good

Answer 49

Now solve it

Answer 50

200 - 300 = -100
150 - 0 = 150

Answer 51

100
____
150

Answer 52

\(-\frac{100}{150}\)

You can divide both by 50 to simplify

Answer 53

-2/3

Answer 54

Good

Your equation is

\(\large y=-\frac{2}{3}+300\)

Answer 55

thats the answer for 6 correct?

Answer 56

Yes

Answer 57

ok ty i gtg :)

Answer 58

Np, take care

Answer 59

have a nice night :)

Answer 60

Same to you
