Answer 1

@Vocaloid

Answer 2

Sal’s Sandwich Shop sells wraps and sandwiches as part of its lunch specials.

The profit on every sandwich is $2 and
The profit on every wrap is $3.
Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal’s profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.


Change the equation into slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all of your work below:

Answer 3

2x + 3y = 1,470

solve this for y

Answer 4

2x + 3y = 1,470
-2x -2x
3y/3= (-2x+1470)/3
y=(-⅔)x + 490

Answer 5

what do you mean copy and pasting... why did you just first assume that. im working on this assignment in a doc.. i copy and pasted it here to make sure i was correct.

Answer 6

looks fine then.

Answer 7

now find the slope and y-intercept.

Answer 8

is this it?

Slope-intercept form: y=mx+b, where “m” is the slope of the line and “b” is the y-value at which the line intercepts the y-axis of the graph, the y-value when x=0.
m=(-⅔)
b= 490

Answer 9

good, that's it

Answer 10

awesome :) thx

Answer 11

@Vocaloid ok now following the same like problem about sarah its just a different question but i answered it and i wanted you to check if its correct

Answer 12

Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.

I would begin to graph this line by first putting appropriate numerical values on the y-axis and x-axis of my graph. For example, I know that when x is zero the y-value is huge. The y-intercept is close to 500. So, I would label my y-axis in 10 increments of 100 up to 1000. Next, I appropriately label the x-axis from 0-1000 in 10 increments 100. I would not include either the negative x or y values because it is not possible to sell negative sandwiches or wraps.The line on the graph represents the points at which the profit is $1, 470 for x amount of sandwiches sold and the corresponding y number of wraps that would have to be sold in order to reach that profit point exactly. The first point I would groph would be the y-intercept because I know, from the equation, (0,490) is the point at which the line intercepts the y-axis. The negative slope tells me that the y-values will be decreasing from the y-intercept to y being equal to zero. The -⅔ slope tells me that the y-values will decrease at a rate of 2 while the x-values increase at a rate of 3. I know this because I know slope is equal to the change in rise or fall in the y-direction over run in the x-direction.

Answer 13

Looks fine to me

Very detailed but good

Answer 14

ok great now i do need your help with the rest of the questions

Answer 15

i answered this one as well please check

Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.

Let f(x) be equal to the number of wraps sold to reach a total profit of $1,470 for which the number of sandwiches is equal to x sandwiches. Therefore, the function notation of this equation would be f(x)= (-⅔)x+490. The function f(x) represents the points along the y-axis at which the profit is $1, 470 for x amount of sandwiches sold. The y-axis values are number of wraps that would have to be sold to reach that profit.

Answer 16

@Vocaloid

Answer 17

Good

Answer 18

ok now i need help with this:
Graph the function using one of the following two options below. On the graph, make sure to label the intercepts.
~You may graph your equation by hand on a piece of paper and scan your work.
~You may graph your equation using graphic technology.
Paste your graph below:

Answer 22

Just follow the directions you wrote here and you should be good to go

Answer 23

Try sketching this on paper and take a pic with your phone or something

Answer 24

but how do i like make the graph... i have to use a graphing website?

Answer 25

It says you can draw it by hand and then scan it

Answer 26

ok.... so from what number to what number?

Answer 27

Again, read your directions

Answer 28

i have to do it from 0-1000?

Answer 29

That's what it says

Answer 30

You don't need to calculate every single value, once you have two points you can just connect them in a straight line

Answer 31

I would recommend graphing your x and y intercepts first

Answer 32

(Once you have set up your axes that is)

Answer 33

Need to take a break

After you finish graphing, you can double check by plugging your function into wolframalpha.com

Answer 34

@Vocaloid ok can you atleast tell me what the function is so i can graph it

Answer 35

??? It's the same function you've already been working on

Answer 36

The one about the sandwiches

You know, the one that you wrote that entire huge paragraph explaining how to graph?

Answer 37

Your answers so far have been great, I don't know why you're suddenly struggling with this

Answer 38

Just follow the instructions (you know, the ones that you wrote) and you should be fine

Answer 39

Good demonstration jesus

Answer 40

Cookie what do you have graphed so far?

Answer 41

nothing im confused... what would be my function?

Answer 42

im using this website
http://www.wolframalpha.com/input/?i=graphing

Answer 43

The exact same function we have been working with for this ENTIRE problem

Answer 44

The one about the sandwiches

Answer 45

yes... is this it?
y=(-⅔)x + 490

Answer 46

Yes good

Answer 47

so let me see hold on let me insert that into where it says function

Answer 48

this is what it shows for the graph^^

Answer 49

Take a screen grab and save it

Answer 50

is that what the graph should look like?

Answer 51

Then paste it into your problem

Answer 52

is the graph correct?

Answer 53

Take a screenshot of the graph not the URL

Answer 54

i knoww

Answer 55

Does the slope and y-intercept match the equation?

Answer 56

well i think so the graph goes through the number 40 but then the x-axis ends at 10?

Answer 57

If the slope and y-intercept match the equation, then you should get good to go

Answer 58

*be good to go

Answer 59

right but how do i make sure that the match/

Answer 60

Try adding "from x = 0 to x = 1000" to the end of the function line

Answer 61

im so confused i literally just want to know what the graph will look like

Answer 62

i dont know what to input in the blank parts ....

Answer 63

Type your function into the input section

Then write "from x = 0 to x = 1000"

Then press enter

Answer 64

it doesnt let me put that

Answer 65

ughhhh

Answer 66

Wolframalpha.com

Answer 67

ill just draw it then how would i draw it

Answer 68

Why did I click on this

Answer 69

Im forever notified

Answer 70

Again... if you want to do this by hand you have that entire paragraph of instructions

Answer 71

like please just help me create it...
