Question

I WILL GIVE A MEDAL!! A company produces accessories for smart phones and tablets. The profit on each smart phone case is $2 and the profit on each tablet case is $3. The company made a profit of $1,200 on the cases last month. The equation 2x + 3y = 1,200 represents the company's profit from cases last month, where x is the number of smart phone cases sold and y is the number of tablet cases sold.

Answer 1

1.Change the equation into slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all of your work.
2.Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences.
3.Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
4.Graph the function using one of the following two options below. One 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 that can be found in the Course Information area.
5.Suppose in the next month, the total profit on smart phone cases and tablet cases is $1,500. The profit amounts are the same, $2 for smart phone case and $3 for the tablet case. In a paragraph of at least three sentences, explain how the graphs of the functions for the two months are the same and how they are different. Be sure to use complete sentences.
6.Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Answer 2

1. \[y = \left(\begin{matrix}2 \\ 3\end{matrix}\right)x+400\]

Answer 3

@EEmarr could you help me with the rest of them?

Answer 4

I did this same assignment let me tell you what i had and how i got there...

Answer 5

i had to redo this

Answer 6

ahh me too ok one second...what teacher?

Answer 7

Larken

Answer 8

Oh cool i got Lohr.

Answer 9

cool

Answer 10

You in OCVS?

Answer 11

flvs

Answer 12

1.
2x + 3y = 1200
2x-1200=-3y
1/3*(2x-1200)=1/3*-3y
2/3x-400=-y
-2/3x+400=y

Answer 13

The second one you would need to find the slope intercept which was given above, -2/3...
2.
I would put a dot on (0,400) then I would use the slope to do the rest or go 2 points to the right and 3 to the down. After this it should look like 3,398.

Answer 14

Do not use my exact wording...try re wording it or saying if differently.

Answer 15

ok

Answer 16

3.
F(x) = 2x + 1200

Answer 17

Can you do the graph by yourself?

Answer 18

Sorry i have it on paper so i would have to scan it again and stuff...

Answer 19

5.
2x + 3y = 1500
-3y = 2x – 1500
1/3* -3y = (2x – 1500)*1/3
-2/3x + 500 = y

Answer 20

6.
F(x)=mx + b
F(x) = mx + 300
F(x) = 6/9x + 300
F(x) = 2/3x + 300

Answer 21

That should be it....

Heeey ..
@undeadknight26
For #3 , It says to explain what the graph of the function represents ..
What does the graph of the function represent ?
Lol , sorry but I dont get it .
