Question

I need help with a graph can someone please help me????

Answer 1

what type of graph?

Answer 2

it is for x and y

Answer 3

ok do you have an equation?

Answer 4

I have my answers

Answer 5

we need to know what it is you would like help with

Answer 6

ok draw them or type them out

Answer 7

Revenue = $2,220
x = $35 (model A4 phones)
y = $50 (Smartphone Z20)
So, the profit from all phones sold equals $2,220. Therefore, 2220 = 35x + 50y and we see that the total number of phones sold is 51; therefore, x + y = 51.
The two equations are 1) the cost of the phones, and 2) the number of each type of phone sold.
$2220 = $35x + $50y and x + y = 51
$35x + $50y = $2220 To solve:
$35x + $50y = 51($35) multiply the term in second equation by $35
$15y = $2220 – $1785 divide both sides by 15.
$15y/$15 = $435/$15
y = 29 Smartphone Z20 sold

Answer 8

Now, for the second equation replace y with 29 and calculate:
x + y = 51
x + 29 = 51 Subtract 29 from both sides
x + 29 – 29 = 51 – 29
x = 22 model A4 sold
To check the answers, use y = 29 and x = 22 and calculate the original first equation.
$35x + $50y = $2220
$35(22) + $50(29) = $2220
$770 + $1450 = $2220
$2220 = $2220

Answer 9

ok so what is the question?

Answer 10

you have just stated a system of equations

Answer 11

how would I graph it?

Answer 12

would I use 35x and 50x ?
