Question

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.

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

Answer 1

In function notation simply means as f(x) =
so you use the slope-intercept form from the previous question.

Answer 2

remember f(x) =
is y =

Answer 3

f(x)=2?

Answer 4

if y = mx + b
2x + 3y = 1200
in slope intercept form is?

Answer 5

y=-2/3x+400

Answer 6

yes,
f(x) = -2/3x + 400

Answer 7

Ok so how do I explain how I know that?

Answer 8

hmm, it says to explain the graph.

Answer 9

Graph of function represents it's slope?

Answer 10

The graph would represent the profit of the company. As it says so in the paragraph, if the equation represents the profit the graph would just illustrate that.

Answer 11

Thank you!

Answer 12

so how would u do the function notation @shamil98

Answer 13

@rileymathewr03 The form is f(x)=mx+b. mx is -2/3x and b is 400. so the answer is f(x)=-2/3x+400
