Answer:I can help you with 1, 2 and 3. Step-by-step explanation:1. 2x + 3y = 1470Subtract 2x from both sides: 3y= -2x+1470Divide three from both sides: y= \frac{-2}{3}x +4902. To graph it, you would first go to (0,490) because that is where the y-intercept is. Since slope is ride over run, you can either go up 2 left3 or down 2 right 3. You can proceed doing that until you have enough points to draw the line.3. f(x)= -2/3x +490. This function means represents how many wraps are sold based on how many rolls are sandwich.
