Question

I require assistance once again.​

Answer 1

Explanation:

1. Equation changed to slope-intercept as thus

y = 490 - 0.667x

with slope = -0.667

intercept on y axis = 490

intercept on x axis = 735

2. Description about graphing the line using slope-intercept method

On the y (vertical axis): maximum value of y = 490 and that is when x = 0

On the x (horizontalal axis): maximum value of x = 735 and that is when y = 0

Incrementing on x axis cause a decline of y-axis (as shown in the graph as attached)

3. Equation of the function notation

F(x) = 490 - 0.667x

where wrap, y= F(x) and sandwich, x

4. See attached graph but try and continue the projection to intercept x at 735

5. Equation for next month is 2x + 3y = 1593

For the graph;

Slope remains the same as previous month = -0.667

intercept on y axis = 531

intercept on x axis = 796.5

The graphs look a little similar just that the intercepts are different.

Answer 2

I can help you with 1, 2 and 3.

Explanation:

1. 2x + 3y = 1470

Subtract 2x from both sides: 3y= -2x+1470

Divide three from both sides: y= \frac{-2}{3}x +490

2. 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.
