Question

please help



Part A: Nadia rented a stage platform at $410 for 4 days. If she rents the same stage platform for 8 days, she has to pay a total rent of $770.

Write an equation in the standard form to represent the total rent (y) that Nadia has to pay for renting the stage platform for x days. (4 points)

Part B: Write the equation obtained in Part A using function notation.(2 points)

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)

Answer 2

Let me see what I can do..

Answer 3

ok thanks :)

Answer 4

Well we have the points (4, 410) and (8, 770).

Answer 5

So we can find out slope, which is 90.

Answer 6

I mean -90x + y= 50.

Answer 7

So -90x - y = 50 would be for A?

Answer 8

Yes.

Answer 9

Now we have to write -90x - y = 50 in the form of y = mx + b.

Answer 10

So that would be y = -90x + 50?

Answer 11

Yes.

Answer 12

To graph that you will plot the two points (4, 410) and (8, 770) and draw a line threw them. It will have a slope of -90 and a y-intercept of 50.

Answer 13

That's for Part C ^^

Answer 14

to put it as function notation would you change the y to a f(x)? like f(x) = -90x + 50?

Answer 15

Yes.

Answer 16

ok thank you! your helping me out a lot today
