Can Someone 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

Answer 1

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.

Answer 2

@ganeshie8 You Think you could help?

Answer 3

Part A:

(4,410) and (8,770)
770-410 = 360 = 90
8-4 = 4

y = 90x+50
-90x
-90x + y = 50
(-1)-90x + (-1)y = (-1)50

90x - y = -50 <-- standard form of Ax + By = C

Answer 4

Get it?

Answer 5

how would i ? Write the equation obtained in Part A using function notation.

Answer 6

f(x) is the same thing as y, so simply exchange y with f(x). First put it in the form of y = mx + b

So, f(x) = 90x + 50

Answer 7

i get it when people explainn it , but when im on my own, its like im in a space ship

Answer 8

cx

Answer 9

Can you help me with the last part?

Answer 10

Sure!

Answer 11

Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals

Answer 12

Hm, well, I would graph the days on the x axis, 0 through 10 with intervals of 1. And graph the cost on the y axis, from 0 through 950 at intervals of 90.
