Question

(GIVE A MEDAL AND FAN) PLEASE HELP!!!
Part A: Maria rented a coat at $285 for 3 days. If she rents the same coat for 6 days, she has to pay a total rent of $510.

Write an equation in the standard form to represent the total rent (y) that Maria has to pay for renting the coat 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 1

@nerlineg @DaBest21 help please

Answer 2

help please guys!!!!! @DaBest21 @nerlineg @mathmath333 @Pinkflower guys!!!

Answer 3

i really need help on this please!!!!!

Answer 4

@EmilyF03 do u know what standard form is

Answer 5

no :/

Answer 6

are you there? @DaBest21

Answer 7

ok standard form is A*x+B*y=C

Answer 8

okayy so whats nexts?

Answer 9

is this flvs

Answer 10

yes :(

Answer 11

what lesson

Answer 12

03.11

Answer 13

k one sec

Answer 14

ok

Answer 15

B)f(x)=75x+60
C) To graph you would start at (0,60) and go up with a slope of 75 use intervals of 1 on the x axis and intervals of 75 on the y axis.

Answer 16

ill do a real quick one sec

Answer 17

OKAY

Answer 18

Let (3,285) and (6,510) reprsent the coordinate points, where x = number of days coat is rented for; and y = price of rental

Given these 2 points, we could write the equation of the straight line.

We need the slope.

Slope = (510-285)/(6-3) = 225/3 = 75

So the slope is 75.

So the equation of the line is y - 285 = 75(x - 3)
y - 285 = 75x - 225
y = 75x + 60

Answer 19

THAT its for part B? right? @mathway

Answer 20

the above isnt standard form

Answer 21

@mathway it says standard form no variables can be on the right

Answer 22

−75x+y=60 is a correct standard form equation

Answer 23

and @mathway plz do not copy and paste answers from previous questions about this

Answer 24

its in the code of conduct

Answer 25

@DaBest21 so the correct answer for part B its: −75x+y=60

Answer 26

yes

Answer 27

@DaBest21 It is best to guide them first before giving the answers! and for your quetsion, I lost the connection, so I wasn't able to type it next to my last comment. :/

Answer 28

Remember that the standard form is ax+by=c

Answer 29

i know

Answer 30

and for part C the correct answer its: To graph you would start at (0,60) and go up with a slope of 75 use intervals of 1 on the x axis and intervals of 75 on the y axis. ???

Answer 31

1y=y

Answer 33

yes

Answer 34

oops forgot the to put the link. again due to the lost of connection. Are we clear now, NOT @DaBest21 ?

Answer 35

whoa calm down ok

Answer 36

potassium.

Answer 37

and for part A? @DaBest21

Answer 38

-75x+y=60 but if u want to be thechnical do -75x+1y=60 which changes nothing

Answer 39

i was directing the end of that not at u @EmilyF03

Answer 40

Part A: -75x + 1y = 60,
Part B: f(x)=75x+60
Part C: To graph you would start at (0,60) and go up with a slope of 75 use intervals of 1 on the x axis and intervals of 75 on the y axis. <SO THATS the complete answers?

Answer 41

??/

Answer 42

yes

Answer 43

thank you!!!! @DaBest21 and @mathway
