Use the graph to write an explicit function to represent the data and determine how much money amy earned in week 5.
graph with x axis labeled number of weeks and ranges from zero to seven, y axis labeled money earned, in dollars, and ranges from zero to one hundred eighty with points at one comma five, two comma fifteen, three comma forty five and four comma one hundred thirty five
f(n) = 5(3)n + 1; f(5) = 3,645
f(n) = 5(3)n; f(5) = 1,215
f(n) = 5(3)n − 1; f(5) = 405
f(n) = (3)n − 1; f(5) = 81

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

3       6.8

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

step-by-step explanation:

answer: i could not see part the question so ill explain how to get the answer

step-by-step explanation: for instance the distance she travele d is 10 and she traveled the same amout each mile so do 10 divided by how many miles she drove each time and you ge your answer.
