Answer 1

David was looking at his limousine bill and saw that the total number of miles he has ridden in the car was tracked:


Month Miles
5 580
6 695
7 810
8 925



The function representing David's miles per month is f(m) = 115m + 5. What does the 115 represent?
The number of miles at the start
The number of the month when David was riding
The number of miles David had in total
The number of additional miles each month

Answer 2

i was thinking the number of additional miles each month

Answer 3

u were thinking it correctly @shinebrightlikeadimon

Answer 4

okay thanks i have 6 more

Answer 5

f(m) is total miles, m is the month... and 5 is the miles he already walked even before the first month

Answer 6

ohk

Answer 7

Find the average rate of change for the given function from x = −2 to x = 1.

Graph of f of x equals x minus 5

−1
1
−3
3

Answer 8

f(x) = x-5
f(-2) = -2-5 = -7
f(-1) = -1-5 = -6
f(0) = 0 -5 = -5
f(1) = 1-5 = -4

average = (f(1) - f(-2)) / (1-(-2))
avg = (-4 -(-7)) / (1+2) = 3/3 =1

thanks and thanks for showing your work!

Answer 12

After 2 months of living at his new apartment, Henry had 2 cats. Six months later, Henry still had 2 cats. Which of the graphs below models Henry's cat population?

graph of line going through 2, 0 and 2, 8
graph of line going through 2, 2 and 5, 8
graph of line going through 0, 2 and 7, 2
graph of line going through 0, 2 and 4, 10

Answer 13

graph of line going through 0, 2 and 7, 2

Answer 14

cats never increased so, c as y remains constants as x changes

Answer 15

the point c says at the end of 2 months cats were 2, and at the end of 6 months catrs were 2 and even at the end of month 7 cats will be two...
implies that cats never increased more than two nor do they decrease after every month.
and hence the graph and the solution C.

Answer 16

do u understand that @shinebrightlikeadimon

Answer 17

yeah i actually do

Answer 18

great @shinebrightlikeadimon

Answer 19

Below are two different functions, f(x) and g(x). What can be determined about their slopes?

f(x)= 3x − 3 The function g(x) going through 0, 2 and 1, 5

The function f(x) has a larger slope.
The function g(x) has a larger slope.
They both have the same slope.
The relationship between slopes cannot be determined.

Answer 20

as g(x) passes thru (0,2) and (1,5)
slope of g(x) = (y2-y1) / (x2-x1) = (5-2)/(1-0) =3
yes the slope of two of them are equal...
ad the slope is 3 for both of them
and equation of g(x) is given by

y-y1 = slope*(x-x1)
y-2 = 3(x-0)
y = 3x + 2

Answer 21

@shinebrightlikeadimon

Answer 22

would be be c?

Answer 23

yes

Answer 24

thanks okay i got more almost done!

Answer 25

What is the standard form equation of the line shown below?

Graph of a line going through negative 3, negative 1 and 3, 2

y + 1 = one half(x + 3)
y = one halfx + five halves
−x + 2y = 1
x − 2y = −1

Answer 26

wait

Answer 27

k

Answer 28

y-(-1) = slope*(x-(-3))
y+1 = slope*(x+3)

slope = 2-(-1) / (3-(-3)) = 3/6 =1/2

so y+1 = (1/2)*(x+3)

solve ,
2y+2 = x+3
2y-x =1

Answer 29

ans C

Answer 30

@shinebrightlikeadimon

Answer 31

thanks just a little more

Answer 32

Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts?


graph going through negative 1, 1 and negative 1, 5

x g(x)
1 0
3 4
5 8

The function f(x) has a higher y-intercept.
The function g(x) has a higher y-intercept.
They both have the same y-intercept.
The relationship between y-intercepts cannot be determined.

Answer 33

this is the last one :)

Answer 34

ohk

Answer 35

i think D my brother helped me but im not sure

Answer 36

yes it is D

Answer 37

slope of both the functions is undefined

Answer 38

both the functions does not have any y intercepts.
