Answer 8

n0 @freckles

Answer 9

you are charged 10 dollars for membership + 1.5 per each movie

so if you wanted to buy one movie wouldn't it be 10+1.5
and if you wanted to buy two movies wouldn't it have been 10+1.5(2)

Answer 10

so if you wanted to buy x movies then it would be 10+1.5x

Answer 11

ok

Answer 12

Answer 23

yes the integers is this set {...,-3,-2,-1,0,1,2,3,...}

Answer 24

the integers include negative numbers

Answer 25

may you jone question is the answer a

Answer 26

so that set will not work for the domain

Answer 27

ok

Answer 28

but if you have integers that are positive that will work

Answer 29

very

let total cost = y , number of movies = x

y = 1.5x + 10

Answer 30

and also 0 of course

Answer 31

ok

Answer 32

once of your choices give you all positive integers union 0.

Answer 33

so the answer is a

Answer 34

no

Answer 35

a is the set of all integers

Answer 36

we already said this will not work

Answer 37

because you cannot include negative numbers

Answer 38

so b

Answer 39

now you are just guessing

Answer 40

which choice says you buy either 0 or a positive amount of movies?

Answer 41

c then because 0 and higher will be positive right??

Answer 42

yep

Answer 43

the domain is the set of integers 0 or more

Answer 44

may you guys help me with another

Answer 45

You attend an amusement park with your family. Your parents buy you an all-ride pass for $20, shown as f(x). Instead of getting a pass, your parents decide to pay $4 for each ride they take, shown as g(x). What function shows the correct combination of these two functions to represent the total cost to them of attending the amusement park that day, shown as h(x)?

f(x) = 20x, g(x) = 4, h(x) = 20x + 4
f(x) = 20, g(x) = 4, h(x) = 4 + 20
f(x) = 20, g(x) = 4x, h(x) = 4x + 20
f(x) = 20x, g(x) = 4x, h(x) = 20x + 4x

Answer 46

let total cost = y , number of movies = x

y = 1.5x + 10 and yea

Answer 47

@freckles

Answer 48

ok all-ride pass means you only have to pay one time for any x rides you go on

Answer 49

so which function makes since for f(x)?

Answer 50

sense*

Answer 51

b?

Answer 52

c

Answer 53

well f(x)=20 yes
for any amount of x rides you go on you only have to pay 20 dollars

which function makes since for g(x)?
you are given that they have to pay 4 dollars for each ride
so if they go on 1 ride it is 4 dollars
if they go on 2 rides it is 8 dollars
if they go on 3 rides it is 12 dollars
so if they go on x rides then it is ?

Answer 54

16

Answer 55

was i right please just tell ME

Answer 56

1 ride ->4
2 ride ->2(4)
3 ride ->3(4)
x ride->x(4) or 4x
do you understand how i got this

Answer 57

yes am i right though you have not told me yet

Answer 58

is 4x the same as 4?

Answer 59

no

Answer 60

if so then you are right
if not then you are not

Answer 61

so f(x)=20 and g(x)=4x
so h(x)=f(x)+g(x)

Answer 62

so i am right

Answer 63

b is not correct
@bohotness was correct

Answer 64

A cell phone plan has a monthly cost that is shown in the table below. What is the correct statement regarding the average rate of change during the 40-minute time of talk?


Total minutes of talk time
Monthly cost of cell phone
0
$19.95
10
$20.45
20
$20.95
30
$21.45
40
$21.95
The average rate of change is $0.50, meaning that for each minute of talk time, the monthly bill increases by $0.50.
The average rate of change is $0.50, meaning that for every ten minutes of talk time, the bill increases by $0.50.
The average rate of change is $0.05, meaning that for each minute of talk time, the monthly bill increases by $0.05.
The average rate of change is $0.05, meaning that for every ten minutes of talk time, the bill increases by $0.05.
