The total cost f(x), in dollars, for renting a vacation house for x days is shown:
f(x) = 10 + 250x what does f(10) represent?
a. the number of dollars it costs for 10 people to rent the house
b. the number of houses that can be rented for 10 day
c. the number of days the house can be rented for a cost of $250
d. the number of dollars it costs to rent the house for 10 days

Option D.The number of dollars it costs to rent the house for 10 days

Step-by-step explanation:

we have

f(x) > the total cost for renting a vacation house

x > the number of days rented

we know that

f(x)=10+250x

so

For x=10 days

substitute in the function

f(10)=10+250(10)=$2,510

f(10) represent the number of dollars it costs to rent the house for 10 days

D

Step-by-step explanation:

I got it right on the test

answer: 2 and 1

step-by-step explanation: got this question

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
