Answer:
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
Answer:
30 out of 50 times.
Step-by-step explanation:
1 attempt represents 3 out of 5 times.
10 attempts equals 1 attempt x 10.

3 x 10 = 30
5 x 10 = 50.
Therefore, your solution is 30 / 50 times.

Answer:
<u>t = t₀ - 3n</u>
Step-by-step explanation:
Let t be the temperature and t₀ be the initial temperature of the day
Let n be the number of hours after the initial temperature ( t₀) was registered
Let -3 be the constant of change of temperature ( In 4 hours it went down 12 degrees)
Now, let's write down the expression that shows the temperature change each hour, this way:
t = t₀ - 3n
After 2 hours
t = t₀ - 3 * 2 = t₀ - 6
After 5 hours
t = t₀ - 3 * 5 = t₀ - 15
After 3 hours and 30 minutes
t = t₀ - 3 * 3.5 = t₀ - 10.5
