Step-by-step explanation:
A function is a relationship between inputs where each input is related to exactly one output.
The function for the value of the motorcycle after x years.
y = 8000 - 500x
y = -500x + 8000
Option C is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
A new motorcycle has a value of $8,000.
Every year its value decreases by $500.
Now,
y = amount of the motorcycle
x = number of years
The function for the value of the motorcycle after x years.
y = 8000 - 500x
y = -500x + 8000
Thus,
The function for the value of the motorcycle after x years.
y = 8000 - 500x
y = -500x + 8000
Option C is the correct answer.

what happens to the pressure of a container if the volume is doubled and the temperature is kept the same?
- impossible to determine with the info provided
- the pressure will increase
- the pressure will decrease
- the pressure will stay the same
Answer:
- the pressure will decrease
(volume is doubled ,the pressure reduced by half).
Step-by-step explanation:
P_1 V_1=P_2 V_2
This equation shows that, as volume increases, the pressure of the gas decreases in proportion.
Similarly, as volume decreases, the pressure of the gas increases.

If you wash your car every 15 days & I wash mine every 20 days, in how many days will we be washing them on the same day?
Answer: 60 days
Step-by-step explanation:
To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:
Multiple of 15 = 15, 30, 45, 60, 75, 90
Multiples of 20 = 20, 40, 60, 80, 100
Lowest common multiple = 60
Therefore, they'll be Washing the car on thesame day on the 60th day.
