we know that
If is a factor of the function
then
is a root of the function f(x)
therefore
For the value of the function must be zero
Verify
Substitute the value of in the function
therefore
<u>the answer is</u>
Yes, is a factor of the function f(x)
Answer:
The mass of each passenger is 550 kg.
The mass of front decoration is 200 Kg.
Step-by-step explanation:
Given : A roller coaster train with 6 passenger cars and the front decoration has a mass of 3500 kg. when the train has the front decoration and only 4 passenger cars, it has a mass of 2400 kg.
To find : What is the mass of the decoration and of each passenger car?
Solution :
Let the mass of each passenger is x.
Let the mass of front decoration is y.
Mass of 6 passengers and front decoration = 3500 kg.
The equation form is ..........[1]
Mass of 4 passengers and front decoration = 2400 kg.
The equation form is ........[2]
Solving equation [1] and [2]
Subtract equation [2] from [1],
Put value in [1],
Therefore, The mass of each passenger is 550 kg.
The mass of front decoration is 200 Kg.
