The car has an initial speed of 30 units and is slowing down by 35 units per second ⇒ answer C
Step-by-step explanation:
The form of the linear function is f(x) = m x + b, where
- m is the rat of change
- b is the initial value
The changing speed of a car is modeled by the function s(t) = -35t + 30, where t is time in seconds.
We need to interpret the model
∵ The changing speed of a car is modeled by s(t) = -35t + 30
- Compare between the model and the form of the linear function
∴ m = -35 and b = 30
∴ The initial speed is 30 units
∴ The speed is changing by -35 units per second
- If the value of change of the speed is negative, means the
car is slowing down by this rate
∴ The car is slowing down by 35 units per second
The car has an initial speed of 30 units and is slowing down by 35 units per second
