Given the function below, find /(-7)
(x) = -2x-1

For this case we have a function of the formwhere:

We must find the value of the function when. So:

By definition we have to:

Thus, the value of the function is

the correct answer is 5

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
