Marla has a pet hamster. the hamster makes 3 laps around her cage every minute. what line represents the situation? line a line b line c line d

Let

x-------> the time in minutes

y------> the number of laps

we know that

In this problem the linear equation represent a direct variation and the slope is equal to

so

the equation of the line is

For

the value of y is equal to

Plot the point in the graph

therefore

the answer is

The solution is the line b

see the attached figure to better understand the problem

x=half

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
