4. Is the graph an example of direct variation? If so, what is the constant of variation?

C) yes, 2

Step-by-step explanation:

A direct variation means that the graph is a straight line. In this case it is:

Yes, the graph is an example of direct variation.

To find the constant of variation, you can use the formula:

y =

Now, substitute the x- and y-variables for a given point:

1 =

Finally, solve for k:

1 =

k = 2

The constant of variation is 2.

yes because they have the same amount of green and blur marbles.

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
