A zoo is creating a new fenced living area for its tortoises. The zookeeper estimates that they will need a space that is about 40 feet by 50 feet to accommodate the animals. Which type of formula should the zoo use to determine how much fencing they will need to construct the pen? a.) Volume b.) Perimeter c.) Profit d.) Area

I'd use perimeter. Will determine how much feet of materials will be needed.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

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