A car dealership has a sale on cars. People buy 120 cars at the event, which is 80% of their inventory at the dealership. How many cars were at the dealership before the sales event?

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:

after simplifying it i got: -36.25 as my answer. hope that !

4x and 6y

im not sure though

yes
