what is the value of fraction 1/3x^3 + 5.2y when x = 3 and y = 2?

13.4
16.4
19.4
28.4

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

both have same length

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
