A 30 pound moonling weighs 180 pounds on earth. How much does 300 pound earthling weigh on the moon

Step-by-step explanation:

First thing to know that moon's gravity is just one-sixth of the earth's. So meaning 1/6 × 300 lbs earlthling = 50 lbs.

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
