It is -14 degrees outside. The weatherman predicts it will be 30 degrees warmer tomorrow at noon. What will the temperature be at noon tomorrow?

16 degrees and 5 scoops

Step-by-step explanation:

-14+30=16

-10/-2=5

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
