Drag each equation show if it could be a correct first step to solving the equation. 4(3+x)=36.

Step-by-step explanation:

4(3+x)=36

4*3+4*x=36

12+4x=36

4x=36-12

4x=24

x=6

b. astronomers

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
