What is the first step in evaluating the expression (5 +8 / 4 x 3)2nd power

Here are the steps for evaluating an expression:

1. Replace each letter in the expression with the assigned value. First, replace each letter in the expression with the value that has been assigned to it.

2. Perform the operations in the expression using the correct order of operations.

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
