On time only of this test i need to pass

answer:

4x + 1 = 13

well the answer is x equals 3 or x=3

step-by-step explanation:

4x + 1 = 13

subtract 1 from both sides, which would be:

4x + 1 - 1 = 13 - 1

then, simplify your answer, which would be:

4x = 12

next, divide both sides by 4, which would be:

finally, simplify you answer, which means you should get:

x = 3

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
