Solve 7x- c= k for x. OA.
k+c
7
OB. X = 7(k - C)
OC. X = 7(k+C)
OD
A4-c
х

The final answer for this equation is x = (k+c)/7

Step-by-step explanation:

7x - c = k

Add c on both sides of the equation.

7x = k + c

Divide 7 on both sides of the equation.

Answer is what the person said above me.

Step-by-step explanation:

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

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
