The variables x and y vary directly. use the given values to write an equation that relates x and y. x = 18 y = 6

Step-by-step explanation:

It is given that x and y vary directly. It means y is directly proportional to x.

It can be written as

          .... (1)

where, k is the constant of proportionality.

The given values are x=18 and y=6.

Substitute these values in the above equation.

Divide both sides by 18.

Substitute the value of k in equation (1).

Therefore, the required equation is .

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
