Figuring direct and inverse variation

WebDirect variation. The phrase “ y varies directly as x ” or “ y is directly proportional to x ” means that as x gets bigger, so does y, and as x gets smaller, so does y. That concept can be translated in two ways. for some constant k. The k is called the constant of proportionality. This translation is used when the constant is the ... WebExample.

Example: If y varies directly as x and given y = 9 when x = 5, find: a) the equation connecting x and y. b) the value of y when x = 15. c) the value of x when y = 6. Solution: a) y ∝ x i.e. y = kx where k is a constant. Substitute x = 5 and y = 9 into the equation:

WebJoint variation represents a combination of direct and inverse variation, so, obviously, at least three variables must be involved. We express them as x , y and z . Quantities that are in inverse variation (for example x and y ) are multiplied with each other and written as a product, while the variables that are in direct variation are written ...

WebIn notation, inverse variation is written as. Example: Suppose that y varies inversely as x and that y = 8 when x = 3. a) Form an equation connecting x and y. b) Calculate the value of y when x = 10. Solution: i.e. xy = k where k is a non-zero constant. a) Substitute x = 3 and y = 8 into the equation to obtain k. 3 × 8 = k ⇒ k = 24.
