Direct Variation (video lessons, examples and solutions)?

WebExample: 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 The equation is xy = 24 b) When x = 10, 10 × y = 24 ⇒ y = WebSolution: Step 1: The problem may be recognized as relating to direct variation due to the presence of the verbiage "is directly proportional to"; Step 2: Using: y = Money Raised at Fundraiser. x = Number of Fundraiser Attendees. k = Constant of Proporationality. y = kx. boxy svg transparent background WebCombined Variation, which involves a combination of direct or joint variation, and indirect variation. For example, the average number of phone calls per day between two cities has found to be jointly proportional to the populations of the cities, and inversely proportional to the square of the distance between the two cities. WebPurplemath.
