Easy Algebra 2 2 2 Direct Variation Youtube This video is about easy algebra 2 2.2 direct variation. about. This algebra video provides a basic introduction into direct variation. it explains how to find y given x when y varies directly with x. it also explains h.
Direct Variation Examples Freemathvideos in this video i will show you how to use direct variation to help determine the missing variable, as well as how to determine i. If you multiply x cm second * y seconds you get xy cm as your answer. and this answer would be equal to the distance (d) in cm that point p has traveled after y seconds. so d cm = x cm second * y seconds. so. d=xy which can be converted to. d x = y or. y=d x which you had as y=blank x. Direct variation and inverse variation are used often in science when modeling activity, such as speed or velocity. some real life examples of direct variation are: the number of hours you work and the amount of your paycheck. the amount of weight on a spring and the distance the spring will stretch. the speed of a car and the distance traveled. For example, if y represents the total cost of buying x items that cost $7 each, then the direct variation equation would be. y = 7x. in this direct variation equation, 7 is the constant of proportionality, which represents the cost per item. and, for example: when x=2, y=14. when x=3, y=21. when x=10, y=70.
