Inverse variation 2008-05-22 From leria:In Boyle's law, the pressure of gas varies inversely with the volume of the gas. A volume of 11.2 liters of air exerts a pressure of 2.0 atmospheres. determine the constant of variation and write an equation the models the relationship between the pressure of the gas P and its volume, V. Use the equation to predict the volume of air necessary to exert a presure of 0.25 atmospheres.Answered by Janice Cotcher.     Direct and inverse Variation 2007-04-03 From liz:how do you tell if an equation varies Directly or Inversely? ex. x= 2y or xy+12=3 i know that if you have three numbers (x. y, z) that it varies jointly but how do you tell if it is Inverse or Direct? Thanks for the Help! -lizAnswered by Stephen La Rocque.     Direct and inverse variation 2007-03-03 From Rene:Hi I'm Rene, I'm stuck with some problems in direct and inverse variation. I know how to solve direct and inverse problems when only one variation is in a question at a time. EX: p varies inversely as the square root of q, and when p=12, q=36 find p when q=16 12*6 =p*4 72=4p 18=p But how would you solve a problem like..... If s varies directly as r and inversely as t, and s=10 when r=5 and t=3, for what value of t will s=3 when r=4 ?Answered by Penny Nom.     Direct and Inverse variation 2006-10-27 From Vishalinee:i'm not sure how to use the words direct variation and inverse variation to describe thre relationship between: a. speed and distance b.speed and time c. distance and time. and then i need to create equations using the descriptions. i am really messed up with direct and inverse variation.Answered by Karen McIver.     Direct and inverse variation 2004-10-05 From Abraham:Given that y varies inversely as x and x varies directly as z.If z is doubled then y is halved.Why is that true.Please explain.I'm having trouble understanding the different types of variationAnswered by Penny Nom.     d varies inversely with g 2004-09-07 From Ashlyn:d varies inversely with g when d=-8 and g=2 a. write d as a function of g using function notation. b. find d(10). Answered by Penny Nom.     Direct and inverse variation 2000-12-12 From Ashley:I'm stuck on this unit of direct and inverse variation..please and my problems and show me how to do each PLEASE!!! Assume that y varies directly as x If y= -4 when x = 2, find y when x= -6 Assume that y varies inversely as x If y =-4 when x=2, find y when x =-6Answered by Penny Nom.
