Question

Someone please help explain this to me? I'm desperate!

Answer 1

27. Suppose y varies inversely with x. Write an equation for the inverse variation. Y = 7 when x = 3


28. Suppose y varies inversely with x. Write an equation for the inverse variation. Y = 4 when x = 2.5


29. Suppose y varies inversely with x. Write an equation for the inverse variation. Y = -9 when x = 2


30. Suppose y varies inversely with x. Write an equation for the inverse variation. Y = 5 when x = -5


31. Graph each inverse variation. Xy = 15


32. Graph each inverse variation. Y = -18 / x

34. Identify the excluded value for each function. F(x) = 5 / x


35. Identify the excluded value for each function. Y = 3 / x + 4


36. Identify the asymptotes of the graph of each function. Then graph the function. Y = 1 / x + 2


37. Identify the asymptotes of the graph of each function. Then graph the function. F(x) = -2 / x + 3


38. Identify the asymptotes of the graph of each function. Then graph the function. Y = 5 / x – 4 + 1


39. Identify the asymptotes of the graph of each function. Then graph the function. F(x) = 3 / x – 5 – 1


I know it's a lot, but please! Someone help me with this and explain it to me so I can do it on my own! I really am desperate to know how to do this

Answer 10

the inverse of a number a, is 1/a

an inverse variation is one of the form y= k/x

Answer 11

inverse variation has a constant k of: xy
a direct variation has a constant k of: y/x

so essentially they want you to express this with the given values:

y = (XY)/x for an inverse

y = (Y/X) x for a direct
