Question 744055: Y varies jointly as x an the inverse of z. When y=8 and x=4, z=7. Find the constant of variation and determine the value for y when x=9 and z=21. Answer by solver91311(24713) (Show Source):
Can't do this. You start out telling us about a relationship between Y, x, and z. Then you give values for y, x, and z. Y and y are two different things.
