If z varies directly as x and imversely as y, and z = 9, when x = 6 and y = 2, find z when x = 8 and y = 2
Z = kx/y 9 = k(6)/(2)
9 = k(3)
9/3 = k(3)/3
3 = k
Question po sir pwede po ba ganitong solution or mali po ?

Mali po yung problem no.2 niyo po, ang totoong sagot po is 3, why?
R=4/9(27)
9
=27/9
=3
So that's the answer, mali po talaga
