Question

Z is partly constant and partly varies directly as x and inversely as y^2, z=10 when x=8 y=4 and z=2 when x=6 y=3. find the formula connecting z k and y.

Answer 1

Find z when x=1 y=4

Answer 2

@khally92

Answer 3

Z is partly constant

ok, \(z= \alpha\)

and partly varies directly as x

so.... \(z= \alpha + \beta x\)

" and inversely as y^2"

aha!...can you add that last bit in and then solve....

Answer 4

solve what?

Answer 5

Is the statement complete @HulaHoop. what about y^2. its not in your equation
