Question

Suppose that x and y vary inversely, and x = 3 when y = 10. Write the function that models the inverse variation.

Answer 1

Answer 2

y = k(1/x)
10 = k(1/3)

Answer 3

k = 3*10 = 30

Answer 4

y = 30/x

Answer 5

Can you help me with some more @bahrom7893
thanks

Answer 6

Sorry, probably not, just follow along what I did.

Answer 7

Its fine, but can you just try this one
Suppose that y varies directly with x and inversely with z, and y = 50 when x = 15 and z = 3. Write the equation that models the relationship. Then find y when x = 8 and z = 4.
