If y is a positive proportional function of Z, Z is an inverse proportional function of X, and X ≠ 0, then what is the functional relationship between Y and X? They say y = k1z, z = K2 / X y=k1k2/x Why is Z = 2K / x?

If y is a positive proportional function of Z, Z is an inverse proportional function of X, and X ≠ 0, then what is the functional relationship between Y and X? They say y = k1z, z = K2 / X y=k1k2/x Why is Z = 2K / x?

∵ y is a positive proportional function of Z and Z is an inverse proportional function of X
∴Y=K1Z,Z=K2/X
The positive ratio is: y ∶ z = K (k is a constant)
The inverse ratio is Z · x = K (k is constant)
In order to distinguish: y ∶ z = K1 (K1 is constant) Z × x = K2 (K2 is constant)
After deformation: y = k1z, z = K2 / X
The functional relationship between Y and X is an inverse proportional function. The formula is y = K1 × K2 / X
