F x varies inversely as y and y varies directly as Z, what is the relationship between x and z?
x \(\alpha\) z
x \(\alpha \frac{1}{z}\)
x \(\alpha z^2\)
x \(\alpha \frac{1}{z^2}\0
説明
x \(\alpha \frac{1}{y}\)
y \(\alpha z\)
the relationship = x \(\alph \frac{1}{z}\)
y \(\alpha z\)
the relationship = x \(\alph \frac{1}{z}\)
