C. In each of the following y varies directly as x . Find the values as Indicated.
1. If y=8 when x = 24, find y when x = 6
2. If y = 18 when x 9, Find y when x = 11​

Step-by-step explanation:

[tex]y = kx[/tex]

1.

[tex]8 = k(24)[/tex]

[tex] \frac{8}{24} = \frac{k24}{24} [/tex]

[tex]k = \frac{1}{ 3}[/tex]

[tex]y = \frac{1}{3} (6)[/tex]

[tex]y = \frac{6}{3} [/tex]

[tex]y = 2[/tex]

2.

[tex]18 = k(9)[/tex]

[tex] \frac{18}{9} = \frac{k9}{9} [/tex]

[tex] k = 2[/tex]

[tex]y = 2(11)[/tex]

[tex]y = 22[/tex]
