16. Find y when x= 3, if y varies directly as x and y = 9 when x = 1.

[tex]\\[/tex]

y varies directly as x

  • y = kx

-------------------------------

[tex]\color{green}\underline\mathbb{SOLUTION:}[/tex]

[tex]\\[/tex]

  • y = 9, x = 1
  • 9 = k · 1
  • 9/1 = k
  • 9 = k

---------------------

  • y = 9x
  • y = 9 · 3
  • y = 27

  • The value of y is 27.
