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
[tex]\\[/tex]
[tex]\color{yellow}\underline\mathbb{ANSWER:}[/tex]
- The value of y is 27.
