Answer: [tex]x=2[/tex]
Step-by-step explanation:
Inverse proportion equation has this form:
[tex]y=\frac{k}{x}[/tex]
Where "k" is the constant of variation.
We know that "y" is inversely proportional to "x" and when [tex]x=3[/tex], [tex]y=6[/tex]
Then, we can substittute these values into the equation and solve for "k" to find its value:
[tex]6=\frac{k}{3}\\\\6*3=k\\\\k=18[/tex]
Finally, we need to substitute "k" and [tex]y=9[/tex] into the equation and solve for "x":
[tex]9=\frac{18}{x}\\\\x=\frac{18}{9}\\\\x=2[/tex]
Answer:
x=2
Step-by-step explanation:
y is inversely proportional to x is written as:
x ∝ 1/y
When the proportion is removed, a constant is introduced. We have to find the constant first to find the value of x in y = 9
So,
Removing the proportionality symbol will give us:
x=k/y
As we know that x=3 for y=6 so
3 = k/6
3*6=k
So,
k=8
Hence the value of proportionality constant is 8.
Now putting the value of y which is 9
x=k/y
=>x=18/9
=>x=2
