Answer:

0.94

Step-by-step explanation:

We know that the given values (9.4,11) and (11,y) are from an inverse variation.

So we can write the function of an inverse variation as:

∝
$\frac{1} {x}$

$y = \frac {k} {x}$

Finding the constant
:

$11 = \frac {k}{9.4}$

k = 9.4*11

k = 10.34

Now finding the missing value
:

$y = \frac {10.34}{11}$

y = 0.94

Therefore, the missing value is (11, 0.94).

Answer: 9.4

Step-by-step explanation:

Here the x-coordinates and y-coordinates have the inverse relation.

⇒
$x\propto(1)/(y)$

⇒
x=(k)/(y)

Where k is variation constant.

Since, point (9.4, 11) is from the inverse variation,

Therefore, this point must be satisfy the above condition,

That is,
9.4=(k)/(11)

k=103.4

Thus, the relation between the coordinates is,

x=(103.4)/(y)

Put x = 11, in the above function,

11=(103.4)/(y)

y=(103.4)/(11)=9.4
