Question

Assume that the variables x and y are inversely related. If k = 18, what is the value of y for each of the following points?

Answer 1

Answer:

The values of Y are: 18, 9, 6, 3, 2, 1

Explanation:

It is given that X and Y are inversely related. This can be depicted mathematically as:

$X \alpha \frac{1}{Y}$

i.e. as X increases the value of Y is expected to decrease.

(or) $X =k* \frac{1}{Y}$

where k = proportionality constant which is given as 18

In terms of Y, the above equation becomes:

$Y =k* \frac{1}{X}$

Based on the above equation the table can be filled as :

X     Y     K

1      18    18

2     9      18

3     6      18

6     3      18

9     2      18

18     1     18
