Question

if x and y are in inverse proportion check whether (x+1) and (y+1) are also in inverse proportion​

Answer 1

Answer:

No, (x+1) and (y+2) are not in inverse proportion.

Step-by-step explanation:

If x and y are in inverse proportion, then its product is k.

Taking example,

let x=4 and y=5

then, xy=20

x+1=5 and y+1=6

(x+1)(y+1) = 30

Hence from the above example, it is proved.

Answer 2

Answer:

No

(x+1) and (y+1) are not in inverse proportion.

Step-by-step explanation:

How?

Let 'x' be 7 and 'y' be 8

The inverse proportion of x and y is 7×8=56

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

x+1 = 7+1 = 8

y+1 = 8+1 = 9

Inverse proportion of (x+1) and (y+1) is 8×9=72

Hence, proved.
