Question

y is inversely proportional to x³
When x is 2, y value is 0.5
Find y in terms of .x.​

Answer 1

Answer:

If y is inversely proportional to X, this means that

X1 : X2 = y2 : y1

Note that the order of X1 : X2 is reversed in y2 : y1. That’s the reason it is called inversely proportional. If X were proportional to y, we would have X1 : X2 = y1 : y2.

Filling in the known values gives

4 : 8 = y2 : 3 eq.

y2 = 3/2.
