If x is inversely proportional to y and x = 9 when y = 4, find the law containing x and y
- x = \(\frac{16}{y}\)
-
x = \(\frac{36}{y}\)
- x = \(\frac{y}{36}\)
- x = \(\frac{13}{y}\)
The correct answer is: B
Explanation
x = \(\frac{K}{y}\)
9 = \(\frac{K}{4}\)
K = 9 x 4 = 36
Therefore, the law connecting x and y is: x = \(\frac{36}{y}\)
