Question
If y is inversely proportional to x + 1, and y = 2 when x = 1,what is the value of x when y = 4?x =
Solution
If y is inversely proportional to x + 1, we can express this relationship as y = k/(x + 1), where k is the constant of proportionality.
We know that y = 2 when x = 1, so we can substitute these values into the equation to find k:
2 = k/(1 + 1) 2 = k/2 k = 4
Now that we know k, we can find the value of x when y = 4:
4 = 4/(x + 1) 1 = 1/(x + 1) x + 1 = 1 x = 0
So, the value of x when y = 4 is 0.
