You can express this indirect (inverse) variation as:
y+=+k%2Fx where k is called the constant of variation.
To find the value of k, substitute the given y = 10 and x = 25.
10+=+k%2F25 Multiply both sides by 25.
k+=+250 So now you have...
y+=+250%2Fx and if you substitute x = 35, you can find the corresponding value of y.
y+=+%28250%2F35%29 Evaluate.
highlight%28y+=+7.143%29
