1. x and y vary
inversely, and x =
50 when y = 5.
Find k. Then use k
to find y when x =
10.

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
