If s varies directly as t and inversely as v, then which of the following equations describes the relation among the three variables s, t, and v? * 1 point
A. t/s=kt/v
B. s=kt/v
C. s=k/tv

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
