Ayoung sumo wrestler decided to go on a special diet to gain weight rapidly. w(t), left parenthesis, t, right parenthesis models the wrestler's weight (in kilograms) as a function of time t (in months). w(t) =80+ 5.4t what was the wrestler's weight before his special diet?

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? )
