the weight of a baby elephant is about 120 kg at birth. Every year his weight increases by 360 kg. whats an algebraic expressionto represent his weieght in years.

Respuesta :

y = 360x + 120.

The y-intercept would be at (0, 120), as at year 0 or x=0, the weight is 120 kg.

If it increases every year by 360 kg, it would be noted in how many years it has been by 360x.
