Working simultaneously at their respective constant rates, machines a and b produce 800 nails in x hours. working alone at its constant rate, machine a produces 800 nails in y hours. in terms of x and y, how many hours does it take machine b, working alone at its constant rate, to produce 800 nails?
y = −4/3 x
given the radical form:
use the exponent rules:
we can write as:
therefore, in exponential form is
