Azookeeper is monitoring the population of gazelles. the herd needs three times more males than females to thrive, and the zoo only has room for 12 female gazelles. let x = the number of female gazelles and y = the number of male gazelles. write the constraints to represent a thriving population of gazelles at the zoo.
a. x > 0 and y > 0
b.0 < x ≤ 12 and 0 < y ≤ 36
c.0 < x ≤ 12 and y > 36
d. x > 0 and y < 23
