While studying a population of porcupines, a group of scientiss caught and tagged 140 porcupines. A week later, the scientists counted 180 porcupines and saw that 14 of them had tags. To the nearest whole number, what is the best estimate for the procupine population

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

thats not a system of equations, that is a solution

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
