Answer:
x=6
AC = 28
Step-by-step explanation:
4x+4= AC
4x +4 = 14 + 3x -4
4x-3x= 14-4-4
x = 6
AC = 4(6) +4 = 24+4 = 28

Answer:
y = 5 e^r * t
Let y be the population in billions and t the value of elapsed years
7 = 5 e^r * t is the equation being used where t = 15
7/5 = e^r * t
ln 7/5 = r * t taking ln of both sides
r = .336 / 15 = .0224
y = 5 e^(.0224 t) is then our equation
Check - suppose you want y at 2020
y = 5 e^(.0224 * 20) would be the equation
y = 5 e^.449 = 7.83 billion - seems to be a reasonable answer
