HELP!!! The town of Swanford has a population of 12,500, but it is decreasing at a rate of 4% each year.
Which equation models the population of Swanford, where p is the population after t years?

A. p=12,500(1.04)^t
B. p=12,500(1.4)^t
C. p=12,500(0.096)^t
D. p=12,500(0.96)^t

Add, subtract, multiply, or divide as indicated. list any restrictions for the variable(s) and simplify the answers when possible. 1) x-2 / x+5 + 3x / 2x-1 2) x+6 / x-6 - x^2 / x+6 3) x+9 / x-4 + x+2 / x^2-11x+28 4) x / x^2-64 + 11 / 2x^2+11x-40 5) 5 / x + 11 / x-3 - x-4 / x^2+2x-15
