X = -2 + y
-16x - 3y = -25

Let's substitute x into the second equation, since the first equation already tells us what x is.

Multiply -16 by x, which is (-2 + y)

-16(-2 + y) -3y = -25

Simplify.

32 -16y -3y = -25

Simplify. Get the variable on one side.

-19y = -57

Divide both sides by -19 to solve for the variable.

y = 3

Now plug y = 3 into one of the equations to find x. I'll use the first equation, since it's easier.

x = -2 + y
x = -2 + 3
x = 1

The answer is x= 1, y =3, which may be written as (1, 3). Hope this helps.

Assoli18 [71]

Answer:

$a_0 = 14000$

$a_{n} = 0.9a_{n - 1},~~ for ~n \ge 1$

Step-by-step explanation:

Let "a" represent the population.

$a_0$ is the initial population.

$a_n$ is the population at year n.

Since the population decreases 10% each year, that means that each year, the population is 90% of the previous year.

The initial population is 14,000.

Each year fater than, the population is 90% of the population of the previous year, or 0.9 time the population of the previous year.

$a_0 = 14000$

$a_{n} = 0.9a_{n - 1}, ~~for ~n \ge 1$
