The answer is c

Step-by-step explanation:

5x+3y=19

multiply x 2: 10x+6y=38

2x-4y=-8

multiply by -5: -10x+20y=40

now you can add the two equations:

10x+6y=38

-10x+20y=40

add equations 0x+26y=78

Answer:

$P(t)=25,000(1.12)^t$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$P(t)=a(b)^t$

where

P(t) is the population in Madison

t is the number of years

a is the initial value

b is the factor of growth

we have

$a=25,000\ people\\b=1.12$

substitute

$P(t)=25,000(1.12)^t$

3400 dollars is placed in an account with an annual interest rate of 8.25%. How much will be in the account after 25 years, to t

Mice21 [21]

$A = S(1+r)^{t}$ is the formula for an annual interest rate.

A = the future amount
S = initial amount
r = rate of interest
t = time in years

Now plug in all variables into the equation.

$A = 3400(1+.0825)^{25} = 24670.419$

To the nearest cent would be rounding the answer to the nearest hundredth.

$24670.419 = $24670.42$

The answer is $24670.42
