Elimination method 3x+4y=18 9x-5y=3
tatiyna

Answer:

The solution would be (10, -3)

Step-by-step explanation:

In order to solve using elimination, multiply the top equation by -3 and then add the equations together.

-9x - 12y = -54

9x - 5y = 3

---------------

17y = -51

y = -3

Now that we have a value for y, we can put it into either equation and solve for x.

3x + 4y = 18

3x + 4(-3) = 18

3x - 12 = 18

3x = 30

x = 10

Find the total amount<br> $16.000 at 14% compounded<br> semiannually for 2 years
Liono4ka [1.6K]

Answer:

The answer would be 20.97273616 or (rounded to the nearest cent) would be $20.97

Step-by-step explanation:

The reason for this is that the formula for compounded interest is A=P(1+\frac{r}{n})^\frac{t}{n} where A is the total amount, P is the initial amount, r is the growth factor or the percent, n is the number of compounding periods, and t is the time. You would substitute P for 16, r for 0.14 (14%), n for 2 as it compounded semiannually so it for every 6 months instead of 1 year (annual) so is compounded 2 times per year, and t for 2. And just solve the equation and you get that A is equal to 20.97273616 but since we are talking about money( only round if asked) then it would be 20.97.

Hope this helps!!!!
