Answer:

x = 4, y =3

Step-by-step explanation:

4x − 6y = −2

−2x + 12y = 28

Multiply the first equation by 2

8x -12y = -4

Add the second equation to this

8x -12y = -4

−2x + 12y = 28

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

6x + 0y = 24

Divide each side by 6

6x/6 = 24/6

x = 4

Now we find y

4x- 6y = -2

4(4) - 6y = -2

16 -6y = -2

subtract 16 from each side

16-16 -6y = -2-16

-6y = -18

Divide by -6

-6y/-6 = -18/-6

y = 3

A series of equal quarterly payments of $10,000 for 15 years is equivalent to what future worth amount at an interest rate of 6%
kogti [31]

Answer:

  $976,578.71

Step-by-step explanation:

We assume the deposits are made at the <em>beginning</em> of each quarter. The quarterly interest rate is 6%/4 = 1.5%. The number of quarterly payments is 15×4 = 60. The future value of an annuity due is ...

  A = P(1+r)((1+r)^n -1)/r

where r is the quarterly interest rate, n is the number of payments, and P is the payment amount.

  A = $10000(1.015)(1.015^60 -1)/.015 ≈ $976,578.71

The future value is $976,578.71.
