When an amount of money is compounded quarterly, it means that the amount deposited and the interest earns interest every quarter. The formula that can be used to determine the balance in 10 years is:

FV = P (1 + r)^nm

FV = Future value
P = Present value = $1000
R = interest rate = 8%/4 = 2%
m = number of compounding = 4
N = number of years = 10

$1000 x (1.02)^40 = $2,208.04

Y=-3x - 4 <br> y= 2x + 1

Naily [24]

$\left \{ {{y=-3x-4} \atop {y=2x+1}} \right. \\\\ substitution\ method\\\\
-3x-4=2x+1\ \ \ | subtract\ 2x\\\\
-5x-4=1\ \ \ | add\ 4\\\\
-5x=5\ \ \ | divide\ by\ -5\\\\
x=-1\\\\
y=2x+1=2*(-1)+1=-2+1=-1\\\\
Solution:\\ \left \{ {{y=-1} \atop {x=-1}} \right.$
