The numbers:  x, y
x·y=-14
x+y=5    ⇒    y=5-x
Substitute y in the first equation by y from second one
x·(5-x)=-14
5x-x²=-14
-x²+5x+14=0
-x²-2x+7x+14=0
-x(x+2)+7(x+2)=0
(x+2)(-x+7)=0
Product is 0 if one of factors is 0
x+2=0      or        -x+7=0
x=-2         or         -x=-7
x=-2         or           x=7
Now back to the equation y=5-x
y=5-(-2)    or     y=5-7
y=7           or     y=-2

The numbers are -2 and 7

A bank pays 5% interest compounded annually. What principal will grow to $12,000 in 10 years.
makvit [3.9K]
<h3>Answer: 7366.96 dollars</h3>

========================================================

Use the compound interest formula:

A = P(1+r/n)^(n*t)

where in this case,

A = 12000 = amount after t years

P = unknown = deposited amount we want to solve for

r = 0.05 = the decimal form of 5% interest

n = 1 = refers to the compounding frequency (annual)

t = 10 = number of years

-------

Plug all these values into the equation, then solve for P

A = P(1+r/n)^(n*t)

12000 = P(1+0.05/1)^(1*10)

12000 = P(1.05)^(10)

12000 = P(1.62889462677744)

12000 = 1.62889462677744P

1.62889462677744P = 12000

P = 12000/1.62889462677744

P = 7366.95904248911

P = 7366.96
