Answer: x=5 y=-6
(5,-6)
Step-by-step explanation:
Solve by elimination
multiply x-5y=35 by 3
= 3x-15y=105
-
divide 9 on both sides
y= -6
Now solve for x
you must plug in -6 for y in either equations
i plugged in -6 for y in 3x-15y=105
subtract 90 on both sides

APR = Annual Percentage Rate; APY = Annual Percentage Yield.
This is a tough question!!
To get the APY we use the compounding formula (A = P(1+r/n)^nt) and put $1 in
for the principal and see what our final amount is at 19.07% after a year.
A = 1(1+.1907/12)^12
A= 1.0159^12
A= 1.2083 This means
that we paid 0.2083 on our dollar after a year which means the APY is 20.83%.
If the antique's value increases over time, it must be growing (not decaying) in value.
We're told the value increases by 12.12%, which means that if the current value is
, then the value after 1 year is
. Each year, the value increases by the same factor, which means after 2 years, the value is
; after 3 years, the value is
; and so on.
Here
is the starting value of the antique. So the answer is the second choice.
