Answer:
y= -x
y= 3/2 -5
Step-by-step explanation:
The sum of two numbers is zero.
x + y = 0
y = -x
Twice the smaller number subtracted from 3 times the larger number is 10.
Let x represent the larger number and y represent the smaller number.
Twice the smaller number: 2y
3 times the larger number: 3x
Twice the smaller number subtracted from 3 times the larger number is 10.
3x - 2y = 10
-2y = -3x + 10
y = 3/2 x - 5
The equations are:
y = -x
y = 3/2 x - 5

To answer this question you will need to be able to calculate compound interest. The following formula can be used to do this:
A = P(1 + r/n)^nt
A stands for the amount you will have after a period of time.
P stands for the Principal; $1750 in this case
r/n stands for the rate over the number of times the interested is compounded per year (in your case, it will be 0.0425/1)
^nt stands for "to the power of" the number of years you will be compounding the interest. In this case it is 15
Let's put it all together:
A = 1750 (1+0.0425/1)^15
A = $3267.22 is approximately the new amount after 15 years
$3267.22-$1750 = $1517 is the interest accrued
