Lily invested $750 in a savings account and earned $225 in interest at the end of 5 years.
slava [35]
After 5 years Lily has $750+$225 = $975
The equation for interest rate looks like:
750 * x^5 = 975 
x^5 = 975/750
x^5 = 1.3
x = \sqrt[5]{1.3}
x = 1,0538
That means that interest rate is approximately 5,5% (B)

The reason for this calculation is because each year you multiply your money with interest rate and add that to your starting money.
After one year you will earn
750 + 750 * interest rate = money after 1 year.
After 5 years we multiply 5 times so our interest rate is x^5 and money after 5 years is 750 + 225.

Q8 Q3.) Solve the system by the substitution method.
inn [45]
Recall that (x+y)^2=x^2+2xy+y^2. So we can add twice the first equation to the second one to get

x^2+y^2+2xy=10+2\cdot3\iff(x+y)^2=16\implies x+y=\pm4

Since xy=3, we have y=\dfrac3x (x\neq0) so

x+y=x+\dfrac3x=\pm4\implies x^2\mp4x+3=0

If x+y=4, then

x^2-4x+3=(x-3)(x-1)=0\implies x=3,x=1\implies y=1,y=3

If x+y=-4, then

x^2+4x+3=(x+1)(x+3)=0\implies x=-1,x=-3\implies y=-3,y=-1

So the solution set is

(x,y)\in\{(-3,1),(1,3),(-1,-3),(-3,-1)\}
