Answer:
<u>The correct answer is B. {-2,4}</u>
Step-by-step explanation:
Let's solve for x, this way:
x + 4/4 = x /x -2
(x + 4) * ((x - 2) = 4 * x
x² - 2x + 4x -8 = 4x
x² - 2x + 4x -8 - 4x = 0
x² - 2x -8 = 0
(x - 4) * (x +2) = 0
x - 4 = 0
x + 2 = 0
x₁ = 4
x₂ = - 2
<u>The correct answer is B. {-2,4}</u>

Try putting it in your calculator. What digit comes next? Any number you pick from 0 to 9 is a guess. That's one of the ways you can tell if a number is irrational or not. You could get the answer from the calculator that came with windows. It gives the answer to 18 digits, but you'd still be guessing the 19th one.
The others are all well behaved in comparison.
Answer: $564
Step-by-step explanation:
You invested $500.
The annual rate is 2% and it is compounded quarterly.
You need the account balance after 6 years.
Convert the terms to their correct periodic figures.
Interest = 2%/4 = 0.5% per quarter
Period = 6 * 4 = 24 quarters
Formula for compound interest:
= Investment * ( 1 + rate) ^ time
= 500 * ( 1 + 0.5%)²⁴
= 563.579
= $564
