Answer:
any thing, not 1 or -1
Step-by-step explanation:
the equality to any number is either itself or its opposite 1 inequality would be 2-infinite or -2- -infinite and zero
Using compound interest, it is found that:
- The equation is:
- After 3 years, he has $4,252 in the account.
- After 10 years, he has $6,608 in the account.
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:
In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
- t is the time in years for which the money is invested or borrowed.
In this problem:
- Jack was given $3520 from his grandma, hence P = 3520.
- The account pays 6.5% interest rate that is compounded annually, hence n = 1, r = 0.065.
Hence, the equation is:
After 3 and 10 years, respectively, the amount in dollars in the account are given by:

Your answer is going to 3/2i
Answer:
x = 1/3 or -2
Step-by-step explanation:
2x^2 + 7x - 2 = - x^2 + 2x
3x^2 + 5x - 2 = 0 (use factoring)
(3x − 1)(x + 2) = 0
3x - 1 = 0 OR x + 2 = 0
3x = 1 x = - 2
x = 1/3
