To solve this, you'll need the interest formula: <span> P(1 + rt).
Then, plug in the numbers:
$500(1.08*3) = $1,620. That's your answer.</span>
-(-5 - 6x) = 4 (5x +3)
Pretend that there is a -1 in front of the first bracket
-1(-5-6x)= 4(5x+3)
Mutiply the first bracket by -1
(-1)(-5)(-1)(-6x)= 5+6x
Mutiply the second bracket by 4
(4)(5x)(4)(3)= 20x+12
5+6x= 20x+12
move 20x to the other side
5+6x-20x= 20x-20x+12
5+6x-20x= 12
5-14x= 12
move 5 to the other side
sign changes from +5 to -5.
5-5-14x= 12-5
-14x=7
divide by -14
-14x/-14= 7/-14
x= -1/2
Answer: x= -1/2
For f(10) replace x with 10 then solve:
f10) = 10^2 + 1
= 100 +1
= 101
Answer:
balance after 4 years = $4502
Step-by-step explanation:
Formula to get the final amount when compounded annually is,
Final amount = 
Here, r = rate of interest
n = number of compounding per year
t = Duration of investment
From the given question,
Final amount = 
= 
= 4502.0352
≈ $4502
Therefore, balance after 4 years = $4502
