Alright, let get started.
Suppose the initial deposit in account = x
After five years, this accounts get doubled means = 2x
Means in 5 years , the growth =
So, in 1 year, the growth will be =
So, in 3 years, the growth will be =
So percent grwoth will be =
Hence percentage growth is 60 %. : Answer
Hope it will help :)
Answer:
A) Quantity x minus 5 over quantity x plus 1, where x≠-1 and x≠-9
Step-by-step explanation:
Simplifying the numerator first:
x² + 4x - 45 using the quadratic formula you get;
(x - 5)(x + 9)
Then simplifying the denominator x² + 10x + 9 using a quadratic formula you get;
(x + 1)(x + 9)
Dividing the numerator and denominator now gives;
Cancelling (x + 9) throughout leaves you with;
The only restrictions here is if x = 1 and 9 which will give an undefined answer.
