Answer: The interest is $453.60.
The total amount includes principal + interest. The principal was 630 and the total amount was 1083.60.
1083.60 - 630 = 453.60.
Step-by-step explanation:
This is a strange question, and f(x) may not even exist. Why do I say that? Well..
[1] We know that f(a+b) = f(a) + f(b). Therefore, f(0+0) = f(0) + f(0). In other words, f(0) = f(0) + f(0). Subtracting, we see, f(0) - f(0) = f(0) or 0 = f(0).
[2] So, what's the problem? We found the answer, f(0) = 0, right? Maybe, but the second rule says that f(x) is always positive. However, f(0) = 0 is not positive!
Since there is a contradiction, we must either conclude that the single value f(0) does not exist, or that the entire function f(x) does not exist.
To fix this, we could instead say that "f(x) is always nonnegative" and then we would be safe.
Answer:
<u>x = 5</u>
Step-by-step explanation:
Equating the terms :
Add 2 on both sides :
- x + 3 + 2 = 2x - 2 + 2
- x + 5 = 2x
Subtract x from both sides :
- x + 5 - x = 2x - x
- <u>x = 5</u>
If by bivariate data you mean data in charts or any type of collection of data, the data's would be proportional and would be a straight line and go through the origin in a coordinate plane.
