Answer:green area- triangle area = 72-9 = 63
Step-by-step explanation:
4 (2x + 3) + 2 (x + 1) - 7
8x + 12 + 2x + 2 - 7
10x + 7
10x = -7
10x/10 = -7/10
x = -7/10
hope this helps

Step-by-step explanation:
(Also look at image)
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.

Step-by-step explanation:
The rate of change (slope) is 1 which is more than function 2 and less than function 1
