Answer:
-4
Step-by-step explanation:
The average rate of change of a function f(x) between two points x = a and x=b is given by,
This can be understood with a simpler example, the straight line.
In this case, the rate of change of the 'function' is given by the slope,
;
being two points on the straight line.
So, for the given problem,
a = -2
b = 2
Hence, average rate of change of 
Step-by-step explanation:
Simply input 3 for x in the equation.
The answer is D because the additional 120 for the remaining six months only brings them to 9900. An additional month brings them to a total of 9690.
5x and 6x are like terms because they are both followed by an x. 20 and -13 are also like terms. For they have nothing behind them. Hope this helps!
