X=-1
Step-by-step explanation:
3 • (x + 2) - (1 - 2x) = 0
5x + 5 = 5 • (x + 1)
5 • (x + 1) = 0
5 = 0
x+1 = 0
x = -1
At x=2, y=4
At x=4, y=16
So the total change in y from x=2 to x=4 is 16-4=12
And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6
Hope that helps. Let me know if you have any questions.
C. -14x
Just multiply 3 with -5 and get -14x. And then add a positive x to get -14x
