Answer:
y = 2x + 11
Step-by-step explanation:
y - 3 = 2(x + 4)
y - 3 = 2*x + 2*4
y -3 = 2x + 8
y = 2x + 8 +3
y = 2x + 11
Answer:
A. 11
Step-by-step explanation:
The average rate of change of the given function over the interval [2,6] is simply the slope of the secant line connecting the point (2,f(2)) and (6,f(6)).
This implies that, the average rate of change over [2,6]


From the table f(6)=71
Since we want the average rate of change to be 15, we have;

This implies that;





The correct choice is A.
It is called a point of concurrency
5 for 3.50 because then it would cost 0.70 for each.
