Answer:
A, r=9
Step-by-step explanation:
Multiply through by the LCM
r + (3×5) <= 3×8
r + 15 <= 24
r <= 24 - 15
r <= 9
Answer:
D
Step-by-step explanation:
ANSWER
A) -1
EXPLANATION
The average rate of change of the given quadratic function on the interval 0 ≤ x ≤4 is the slope of the secant line connecting the points (0,f(0)) and (4,f(4)).
That is the average rate of change is:

From the graph, f(0) is 0 and f(4) is -4.
We plug in these values to obtain;

This simplifies to;


Hence the average rate of change for the given quadratic function whose graph is shown on 0≤x≤4 is -1
The LCM of 6 and 14 would be 42.
