20 children went to a cafe for lunch.14 children ate fish burgers. 10 children ate chicken burgers. how many children ate both fish and chicken burgers?

If there are 20 children that went to eat lunch, and 14 of them ate fish burgers, and 10 ate chicken burgers, you could make a line graph with 20 points and color the kids who ate fish burgers yellow and the one who ate chicken burgers blue. The green where they overlapped, and 10 of them over lapped, meaning that 10 children ate both fish and chicken burgers.  Hope I helped!

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
