Osh and his friends bought vanilla wafers for $4 per packet and chocolate wafers for $1 per packet at a carnival. they spent a total of $45 to buy a total of 27 packets of wafers of the two varieties. part a: write a system of equations that can be solved to find the number of packets of vanilla wafers and the number of packets of chocolate wafers that josh and his friends bought at the carnival. define the variables used in the equations. (5 points) part b: how many packets of chocolate wafers and vanilla wafers did they buy? explain how you got the answer and why you selected a particular method to get the answer.

  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).

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
