Mollie and joanne are downloading songs. mollie downloads 34 songs and her computer downloads 5 songs per minute. joanne downloads 78 songs but has an old computer that only downloads 3 songs per minute. how many minutes will it take for them both to have the same amount of songs downloaded.

About 42 minutes for them both to have 78 songs downloaded

Step-by-step explanation:

78 divided by 5 is 15.6 so about 16 minutes

78 divided by 3 is 26 so 26 minutes

so 26 plus 16 is 42

  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).

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
