I need help to write and solve equations Toni can carry up to 18 lb in her backpack. Her lunch weighs 1 lb, and her books (b) weights 3 lb each. How many books can she carry in her backpack?

5 books

Step by step explanation:

With her lunchbag in her backpack she can carry 17 pounds. 3×5 is 15 and 15 is the highest we can go without passing 17. She can carry 6 if she does NOT bring her lunch bag

  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).
