Answer:
Carmen bought 5 pounds of coffee
Step-by-step explanation:
The cost of buying coffee is $8.44 per pound. Let us assume she bought x pound of coffee, this means that she spent $8.44x on coffee.
She went to the coffee store with $80 gift card and left with $37.80, this means that after spending $8.44x from the initial $80, she had $37.80. To find the number of pounds she bought, we are to use the following equation:
80 - 8.44x = 37.80
8.44x = 80 - 37.80
8.44x = 42.2
x = 42.2/ 8.44 = 5
x = 5 pounds.

The average rate of change of a function f(x) in an interval, a < x < b is given by
Given q(x) = (x + 3)^2
1.) The average rate of change of q(x) in the interval -6 ≤ x ≤ -4 is given by
2.) The average rate of change of q(x) in the interval -3 ≤ x ≤ 0 is given by
3.) The average rate of change of q(x) in the interval -6 ≤ x ≤ -3 is given by
4.) The average rate of change of q(x) in the interval -3 ≤ x ≤ -2 is given by
5.) The average rate of change of q(x) in the interval -4 ≤ x ≤ -3 is given by
6.) The average rate of change of q(x) in the interval -6 ≤ x ≤ 0 is given by
Logically if you double weight on something it means that you are adding the exact same weight as the first object to the same thing to make it twice the weight as the original, so yes... the weight will double if the length is doubled
(z^6 - 8)(z^6 + 8) is the answer.
If you verify this by multiplying, you will see that:
(z^6 - 8)(z^6 + 8) = z^(6+6) + 8z^6 - 8z^6 - 64
= z^12 + 0 - 64
= z^12 - 64
Hope this helps,
