2m + 3b + c + h
m = 8.99, b = 7.47, c = 2.99, h = 29.99
2(8.99) + 3(7.47) + 2.99 + 29.99
17.98 + 22.41 + 2.99 + 29.99
the answer is $73.37 before sales tax

Answer:
10
Step-by-step explanation:
Determinant = ad - bc
![\det\begin{pmatrix} 2 & 0 \\-2 & 5\end{pmatrix} =\begin{vmatrix} 2 & 0 \\-2 & 5\end{vmatrix} = 2\times5 + 0\times2 = 10](https://tex.z-dn.net/?f=%5Cdet%5Cbegin%7Bpmatrix%7D%202%20%26%200%20%5C%5C-2%20%26%205%5Cend%7Bpmatrix%7D%20%3D%5Cbegin%7Bvmatrix%7D%202%20%26%200%20%5C%5C-2%20%26%205%5Cend%7Bvmatrix%7D%20%3D%202%5Ctimes5%20%2B%200%5Ctimes2%20%3D%2010)
(y_final-y_start)/(x_final-x_start) always! :) that easy
(-6-2)/(2-0) = -4
You probably know that if the interval was pretty small, between 0 and 0.0001, it would take you to the concept of slope and derivatives, but average change is just ignoring anything in between x=0, and x=2 (it could go up/down million times, and still the answer would be -4)
hope it helps
