Consider the matrices. What is the product of matrix PQ?

Answer:
Step-by-step explanation:
P = [tex]\left[\begin{array}{ccc}2&7\\3&0\\5&4\\-1&-3\end{array}\right][/tex]
Q = [tex]\left[\begin{array}{ccc}-4\\-3\end{array}\right][/tex]
PQ = [tex]\left[\begin{array}{ccc}2(-4)+7(-3)\\3(-4)+0(-3)\\5(-4)+4(-3)\\-1(-4)+(-3)(-3)\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-29\\-12\\-32\\13\end{array}\right][/tex]
