Step-by-step explanation:
Given
a = [tex]\left[\begin{array}{ccc}3\\2\\\end{array}\right][/tex]
To obtain -3a multiply each of the elements of a by -3
3a = [tex]\left[\begin{array}{ccc}-3(3)\\-3(2)\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}-9\\-6\\\end{array}\right][/tex]
To obtain 1.5a multiply each element by 1.5
1.5a = [tex]\left[\begin{array}{ccc}1.5(3)\\1.5(2)\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}4.5\\3\\\end{array}\right][/tex]
