Question

If a = (3, 2) and b = (-5, 3), what is a + b ?
(8,-1)
(2,5)
(-2,5)
(8,5)

Answer 1

Answer: a + b = (-2,5)

Step-by-step explanation: I'm assuming that these are 1-dimensional matrices or vectors.

So,

a + b = [ a(x) + b(x), a(y) + b(y) ]

= [ (3) + (-5) , (2) + (3) ]

= [ (-2) , (5) ]

a +b = (-2,5)
