Question

Can you help me simplify the 2 problems below involving matrixe?

1. [4 5] +2 [1 8]
[0 -1] [-4 -6]

2. -0.5 [10 8]
[-2 -6]

Answer 1

what the problem, looks straightforward to me

Answer 2

I don't understand how in the 1st problem there is a (+2), what am going to do with that...?

and the 2nd one...Am i suppose to multiply the -0.5? I am not sure

Answer 3

yes for the first one, you are told to add one matrix to twice the other matrix, meaning that for the matrix that has the 2 by it, you should multiply all the entries in that matrix by 2, and then add it to the other matrix

Answer 4

and for the second problem, you are also correct, you are to simply multiply each entry in that matrix by -1/2 or -0.5

Answer 5

\[you're\:a\:\bigstar\]

Answer 6

Okay so I was able to answer #2 but I am still having trouble with #1, I understand what you're saying but the answer that I come up with doesn't fit any of the multiple choices...

My answer:
[9 18]
[-4 -8]
