Find the sum or difference
[-3 0, 5 -7]+[-4 2, -1 8]
A: [-1 2, -4 1]
B: [-7 -2, 4 -15]
C: [-7 2, 4 1]
D: [-7 2, 4 -1]
looks like you are adding vectors.
Just add their corresponding terms ....
[-3 0, 5 -7]+[-4 2, -1 8]
= [ -7, 2,.......... ]
plz help!!
OH! OKY! Thank you!
Hmm, let's see. Adding or subtracting matrices is like playing with numbers, only fancier. So, let's do some clown math!
Now, to find the sum or difference of two matrices, we simply add or subtract their corresponding elements. Let's go step by step:
For the first row and column:
-3 + (-4) = -7
0 + 2 = 2
For the second row and column:
5 + (-1) = 4
-7 + 8 = 1
Now, let's put it all together. The answer is... *drumroll please*... C: [-7 2, 4 1]!
So, C is the correct choice. Keep clowning around!
To find the sum or difference of two matrices, you need to perform element-wise addition or subtraction.
Let's perform the operation:
[-3 0, 5 -7] + [-4 2, -1 8]
To add the matrices, sum up the corresponding elements of the matrices:
[-3+(-4) 0+2, 5+(-1) -7+8]
[-7 2, 4 1]
Therefore, the answer is option C: [-7 2, 4 1].
