Question

Use the given matrices to compute the given expression.
-Let A  Find 4A + B.

Quizplus · Accepted Answer

To compute 4A + B, we need to perform the scalar multiplication on matrix A by 4 and add matrix B element-wise to the resulting matrix. This gives:
4A + B = 4 * [1 7; 0 -4] + [-1 2; 3 0] = [4 30; 0 -16] + [-1 2; 3 0] = [3 32; 3 -16]
Therefore, the answer is choice A.
