What is the product?
3•[1,-4,5,-7]

answer:

[3, -12, 15, -21]

which coincides with the first option listed among the possible answers.

step-by-step explanation:

recall that multiplication of a scalar times a matrix involves the product of each of the elements of the matrix times the scalar in question.

so you are supposed to multiply each an every matrix element by the factor "3". this gives:

[3 * 1, 3 * (-4), 3 * 5 , 3 * (-7)] = [3, -12, 15, -21]

which coincides with the first option listed among the possible answers.
