Below are sample questions representative of the exercises included on this worksheet and related ALG2.229 Matrix Addition, Scalar Multiplication, and Multiplication (Extension) skill assessments:

Problem 1Difficulty: Mastery
Let A = [[2, -1, 0]; [1, 3, 4]] and v = [[x]; [2]; [-1]]. If Av = [[4]; [5]], what is x?
A2
B5
C-3
D3
Solution & Explanation:The first entry of Av is 2x - 1(2) + 0(-1) = 2x - 2. Since this equals 4, 2x = 6 and x = 3. The second entry also checks: 3 + 6 - 4 = 5.
Problem 2Difficulty: Mastery
Which statement is always true for matrices with compatible dimensions?
AAB = BA
BA + B is defined whenever AB is defined
CA(B + C) = AB + AC
DEvery matrix product has the same dimensions as its factors
Solution & Explanation:Matrix multiplication distributes over matrix addition when the dimensions are compatible. The other statements are not always true because multiplication is not generally commutative and dimensions must be checked separately.
Problem 3Difficulty: Mastery
Which matrix equation represents the system 4x - y = 9 and 2x + 3y = -1?
A[[x, y]][[4, -1]; [2, 3]] = [[9, -1]]
B[[4, -1]; [2, 3]][[x]; [y]] = [[9]; [-1]]
C[[4, 2]; [-1, 3]][[9]; [-1]] = [[x]; [y]]
D[[4, -1, 9]; [2, 3, -1]][[x]; [y]] = [[0]; [0]]
Solution & Explanation:The coefficient matrix stores the x- and y-coefficients by row, the variable vector is [[x]; [y]], and the constant vector is [[9]; [-1]].
