Let matrices a, b represent complex numbers. answer the following questions.
a. let a = −b
b a
and b = −
c
show a= b through matrix multiplication.
b. would you expect a = c for any matrix c? explain.
c. let c be any 2 × 2 matrix,
x y
z show a ≠ c through matrix multiplication.
d. summarize your results from problems 3 and 4.

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.

the answer is a if my teacher taught me correct

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
