Assume all vectors are in R^n. Mark each statement True or False. Justify each answer. a. Not every orthogonal set in is linearly independent.
b. The orthogonal projection of y onto v is the same as the orthogonal projection of y onto cv whenever c ≠ 0
c. An orthogonal matrix is invertible.

18a

step-by-step explanation:

simply because it is. it's the highest common factor

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

i think the answer is b
