R n is a linear combination of vectors ~v1, ~v2, . . . , ~v7 in Rn i… Show more TRUE OR FALSE 10. A vector ~b ∈ R n is a linear combination of vectors ~v1, ~v2, . . . , ~v7 in Rn if and only if the system~v1 ~v2 . . . ~v7 ~x = ~b is consistent. 1. Every vector in R 3 is a linear combination of   0 0 1  ,   0 1 0  , and   1 0 0  . 2. If A and B are matrices with the same row reduced echelon form, then the system A~x = 0 and B~x = 0 have the same number of solutions.​ • Show less
