Answer:
Not a subspace
Step-by-step explanation:
(4,0,0) and (0,4,0) are vectors in R3 with zero or one entries being nonzero, but their sum, (4,4,0) has two nonzero entries.
-4x +4 = -3x + 31
4 - 31 = -3x + 4x
-27 = x
Part A: slope is 40
And i don’t know the rest I’m sorry
B agree
A,c, d don’t make sense
