Answer:
q= 10
Step-by-step explanation:
9q - 10q = -10
-q = -10
q= -10/-1 = 10
Answer:
h(5) could mean many things
Step-by-step explanation: The h could be a variable and it would mean that h(5) is 5h or h5
Answer:
See proof below
Step-by-step explanation:
We will use the hint. The statement of the hint holds true, as the linear span of a set of vectors T is equal to the set of linear combinations of vectors in T.
Denote the linear span of vectors with the curly brackets < >, that is, 
Let
, then u is a linear combination of v1,v2,v3, that is, there exist scalars
such that
. Multiply by 3 in both sides to get
, with 
Since
,
as real numbers are closed under multiplication. Therefore 3u is a linear combination of the vectors
, that is,
I’m not sure but I think it is
