Final answer:
To determine if a vector is in a subspace, we need to check if it can be written as a linear combination of two given vectors.
Step-by-step explanation:
The question is asking if a given vector is in the subspace generated by two other vectors, A and B. To determine this, we need to check if the given vector can be written as a linear combination of A and B. In this case, the given vector can be written as:
v = Ax + By
where x and y are scalars. If we can find values for x and y that satisfy this equation, then the given vector is in the subspace generated by A and B.
So, to answer the question, we need more information about the given vector.
