Answer:
Observe that if the vector is in W then it satisfies:
This means that each vector in W can be expressed as a linear combination of the vectors
Also we can see that those vectors are linear independent. Then the set
is a basis for W and the dimension of W is 2.
Answer:
11/4 or 2 3/4
Step-by-step explanation:
add numerators keep the same denominator
You just have to add one eqaution to another :
-x + x -y + 2y = 7 + 7
y = 14
Then apply y = 14 to one of the equations :
eg: x + 2(14) = 7
x + 28 = 7
x = - 21
The awnser is x= -21 y= 14
I hope i awnsered your question
