1). n+3=8
2). 2-3n=11
3). 1/4+x
4). 2x-1=12
5). 5x = 9x
The numerator should be 8x
Answer: if you simplify this it becomes 30=28 but this is a false statement so you would say 30≠28
Step-by-step explanation:
≠ means not equal
Answer:
22 for num 5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let 
. We have that 
if and only if we can find scalars 
such that 
. This can be translated to the following equations:
1. 
2.
3. 
Which is a system of 3 equations a 2 variables. We can take two of this equations, find the solutions for 
and check if the third equationd is fulfilled.
Case (2,6,6)
Using equations 1 and 2 we get
whose unique solutions are 
, but note that for this values, the third equation doesn't hold (3+2 = 5 
6). So this vector is not in the generated space of u and v.
Case (-9,-2,5)
Using equations 1 and 2 we get
whose unique solutions are 
. Note that in this case, the third equation holds, since 3(3)+2(-2)=5. So this vector is in the generated space of u and v.
