Answer with Step-by-step explanation:
We are given that
and 
are linearly independent.
By definition of linear independent there exits three scalar 
and 
such that
Where 
We have to prove that 
and 
are linearly independent.
Let 
and 
such that
...(1)
..(2)
..(3)
Because and are linearly independent.
From equation (1) and (3)
...(4)
Adding equation (2) and (4)
From equation (1) and (2)
Hence, and area linearly independent.

Answer:
Because the price did not stay the same when they discounted it by 10% percent before.
Step-by-step explanation:
10% percent of 450 is 45 so Subtracting that from 450 would give you,405.
They deducted another 10% percent a week later 10 percent of 405 would be 40.5 so you would subtract that from 405 which would make it 364.5
If you took 20% off originally then 20% of 450 is 90 so subtracting that would make 450 into 360 which is different from 364.5
