Step-by-step explanation: (-2,-4)
The expression re-written: 3(2) - 4(3)
First, we multiply (PEMDAS)
3 * 2 = 6
4 * 3 = 12
6 - 12 = -6
Answer: - 6
Given:
Atul has
lb of candy.
Jose has
lb of candy.
Maria has
lb less than Jose.
To find:
How many more pounds of candy does Atul have than Maria?
Solution:
Since, Maria has
lb less than Jose, therefore
Maria has =
lb
Maria has =
lb
Maria has =
lb
Difference between the candies Atul and Maria have.
Difference =
lb
Difference =
lb
Difference =
lb
Therefore, Atul have
lb of candy more than Maria.
Answer:
E is not a subspace of 
Step-by-step explanation:
E is not a subspace of
In order to see this, we must find two points (a,b), (c,d) in E such that (a,b) + (c,d) is not in E.
Consider
(a,b) = (1,1)
(c,d) = (-1,-1)
It is easy to see that both (a,b) and (c,d) are in E since 1*1>0 and (1-)*(-1)>0.
But (a,b) + (c,d) = (1-1, 1-1) = (0,0)
and (0,0) is not in E.
By the way, it can be proved that in any vector space all sub spaces must have the vector zero.
