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.
I got you, the answer would be x=5
Answer:
y = 6x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
y - 5 = 6(x + 1) ← distribute
y - 5 = 6x + 6 ( add 5 to both sides )
y = 6x + 11 ← in slope- intercept form
