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.
Is the equation2x2(9x+2-16) if so you would do -16+2 first which is -14
Then multiply 2x2 equals 4
4(9x-14)
Multiply the 4 to 9x and -14
You get 36x-56

Answer:
Solving the inequality we get x>-9.33
The graph is shown in figure attached.
Step-by-step explanation:
We need to solve the inequality: 
Solving:

Switching the sides , reversing the inequality and Multiply 3 with terms inside the bracket

Subtract 6 from both sides

Divide both sides by -3 and inequality will be reversed

Solving the inequality we get x>-9.33
The graph is shown in figure attached.
