Answer:
(1,2) and (2,-1)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line 
---->inequality B
The solution of the inequality B is the shaded area above the dashed line 
The solution of the system of inequalities is the triangular shaded area between the two dashed lines
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area
Two points in the solution are(1,2) and (2,-1)see the attached figure
Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: 
Then, solve:
a = -2
So yes, they're on the graph.
Hope this helped! :)
Answer:
Length • Width
20 • 25 = 500
So the area is 500ft! :)
Step-by-step explanation:
Answer ≈ 4 and a half billion
If we assume your letters range from A to Z and your digits from 0 to 9, you have 26 possibilities per letter and 10 per digit. This gives you 26^4*10^4 which is roughly 4 billion and a half.
I do belive the first one is 30
