Answer:
Between -12 and -13, decimal estimate: -12.2
Step-by-step explanation:
First let's disregard the negative sign, and focus on 
. The smallest square below it is 
, or 144. The greatest square right above it is 
, or 169.
Now we know that is somewhere between 12 and 13. Likewise 
is between -12 and -13. If 12.5 is the square root of 150, it is too high, so we reduce it to 12.2 to 12.3.
Then we can just negate our answer, since we are looking for , to get about -12.2.

Answer:
Step-by-step explanation:
We have to find the system in which we can use the x and y from the given system of equations and make it hold true
From the given equations:
multiply top equation by -2 and add them
so, x = 6, y = 5
A: x-y = 2
6 - 5 = 1, so its not a
B: -2x + 2y = -2
-2(6) + 2(5) = -12 + 10 = -2
B works
just looking at C and D I can tell it doesnt work
So the answer is B
