Answer:
Step-by-step explanation:
Given


The given system is
can be represented by

The given system is consistent when determinant of A is not equal to zero



i.e. system is consistent for all value of k except 

first you have to find the triangle, then you can move to the actual question.
x+30+80 = 180
x+110 = 180
x+110 - 110 = 180-110
x =70
now you can go to the actual question.
y + 70 = 180
y+70- 70 = 180-70
y = 110
there is your answer. hope this is helpful
I think the answer is 60
idk
Answer:
T.
Step-by-step explanation:
The ordered pair (-2,-1) can also be represented by (x,y). To check the inequality we can substitute the values into the given inequality.




After substituting the values, we then have a clear view that -1 is Greater than -3.1622.
