Answer:
( -1,-2)
Step-by-step explanation:
x + y = -3
x - y = 1
Add the two equations together to eliminate y
x + y = -3
x - y = 1
------------------
2x = -2
Divide by 2
2x/2 = -2/2
x = -1
Now find y
x+y =-3
-1 +y = -3
-1+1 +y = -3+1
y = -2
( -1,-2)
Part A. It is non linear because it can't make straight line.
Part B. In the graph▼
A is increasing,
B is Constant,
C is decreasing,
Part C. A is Increasing by the (0 to 16) because it is in upward and B is constant because it is (16 to 16) it is in same level then C is decreasing by the (16 to 0) because it is in downward.
I hope you understand....
Thanks....
Make me as brainliest....
the greatest possible error for meters is 1/2 the increments
since 18.9 is to the tenths place
1/2 x 1/10 = 0.05
so greatest possible error for 18.9 is 0.05m
