Answer:
The system of equations has no solutions
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously;
-2 = -y - x
y = -1 - x
Substitute the second into the first
-2 = -(-1-x) - x
-2 = 1 + x - x
We can see that the system has no solutions

Answer:
20 m per second
Step-by-step explanation:
100 / 5 = 20
Answer:
Midpoint of AB = (0 + 2a / 2 , 0 + 0 / 2) = (2a / 2 , 0 / 2) = (a,0)
x coordinate of point c = a
N = (0 + a / 2 , 0 + b / 2) = (a / 2 , b / 2)
M = ( 2a + a / 2 , 0 + b / 2) = (3a / 2 , b / 2)
MA = √(3a / 2 - 0)² + b / 2 - 0)²
= √(3a / 2 )² + (b / 2) = 9a² / 4 + b² / 4
NB = √(a / 2 - 2a)² + (b / 2 - 0 )²
= √( a / 2 - 4a / 2)² + (b / 2 - 0)²
= √(-3a / 2)² + (b / 2)² = √9a² / 4 + b² / 4
