The system of equations:
2 y = - x - 1
2 y = x + 5
---------------------
- x - 1 = x + 5
- 2 x = 5 + 1
- 2 x = 6
x = - 6 : 2
x = - 3
2 y = - 3 + 5
2 y = 2
y = 1
The solution is ( - 3 , 1 ).
Answer: The x-coordinate of the solution to the system is: x = - 3.
Answer:
Option B.
Step-by-step explanation:
The given formula is

It is given that a line segment has endpoints Q at –8 and S at 12. Point R partitions the directed line segment from Q to S in a 4:1 ratio. It means




Substitute these values in the given formula.

Therefore, the correct option is B.
