Answer:
I've shown the process in the picture .
hope u understand
1. A
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
Answer:
BC = 25
Step-by-step explanation:
AB = AC since it is an isosceles triangle
4x+1 = 2x+23
subtract 2x from each side
4x-2x+1 = 2x-2x+23
2x +1 = 23
subtract 1 from each side
2x+1 -1 = 23-1
2x = 22
divide by 2
2x/2 =22/2
x =11
BC = 3x-8
BC = 3(11) -8
BC =33-8
BC = 25
