The solution of the system of equations means that following:
1- In case we are dealing with system of equations, the solution would be the point of intersection of the two graphs
2- In case we're dealing with only one equation, the solution would be the points of intersection of the graph with the x-axis
Graph (a):
The graph is for a system of equations (two lines). Therefore, the solution would be the point of intersection of the two lines.
From the graph, we can note that there is only one point of intersection between the two lines (-3,-1). Therefore, the system of equations has only one solution
Graph (b):
The graph is for a system of equations (two lines). Therefore, the solution would be the point of intersection of the two lines.
From the graph, we can note that the two lines are parallel. This means that they will never intersect. Therefore, the system of equations has no solutions
Graph (c):
The graph is for a single line. Therefore, the solution(s) would be the point(s) that make the overall equation equal to zero, i.e. point(s) of intersection with the x-axis.
From the graph, we can note that the line intersects with the x-axis only once at point (2,0). This means that the line has only one solution.
Hope this helps :)

Administration officials say the government has no plans for a new plan for a new president in a long way for the national security to meet the national government for a new plan to stop the government and government officials in a new plan for the president president in a new plan for the president of the country for a new plan for the president of national president in a new national government in a new plan to halt national security and plan for the national security plan to protest against the president and national president of president hun president and national security adviser to the new plan
First find the amount of containers:
6.3 kg/0.35 kg
=18 containers
Now we can find the amount of money earned:
18 containersx$2.99
=$53.82
Bella will earn $53.82 if she sells all the containers.
This is a case of direct variation.
For each hour traveled, the car traveled 50 miles.
d = 50t
1.2 meters = 120 centimeters
amount of increase = 120-80 = 40 centimeters
40 ÷ 80 = 0.5 = 50%
There was a 50% increase.
