Answer:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.
Answer:
A
Step-by-step explanation:
+7 means go up
if the graph was 7x, the graph enlarges by a factor of 7
About 24 hours per 1 day
8/24=1/3
