To solve this we are going to graph each one of the system of equations. The points in which the graphs of the tow equations intercepts will be the real solutions of the system of equations.
System A. Since the graph of the equations intercepts two times, we can conclude that the system has 2 real solutions.
System B. Since the graph of the equation don't intercept, we can conclude that the system has 0 real solutions.
System C. Since the graph of the equations intercepts two times, we can conclude that the system has 2 real solutions.

Answer:
286 possible outcomes.
Step-by-step explanation:
We have been given total 13 identical marbles
We need to select 10 out of 13
We will use combination:
here,n=13 and r=10 on substituting the values in the formula we get:
So, there are 286 possible outcomes.
