Answer:
(a) The system of the equations  has no solution.
 has no solution.
(b) The system of the equations  has many solutions
 has many solutions 
Step-by-step explanation:
(a) To find the solutions of the following system of equations  you must:
 you must:
Multiply  by 2:
 by 2:

Subtract the equations

0 = -3 is false, therefore the system of the equations has no solution.
(b) To find the solutions of the system  you must:
 you must:
Isolate x for 

Substitute  into the second equation
 into the second equation

The system has many solutions.
Isolate y for 

 
        
             
        
        
        
2 2/3 = 2x3+2/3 = 8/3
8/3 / 1/3 = 8/3 x 3/1 = 8/1 = 8

Answer:
Graph D
Step-by-step explanation:
Initially, Marlon was looking for his pump. Thus, no air was pumped into the balloon until he got the pump. On getting the pump, he inflated the balloon with air at a constant rate, after which he tied it with a string to prevent the air from escaping.
The analysis is that, at the time he decided to inflate the balloon till he got a pump, the volume of air in the balloon is zero with respect to time. Pumping air at a steady rate into the balloon increases the volume of air flowing into it gradually and steadily.
When the volume got to a definite amount, he stopped pumping air and tied with a string. Thus, the volume of air in the balloon remains constant.
