Graph the system of equations. Then determine whether it has no solution, one solution, or infinitely many solutions. If the system has one solution name it. x – 3y = –3
x + 3y = 9

One solution: (6, -1)

Step-by-step explanation:

I have attached the work to your problem below.

Please see the attachment.

I hope this helps.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
