Solve this system of equations:
2x + 10y= 24
X = y-6

(-3,3)

Step-by-step explanation:

Substitute x for the first equation

2(y-6) + 10y= 24

2y-12+10y=24

12y=36

y=3

Now solve for x by plugging in 3

x = 3-6

x=-3

x = -3

y = 3

Step-by-step explanation:

2x + 10y = 24

x = y - 6

plugin x = y - 6 into the first equation

2(y - 6) + 10y = 24

solve for y

2y - 12 + 10y = 24

12y = 36

y = 3

plug y back into x = y - 6

x = 3 - 6

x = -3

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.
