Determine whether the ordered pair is a solution of the system of linear equations. (-2,-4), y=3x+2,y=-3x-4

no

Step-by-step explanation:

plug them in

-4=3(-2)+2 find if its true

-4=-6+2

-4=-4

do the next one

-4=-3(-2)-4

-4=6-4

-4≠2

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.

the answer is (-4,-4)

hope this ! : d
