The solution to a system of equation is (5,-19). Choose the two equations that might make up the system. y=-3x-6y = − 3 x − 6
y=2x-23y = 2 x − 23
y=-7x+16y = − 7 x + 16
y=x-17y = x − 17
y=-2x-9y = − 2 x − 9

explanation:

huh? im pretty sure it is in 199

step-by-step explanation:

can someone answer this question plz

step-by-step explanation:

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.
