3x-4y= -24 and x+y= -1 using elimination

The solution set would be (-4, 3)

Step-by-step explanation:

To find this, we need to multiply the second equation by 4. Then we can add through.

3x - 4y = -24

4x + 4y = -4

7x = -28

x = -4

Now that we have the value of x, we can solve for y.

x + y = -1

-4 + y = -1

y = 3

idk the answer but just put a

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.
