Why are there two solutions for the equation |6 + y| = 2? explain.

Here is what I wrote:

There are two solutions for |6+y|=2, -8 and -4.

This is because |6+(-8)| and |6+(-4)| both equal 2.

The absolute value is the distance to zero on a number line.

If one were to graph the equation there would be a line with two different directions to determine distance from 0.

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.
