This system has one solution. {y=−2x+4y {=x2+4x+13 what is the y-coordinate of the solution? enter your answer in the box. y =[]

The y-coordinate of the solution is, 10

Step-by-step explanation:

Given the system of equation:

           ....[1]

        ....[2]

Equate the equation [1] and [2] we have;

Add 2x to both sides of an equation:

Subtract 4 from both sides we have;

or

Using perfect square:

⇒We can write the equation as:

then;

⇒

Subtract 3 from both sides we have;

x = -3

Substitute value of x in [1] we have;

⇒

Solution for the given system of equation = (-3, 10)

Therefore, the  y-coordinate of the solution is, 10

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.
