Use substitution to solve the following system of equations. Show all of your work. Write the solution as an ordered pair.

Answer:

$\left \{ {{x=2} \atop {y=2}} \right.$

Step-by-step explanation:

Substitute the second equation into the first one:

$4x+(2x-2)=10\\6x-2=10\\6x=12\\x=2$

Substitute $x=2$ into the second equation:

$y=2\times 2-2\\y=4-2\\y=2$

$\therefore \left \{ {{x=2} \atop {y=2}} \right.$

Find the median of the data set: -66, -48, -52, -42

olga2289 [7]

-66, -52, - 48, -42

If you can have 2 medians (since there is only 4 numbers), it is -52 and -48

If you can only have one,then i believe you choose -50, because it is in between -48 and -52

hope this helps
