Find the solution of the system of equations.
2x+3y= -4
x + 9y = 13

(-5,2)

Step-by-step explanation:

Using elimination:

Multiply x+9y=13 by -2 which would equal -2x-18y=-26

Then you add the two question together

2x+3y=-4  +  -2x-18y=-26

Since 2x-2x=0, you can cross them out

3y+(-18y)= -15y

-4+-26 =-30

You are now left with -15y=-30

Then you divide both by -15

Your answer is y=2, now you need to find x by plugging y into one of the equations  

x+9(2)=13

x+18=13

Subtract 18 from both sides

x=-5

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
