Use addition to solve the linear system of equations. include all of your work in your final answer.
-x-y=4
x+2y=4

The solution is the point (-12,8)

Step-by-step explanation:

we have

-x-y=4 > equation A

x+2y=4 > equation B

Adds equation A and equation B and solve for y

-x-y=4

x+2y=4

-y+2y=4+4

y=8

Find the value of x

x+2y=4

x+2(8)=4

x=4-16

x=-12

therefore

The solution is the point (-12,8)

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
