Solve the system using elimanation: 3x + 5y = -2 and -x + 2y = 8

Step-by-step explanation:

3x+5y+3(-x+2y)=-2+3(8)

3x+5y-3x+6y=-2+24

11y=22

y=2, using this y in -x+2y=8 gives you

-x+2(2)=8

-x+4=8

-x=4

x=-4

So the solution is the point (x, y)=(-4, 2)

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
