Solve systems of equations algebraically solve each system of equations algebraically. 1. y=x+2 y=-3x2. y=-x y=-7x3. y=x-6 y=2x4. y=x-4 y=2x5.y=x+20 y=6x

(-1/2, 3/2)
(0,0)
(-4, -8)
(4, 24)

You can get these by setting each right side equal to it's pair. Then solve for x. You can then use your first answer to solve for y. 

Correct sir/miss have a good day x < 3

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
