Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.

Answer:
4.7 pi
Step-by-step explanation:
Length of arc AB = radius of the circle × theta(in radians)
Length of the arc = 6 × theta
Theta in radians = 140/180 × pi
Theta = (7/9)pi
Length of arc AB = 6 × (7/9)pi
Length = (42/9)pi
Length = 4.7 pi
