The graph for the equation y=-x+2 is shown. if another equation is graphed so that the system has an infinite number of solutions, which equation could that be?
a. y=-2(x-1)
b. y=-(x+2)
c. y=-1/4(4x-8)
d. y=-1/2(x+4)

C

Step-by-step explanation:

Note that C is exactly -1/4(4x-8) = -1/4*4x -1/4*(-8) = -x+2, so the system with C is the same equation twice, and obviously has an infinite number of solutions.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
