On any circle, which of these would have the greatest measure? Radius, Chord, Diameter, Circumference.

 The Circumference of a circle has the greatest measure.

Step-by-step explanation:  A chord connects two points on a circle that are shorter than the diameter. The diameter is the measure across the widest part of the circle.

Circumference is the perimeter of the circle, the distance all the way around. It is π × diameter-- a bit more than 3 times the length of the diameter.

Step-by-step explanation:

3x+y=-4   (1)

3x-4y=6  (2)

solving by elimination:

(1) - (2) ⇒

3x + y  = -4

3x - 4y = 6

________

0 + 5y  = -10

5y = -10 ⇔ y = -2

(2) ⇒ 3x-4y=6  ⇒ 3x-4(-2)=6  ⇒ 3x = 6 - 8 = -2 ⇒ x = -2/3
