Which is true of the standard form of the equation of the line graphed? A) The value of A can be –1 if the value of C is 3 and the value of B is 0.
B) The value of A can only be 1, the value of C can only be –3, and the value of B is 0.
C) The standard form of the equation can be shown as 3x = –9.
D) The standard form of the equation can only be x + 3 = 0.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

What can we do about it
