Which of these systems of equations has an infinite number of solutions?
(A)–6c + 11d = 20
– 6c + 11d = 20

(B)-6c + 11d = 20
– 50 + 8d = 22

(C)–6c+1ld = 22
– 50 + 8d = 22

(D)–50 + 8d = 20
– 50 + 8d = 22

the first one, all those points on the line just make a strait line.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

it is not that hard all u have to do is plot the graph

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
