Question

Which of the following systems of equations has infinitely many solutions:

A. (6x-5y=11; 10y=9x-22)
B. (8x-4=6y; 12y-8=4x)
C. (4x-7y=4; 14y=8x-8)
D. (5y=-6x-4; 12x+15y=8)

Answer 1

they represent st.lines.......they infinte solutions if they overlap.......it means they shud represent the same line...........now can u try?

Answer 2

i have no idea what you mean

Answer 3

ok check c
14y=8x-8
8x-14y=8
2(4x-7y)=2(4)

Answer 6

choose the one that when you change both equations into y=mx+b form, if they're exactly the same, that' the one you want...

solve for y in each choice... which one is it?

Answer 7
