FINISH THE LYRICS!!

I cannot explainwhy things so easily break and the longer im here ,,

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

3x = 729 solve for x plz . it's urgent. will mark
