Is this equation 9x plus 3y equals 12 and 12x plus 4y equals 18 parallel?
Yes the equation is parallel and this is why.... when you put the formula 9x+3y=12 in a slope intercept form you'll get 9x+3y=12 9x+3y-12=0 3y= -9x+12 divide by 3 y=-3x+4 12x+4y=18 12x+4y-18=0 4y= -12x+18 divide by 4 y= -3x + 9/2 In order for two equations to be parallel the slope must be equal to each other remember the slop is the m in y=mx+b. Since both equations have -3 as it's slope that makes them parallel lines.
What is the equation of a line that is parallel to 3y equals -12x plus 9 and that has a y-intercept of -4?
y = - 4x - 4

x2+12x+28Improved Answer:--x2+12x+28 = (-x+14)(x+2) when factored
What is the answer to 8x-3 plus 6x-1 equals 12x plus 6?
8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
