If you mean 12x+3y = -9 and -8x-2y = 14 then they are y = -4x-3 and y = -4x-7 respectively which means that they are parallel lines because they both have the same slope of -4 but with different y intercepts
The given line has the equation ( y = 12x + 3 ). The slope of this line is 12. Lines that are parallel have the same slope, so the slope of any line parallel to this one is also 12.
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.
y = - 4x - 4
If this is algebra then; 3x plus 12x = 15x

12x-5y+3 = 0 => y = 2.4x+0.6 24x-10y-7 => y = 2.4x-0.292 rounded to 3 d.p. Both lines have the same slope but different y intercepts therefore they are parallel to each other.

y = - 4x - 4
12x-4y+9z+2y =12x-2y+9z
If this is algebra then; 3x plus 12x = 15x
12x+x = 13x
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
Work it out. 5x+3y=3 3y=-5x+3 y=-5/3x+1 -5/3=the slope in this equation -12x+20y=0 20y=12x y=12/20x y=3/5x 3/5=the slope in this equation If the slopes equal each other, the lines are parallel. If they are the negative reciprocal (the fraction flipped upside down and multiplied by -1) of each other, they are perpendicular. I can't believe I just helped someone this lazy.
whats the answer for -2x^3+2^2+12x
10+12x=-14 -14-10=12x 12x=-24 x=-2

8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
