6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
0.2x + 6x - 1 = -9 6.2x = -8 x = -1.2903225806451612903225806451613
8x^3 - 12x^2 + 6x - 9 = (8x^3 - 12x^2) + (6x - 9) = 4x^2(2x - 3) + 3(2x - 3) = (4x^2 + 3)(2x - 3)
6x+3y = -9 3y = -6x-9 y = -2x-3 Therefore the perpendicular slope is 1/2
Put in function, Y = mX + C, form. 6X + 3Y = - 9 3Y = - 6X - 9 Y = - 2X - 3 -------------------- m(slope) = - 2 ----------------------
6x + 9 + 2x = 8x + 9
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
6x - 9 + 2x + 1 = 8x -8
5x + x - 6x + 2x = 2x
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
2x+9=6x-3 Therefore 4x=12 -->x=3
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
2x+92+6x
2x+6x=-9 => 8x=-9=> x=-8/9
8x-9 -2x plus 11 when solved mathematically is equal to 6x + 2.
x + 2x + 6x = 9x
