The slope is 0.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
4x+7=9x+7 -5x=0 x=0
Factors are (2x + 1)(x + 4), making x either -0.5 or -0.25
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
5*2+9x-2=0 so, going by BODMAS rule 10+9x-2=0 9x=-10+2 9x=-8 x=-8/9 I think!!
6x2 + 9x = 0 3x(2x + 3) = 0 3x = 0 or 2x + 3 = 0 x = 0 or x = -3/2
