Y-8x plus 9y equals 10y-8x.
8x plus 4y equals 5 is 8x + 4y = 5.
The roots are: x = 1 and x = 7 So: 7*1 = 7
No.
- 8x + 8x = 0 so question is meaningless.
x^2+8x=20 x^2+8x-20=0 (x+10)(x-2)=0 x=-10 and x=2 are the roots (intercepts) (-10,0) and (2,0) are the x-intercepts.
8x-7 plus 2x equals 6 plus 5x plus 2?
(1, 1)
-8x - 10 - 20 = -8x - 30
x2+8x+9 = -7 x2+8x+9+7 = 0 x2+8x+16 = 0 (x+4)(x+4) = 0 Therefore: x = -4 and also x = -4 (they both have equal roots)
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
I do not believe that there are any rational roots.
