3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
x = 7 and 2/3
y = 3x + 2 y-2 = 3x x = (y-2)/3 So the inverse is (x-2)/3
It is: 3x+10y+5 simplified
-3/2
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
The sum 6 (3x^2) + 8x -3 plus 3 (3x^2) - 7x + 2 = 27 x^2 + x -1
3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
assuming x*2-3x+2:factors of -3:-1,3 --> sum: 21,-3 --> sum: -2(x-1)(x+3)
9x+3
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
If you mean y = 2/3x +3 then it is a straight line equation whereas 2/3 is the slope and 3 is the y intercept
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
It is: 3x^2 +15x +12
3x + 2 = 0 3x = -2 x = -2/3
x = 7 and 2/3
