4... if you plug it in, it works
AC is in the range (2x - 10, 14x + 4)
548
If you mean: y = 6x-4 then the parallel equation is y = 6x+10
4
If: 2x+6x-4 = 52 Then: x = 7
52 = 2x + (6x +4) 52 = 2x + 6x + 4 (can skip this step) 52 = 8x + 4 52 - 4 = 8x 48 = 8x 48/8 = x (can skip this step) 6 = x
-6x
Not enough information. What is the order of P, T and Q? What is the total distance and are the points co-linear?
In 6x + 4 = 12, x = 4/3
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
8x6 plus 4 equals 52.
6x + 2 = 6 6x = 4 x = 2/3
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
x=5
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
