It is (-1, 3).
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
x = 7 and 2/3
That factors to (x - 2)(x + 4) x = 2, -4
Exactly (2y + 4) .
4
2x-4
4
x=27
x=7 3/4
x=2
If x/2 +3 = 4 then x = 2
x/(x + 4) = 4/(x + 4) + 2 (x - 4)/(x + 4) = 2 x - 4 = 2x + 8 -x = 12 x = -12
4
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
6
-2
