Answer:
3x-3
Step-by-step explanation:
You have to combine like terms. <em>x</em> and 2<em>x</em> have the same variable, so this equals 3x, and then you subtract 3 so:
x-3=2x-3-x
=3x-3
Answer:
input = 5
Step-by-step explanation:
y = -2x - 6
When y = -16
-16 = -2x - 6
divide by -2 on both sides,
8 = x + 3
x = 8 - 3 = 5
A normal vector is the set of coefficients of x, y, and z when the equation is written in standard (or general) form.
Subtracting the left side, we have
... 2(8 -y) -z +5(x -2) = 0
... 16 -2y -z +5x -10 = 0
... 5x -2y -z +6 = 0 . . . . . general form
A normal vector is (5, -2, -1).
