Find the inverse of each of the given functions.
f(x) = 4x - 12
f1x) =
x+

If a(0,0,0) and b(2,2,2) are points in coordinate space, how many paths are there from a to b that move from one lattice point to another in the positive x-,y- or z- direction?

Just tell me how to set up the equation.

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180
