The distance between the parallel planes ax + by + cz + d1 = 0 and ax + by + cz + d2 = 0 is d = |d1 − d2| a2 + b2 + c2 . find equations of the planes that are parallel to the plane x + 2y − 2z = −1 and two units away from it. (enter your answers as a comma-separated list of equations.)

Each equation given below describes a parabola. which statement best compares their graphs? x = 2y^2 x = 8y^2

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.
