Find parametric equations for the line. (enter your answers as a comma-separated list of equations. let x, y, and z be functions of t.) the line in the direction of the vector 5 i + 5 j − 6k and through the point (−4, 4, −2).

What is the equation of the graph below? y=sec(x)-4

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3
