Find the distance from the point to the given plane. (−8, 7, 6), x − 2y − 4z = 8

The system of equations graphed below has how many solutions?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

The volume of a sphere is increased by 6%. calculate the corresponding percentage increased in it area.
