Find the standard form of the equation of the parabola with a focus at (0, -6) and a directrix at y = 6. y2 = -24x
y = negative 1 divided by 6x2
y2 = -6x
y = negative 1 divided by 24x2

2x + 1 < 5 solve the following inequality. then place the correct number in the box provided.

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

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
