2) Consider the parabola whose focus is (0,8) and directrix is y = 2 a) Determine the vertex of the parabola.

b) Write the equation of the parabola in vertex form.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
