What is the equation of a parabola whose vertex is (0, 5) and whose directrix is x = 2? y2 = 8(x − 5) 8(y − 5) = x2 (y − 5)2 = 8x (y − 5)2 = -8x

Step-by-step explanation:

vertex is (0, 5) and whose directrix is x = 2

Vertex (0,5), x=0 and y=5

The distance between x=0 and x=2 is 2 units

The distance between vertex and directrix is P

p= 2

General equation of horizontal parabola is

h=0, y= 5, p=2

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
