The correct equations of a parabola are z = 2(y-9)²-2 and y = 2(z-2)²-9.
This is a problem with coordinate geometry. We can solve this by following a few steps.
First of all we should know the ideal equation of a parabola. The equation is,
- where ( h, k ) is the vertex of the parabola.
From all those options only last two equations satisfy the conditions.
Where the coordinate of the vertex of this parabola is ( 9, 2 ).
Hence we can conclude that z = 2(y-9)²-2 and y = 2(z-2)²-9 are the correct equation of a parabola.

Answer:
1.35!
Step-by-step explanation:
Its 1.35 dollars :). hope you get it right
The rule for secants tells you
EC·ED = EB·EA
(x+4)(x+5) = (x+1)(x+12)
9x+20 = 13x+12 . . . . . . simplify, subtract x²
8 = 4x . . . . . . . . . . . . . . add -12-9x
2 = x
The value of x is 2.
