Without an equality sign it can not be considered to be an equation and the - or + value of 9x has not been given

What is an angle whose vertex lies on the circle and whose sides are chords of the circle?
Inscribed angle
What do you call the angle whose vertex on the circle and whose sides contain chords of the circle?
It is an inscribed angle.
What is the name of an angle whose vertex is the center of the circle?
A central angle.
Which best describes a parabola?
Given a straight line (a directrix) and a point (the focus) which is not on that line, a parabola is locus of all points whose distance form the directrix is the same as its distance from the focus.
An angle whose vertex is at the center of a circle is a central angle of that circle?
true
What is the standard equation of a parabola that opens up or down and whose vertex is at the origin?
focus , directrix
A parabola that opens upward?
Is a parabola whose directrix is below its vertex.
What equation describes a parabola that opens up or down and whose vertex at the point (hv)?
This is called the 'standard form' for the equation of a parabola:y =a (x-h)2+vDepending on whether the constant a is positive or negative, the parabola will open up or down.
An equation of a parabola that has x equals 2 as its axis of symmetry is?
How about y = (x - 2)2 = x2 - 4x + 4 ? That is the equation of a parabola whose axis of symmetry is the vertical line, x = 2. Its vertex is located at the point (2, 0).
What the Vertex form of a quadratic equations?
The vertex form of a quatdratic equation (otherwise called the graphing form) is y=a(x-h)2+k For those of you who don't know what 'h', 'a', and 'k' are, they are parameters. The negative sign in front of the 'h' refers to the opposite of the x coordinate in the vertex. The 'k' refers to the y coordinate in the vertex. 'A' refers to the stretch or compression factor. So, for example, say you have a parabola with a stretch factor of 2 whose vertex coordinates are (-3,4). The equation would be y=2(x+3)2+4 Of course, if a parabola has no stretch/compression factor, there would be no 'a' in the equation. I hope this helped, and good luck!
What is the line of symmetry for the parabola whose equation is y -x2 x 3?
Did you mean a parabola with equation y=3x^2? The line of symmetry is x=0 or the y-axis.
What are the coordinates of the minimum point of a porabola whose equation is y equals x squared plus three?
y = x2 + 3 Since the x term is missing, the x-coordinate of the vertex is 0. If x = 0, then y = 3. Thus, (0, 3) is the vertex, the minimum point of the parabola.
What is the vertex of a parabola whose equation is y equals x 32?
The given equation is not that of a parabola since there are no powers of 2. Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
What is the line of symmetry for the parabola whose equation is y x2 -x- 3?
-1
What is the line of symmetry for the parabola whose equation is y equals x2 - 12x plus 7?
At: x = 6
What is the line of symmetry for the parabola whose equation is y x2 - 12x 7?
y=x2-12x+7
What is the line of symmetry for the parabola whose equation is y equals x2 plus 10x plus 25?
When x = -5
