Give the properties for the equation -2x 2 - y + 10x - 7 = 0. >Vertex

(5/2, 11/2)
(-5/2, 11/2)
(5, -7)

Given:

The quadratic equation is

To find:

The vertex of the given quadratic equation.

Solution:

If a quadratic function is , then

We have,

It can be written as

          ...(i)

Here, .

Putting in (i), we get

On further simplification, we get

So, the vertex of the given quadratic equation is .

Therefore, the correct option is A.

were is the equation

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
