Answer:
see explanation
Step-by-step explanation:
Given
y = x² - 2x - 8
To find the x- intercepts let y = 0 , that is
x² - 2x - 8 = 0 ← in standard form
(x - 4)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
x- intercepts : x = - 2, x = 4
The x- coordinate of the vertex is mid way between the x- intercepts, that is
= 
= 
= 1
Substitute x = 1 into the equation for corresponding y- coordinate
y = 1² - 2(1) - 8 = 1 - 2 - 8 = - 9
vertex = (1, - 9 )
Answer:
Total without the discount $52.50. Total with the discount $52.
Step-by-step explanation:
First, start by adding the 2 dollar discount to the total. Next remove the ten dollars for the Frequent Gamer card. This brings the total of the games to $210. Now all you have to do is divide by 4 and you have your answer. To get the answer with the discount skip the first step.

Answer:
42cm squared
Step-by-step explanation:
You are taking 2 x 0.5cm of the smaller sides rectangles which is 1. Then what is left is 6x7 which is 42cm squared
Answer:
Option D) is correct
That is Option D) "The diagonals bisect each other" is correct
Step-by-step explanation:
The property of all squares is
"The diagonals of a square bisect its angles" and it can be written also also as below
"The diagonals bisect each other"
Therefore Option D) is correct
That is Option D) "The diagonals bisect each other" is correct
