given f(x) in factored form, equate to zero for x-intercepts
(x - 8)(x - 4) = 0, hence
x = 4, x = 8 ← x- intercepts
The vertex lies on the axis of symmetry which is situated at the midpoint of the x- intercepts
x- coordinate of vertex = 
= 6
f(6) = (6 - 8 )(6 - 4 ) = -2 × 2 = - 4 ← y-coordinate
vertex = (6, - 4 ) → B
Answer:
One triangle can be constructed.
Step-by-step explanation:
Recap that all the interior angles in a triangle add up to 180. With the given measurements of the angles, 70 plus 80 plus 30 equals 180. Each triangle has the sum of 180 degrees. Therefore, there can only be one triangle that can be constructed. I think you were suppose to put can, not can't. Hope this helps!
Answer:
x=4
Step-by-step explanation:
you subtract the x on both sides
6=2x-2
then you add 2 on both sides
8=2x
then divide 2 on both sides
and you get x=4
Answer: 11 is rational
Step-by-step explanation: All rational numbers are whole numbers.
11 is a whole number.
Irrational numbers cannot be expressed as fractions.
