Point B is located at point (4, -2)
Yea but it would be an obtuse triangle
(2x-1)×4=8x-4
I hope it helps ;)
X + 2 < -4
x < -4 -2
•x < -6
Answer:
B
Step-by-step explanation:
The vertex is the turning point of the parabola.
First find the zeros by equating y to zero, that is
(x - 6)(x + 12) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 12 = 0 ⇒ x = - 12
The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, thus
= = = - 3
Thus the x- coordinate of the vertex is x = - 3 → B
