Common ratio = second term/first term = -10/2 = -5
Answer:
Step-by-step explanation:
The vertex for the first one is: (8,-1)
the answer for the second one is: n = -8 + with a - at the bottom square root of 151
the answer for the third question is: n = (-3,-5)

Answer:
(-3 + -2y)(5 + -1y) = 0
Step-by-step explanation:
Simplifying
(y + -5)(2y + 3) = 0
Reorder the terms:
(-5 + y)(2y + 3) = 0
Reorder the terms:
(-5 + y)(3 + 2y) = 0
Multiply (-5 + y) * (3 + 2y)
(-5(3 + 2y) + y(3 + 2y)) = 0
((3 * -5 + 2y * -5) + y(3 + 2y)) = 0
((-15 + -10y) + y(3 + 2y)) = 0
(-15 + -10y + (3 * y + 2y * y)) = 0
(-15 + -10y + (3y + 2y2)) = 0
Combine like terms: -10y + 3y = -7y
(-15 + -7y + 2y2) = 0
Solving
-15 + -7y + 2y2 = 0
Solving for variable 'y'.
Factor a trinomial.
(-3 + -2y)(5 + -1y) = 0
The statement that cannot be true is that g cannot be parallel to h (g ║h)
<h3>How to know parallel lines in a plane?</h3>
On the plane ,
line b is parallel to line f.
Therefore,
b ║ f
line f is parallel to line g,
Therefore,
f ║ g
line h is perpendicular to line b.
h ⊥ b
Therefore,
Since line h is perpendicular b, line b is perpendicular to h.
b can be parallel to g on the plane.
g cannot be parallel to h because h is perpendicular to b.
h can be perpendicular to f because b is parallel to f.
