Answer:
See proof below
Step-by-step explanation:
We will use properties of inequalities during the proof.
Let
. then we have that
. Hence, it makes sense to define the positive number delta as
(the inequality guarantees that these numbers are positive).
Intuitively, delta is the shortest distance from y to the endpoints of the interval. Now, we claim that
, and if we prove this, we are done. To prove it, let
, then
. First,
then
hence
On the other hand,
then
hence
. Combining the inequalities, we have that
, therefore
as required.

Hello,
Answer is Dsince y=k(x-2)²-5 and if k=1 ==>D.
Answer:
the answer is C
Step-by-step explanation:
<span>Simplifying
17x2 + -12x = 0
Reorder the terms:
-12x + 17x2 = 0
Solving
-12x + 17x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), 'x'.
x(-12 + 17x) = 0
