Given:
The equation of a quadratic function is:
To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is 
, then the equation of the axis of symmetry is:
...(i)
We have,
Here, 
. So, the equation of axis of symmetry by using (i), is
Therefore, the correct option is C.
Original amount = $234
Discount = 15% of $234 = 0.15 x 234 = $35.10
Sale Price = $234 - $35.10 = $198.90
----------------------------------------------
Answer : Sale Price is $198.90
----------------------------------------------
Answer:
C D H
Step-by-step explanation:
The best way to tackle this problem is to put each answer into the equation and evaluate the equation.
for example
-(-3.9) + 6 >= 10
3.9 + 6 >= 10
9.9 >= 10 .this is not true!
be very careful with the signs and evaluate each answer.
