Answer:
x=0
Step-by-step explanation:
The axis of symmetry: 
when the equation is 
The given equation is:
To make the a and b values more easily identifiable, we can rewrite it like this:
Now, we can tell that a=1 and b=0. Plug these into the equation :
Therefore, the equation for the axis of symmetry for the parabola is x=0.
I hope this helps!
5×2=10 1×10 those two factors equal 10. O cant think of anymore
There are 
ways of drawing a 4-card hand, where
is the so-called binomial coefficient.
There are 13 different card values, of which we want the hand to represent 4 values, so there are 
ways of meeting this requirement.
For each card value, there are 4 choices of suit, of which we only pick 1, so there are 
ways of picking a card of any given value. We draw 4 cards from the deck, so there are 
possible hands in which each card has a different value.
Then there are 
total hands in which all 4 cards have distinct values, and the probability of drawing such a hand is
Lexi borrowed $425 and paid back $450, so the interest paid was $25 (subtract 450 and 425). Then divide the interest over the expression P*t = 425*0.5 = 212.5 to get 25/212.5 = 0.1176 approximately which converts to the annual interest rate of 11.76% (approximately).
If you want to use a formula, then,
i = P*r*t
25 = 425*r*0.5 <---- t = 0.5 to represent half a year
25 = 4250.5*r
25 = 212.5*r
212.5*r = 25
r = 25/212.5
r = 0.1176
r = 11.76%
Answer:
Ac=cd & ab=bd +common side so abc=dbc
same for ehf and ghf but difference in common right angle.
