-1/4 + f/8 = 1/2.
The LCD is 8. Rewrite this equation as -8/4 + 8f/8 = 8(1/2) and then reduce the result:
-2 + f = =4
Then f = 6.
You should check this result.
Notice the picture below
x = 1 and y = -1
now... recall your SOH CAH TOA

now.. what's the value for "r" or the radius? well, using the pythagorean theorem
Answer:
Step-by-step explanation:
6.50$
Answer:
Step-by-step explanation:
(-8+2)/2= -6/2 = -3
(-3+7)/2= 4/2 = 2
(-3, 2) midpoint
Answer:
Step-by-step explanation:
You need to use vertex form of a quadratic to solve this.
Consider the vertex to be 
Another way of representing a quadratic is in "vertex form":

Now all you have to do is solve for a. You know that the vertex is
and you have know the point of
. Now, all you have to do is plug in these values and solve for a.

Now you know the equation is
, but you need it in quadratic form. All you have to do is solve is distribute the 6:

You get:
a = 6
b = 0
c = 2
