On call = 3.5 hours for 10 dollars => ½ hour for 1.25 dollars. Now, let’s solve the unit rate for each company first = 3.5 hour / 10 dollars => 10 / 3.5 => Unit rate is 2.9 dollars/hr Second company = ½ hour for 1.25 dollars => 1.25 / .5 => 0.25 dollars / hr. Thus, the first company pays better than the second one because it pays 2.9 dollars every hour of talk compare to the 2nd one which pays only 0.25 dollars per hr.

After 180 degree rotation, C will be located at (3, -6)
Do u want the first or second derivative
df/dx= 10-2y, df/dy= -2y+14,
then second deriv is df/dxdy=-2
df/dydx=0
The given equation is 
We need to solve the equation for q.
<u>Value of q:</u>
Let us determine the value of q from the equation
Subtracting both sides of the equation by r, we get;
Now, dividing both sides of the equation by b, we have;
Simplifying the terms, we get;
Therefore, the value of q is 
Hence, Option B is the correct answer.
