The answer is a. b>-2 because 
6b<24 
b< 24/6
b<4
And 
4b+12>4
4b>4-12
4b>-8
b>-8/4
b>-2

Step-by-step explanation:
<u>Equation of the Circle</u>
A circle can be completely defined knowing its center and radius. The radius is the distance from the center to any point in its edge. Since we know the center of the circle is (-10,-7) and one point in its edge is (4,4), we calculate the distance between those points:

Answer:
Option D) -9
Step-by-step explanation:
Here (6 , n) corresponds to an ordered pair solution that is (x , y) so we have the value of x that is 6 but we need the value of y which is f(x) so we insert the value of x into the function to get the value of n like this,

because f(x) corresponds to y and hence f(6) corresponds to n
