Answer:
where
denote arc lengths of two circles
Step-by-step explanation:
Let
denote arc lengths of two circles,
denote corresponding radii and
denote the corresponding central angles.
So,
and 
This implies
and 
As each circle has an arc where the measures of the corresponding central angles are the same, 

As radius of one circle is twice the radius of the other circle,


Slope of the line =
.
y-intercept of the line = -7.
Solution:
General form of equation of a line:
y = mx + c
where m is the slope and c is the y-intercept of the line.
Equation of a line:

To compare this with general equation.


Slope of the line =
.
y-intercept of the line = -7.
Answer:
Because i have no more information i assume you would like it to be solved.
x < -1 or -1/3 < x < 1
Answer:
If there are any rational roots, it would be a factor of your constant term (9) divided by a factor of the high-order coefficient (12).
