Answer:
CF
Step-by-step explanation:
we know that
An <u><em>angle bisector</em></u> is a line that divide an angle into two equal angles.
In this problem
---> given problem
---> by addition angle postulate
so
CF is an angle bisector of angle 
The length of the line is 21.
Answer: Option D
Step-by-step explanation:
The equation of a line in the form of "slope-interception" has the following form:

Where m is the slope of the line and b is the interception of the line with the y axis.
In this case we know that the line has a slope of -2. Then
.
We also know that the line intercepts the axis y at the point (0, 3) therefore we know that:
.
Finally the equation of the line will be:
If we add 2x on both sides of the equation we get:
The answer is the option D
Answer:
f(g(2)) = 44
Step-by-step explanation:
g(2) = 3(2) + 1 = 7
Plug 7 into f(x) since g(2) = 7
f(7) = 7² - 5 = 44
f(g(2)) = 44
