Answer:
87, I'm pretty sure it's just 95-8. I might be wrong.
Answer: 
Step-by-step explanation:
The point-slope form of the equation of the line is:

Where "m" is the slope of the line and
is a point of the line.
You know the value of the slope and you also know a point of the line, then you need to substitute values into
.
Therefore, you get that the equation of this line in point-slope form is:

Answer:
44
Step-by-step explanation:
Given:

Required:
Average range of change from 3 to 9
SOLUTION:
Step 1:
Find f(3) and f(9):
To find f(3), replace x with 3 in the given function




To find f(9), replace x with 9 in the given function




Average rate of change = 
Where,


Plug in the values into the formula for average rate of change.



Average rate of change = 44
Answer:
<DEB= 125 degrees
Step-by-step explanation:
To get this, you would need to know all 2 angles of the triangle.
To find the first angle, simply do 180-107 to get 73(because supplementary angles add up to 180 degrees).
Next, 180-52(given angle)-73 to get 55 because the 3 angles of a triangle add up to 180(triangle angle sum theory).
You would see that <DEB is part of another supplementary angle so, do 180-55 to get 125.
<DEB=125 degrees.
