Step 1: Simplify both sides of the equation.
17−2n=9
17+−2n=9
−2n+17=9
Step 2: Subtract 17 from both sides.
−2n+17−17=9−17
−2n=−8
Step 3: Divide both sides by -2.
−2n−2=−8−2
n=4
Answer:
Step-by-step explanation:
If we drew an auxiliary line parallel to line 
and line 
that intersects the vertex of 
, we would form three angles, one of them being
The largest of these angles corresponds with the angle marked as 
.
The angle on the bottom right corresponds with the angle next to the one marked as 
. Therefore, its measure is 
.
Since there are 
in a circle, we can now write the following equation:
.
Actually I don't know the answer but what I thing is none of the above.
Answer:
Option C.
Step-by-step explanation:
This is a function because all of the numbers have a partner, and none of them have more than one.
