Answer:
1. 
and 
are Corresponding Angles
2. 
and 
are Alternate Interior Angles
3. and 
are Alternate Exterior Angles
4. 
and are Consecutive Interior Angles
Step-by-step explanation:
Alternate Interior Angles - When a pair of angles are in the interior in the opposite sides of the transversal.
Alternate Exterior Angles -When a pair of angles are in the outside in opposite sides of the transversal.
Corresponding Angles - When a pair of angles are in the same side of one of two sides by a cross-section.
Consecutive Interior Angles - When a pair of angles on the side are same but inside the two lines.
Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14)
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
Point slope equation:
y-y1=m(x-x1)
m=slope
So we simply plug in our given information:
x1=-8
y1=2
m=1/2
y-2=1/2(x-(-8)
2 minus signs next to each other make a positive
Final answer:
y-2=1/2(x+8)
2(4x-3)-7(x+1) first distribute
8x-6-7x+7 then combine the x's
<u>x+13 </u>
