Answer:

Step-by-step explanation:
use FOIL
F-firsts

O-outer

I-inner

L-lasts


(2m+3)(m-3)
1. 3/-1x + 4y
2. 3/-2x + 5y
3. 3x+2y
4. 3x+1y
I think :)
The midpoint would be -8 because it is 2 away from both ends.
Answer:
m = 3/5
Step-by-step explanation:
Slope Formula: 
Step 1: Find 2 coordinates
(0, 80)
(-50, 50)
Step 2: Find slope <em>m</em>
m = (50 - 80)/(-50 - 0)
m = -30/-50
m = 3/5
Answer:
Step-by-step explanation:
y+30+2y=180
Add like terms
3y+30=180
Subtract 30 on both sides
3y=150
Divide by 3 on both sides
y=50
Now all you have to do i calculate the angles.
