Answer:
Step-by-step explanation:
-2x + 5y = -15
5x + 2y = -6
-10x + 25y = -75
10x + 10y = -30
35y = -105
y = -3
5x + 2(-3) = -6
5x - 6 = -6
5x = 0
x = 0
(0, -3)

Answers: 11-20
Step-by-step explanation: Step 1. Flip the equation Step 2. Add the number to both sides Step 3. Divide both sides by the number to get your answer.
1. v=10 2. m=7 3. r=-9 4. k=9 5. r=0 6. x=10 7. x=6 8. 9=3 9. m=-10 10. n=-10
11.p=0
12.x=10
13.b=4
14.n=0
15.p=2
16.x=8
17.m=8
18.x=3
19.n=-1
20.n=9
Answer:
x=144
Step-by-step explanation:
Use the polygon formula (n-2) * 180 where n is the number of points
This polygon has 8 points
(8-2)*180 = 6 * 180 = 1080
136+124+141+158+116+129+132+x=1080
x=144
