I hope this helps you
1=3
2=4
1+4=180 degree
1+2=180 degree
2+3=180 degree
3+4=180 degree
7x+7=112
7x=105
x=15
1+4=180
1+112=180

Answer:

Step-by-step explanation:
-4(8+y)=9
Distribute:
-32-4y=9
Add 32 on both sides:
-4y=41
Divide -4 with 41:
y=-41/4
I think it's the first three.
-7.5 < -7
-4 < -3
-0.5 < -1
(those are the inequalities after i put each of the values for x in the original equation)
