-1<=3 ?yes
This is a solution
c: (-3,-1):
I: -3>3 ?no
This is not a solution
d: (1,11):
I: 1>3 ?no
This is not a solution
2) is (8,-1):
I: x+y>=5
II: x-2*y>8
a: (6,1):
I: 6+1>=5
7>=5 ?yes
II: 6-2*1>8
4>8 ?no
This is not a solution
b: (8,-1):
I: 8+-1>=5
7>=5 ?yes
II: 8-2*-1>8
10>8 ?yes
This is a solution
c: (6,2):
I: 6+2>=5
8>=5 ?yes
II: 6-2*2>8
2>8 ?no
This is not a solution
d: (6,-2):
I: 6+-2>=5
4>=5 ?no
This is not a solution
3) is (6,2):
I: 2*x+4*y>0
II: -x+5*y>0
a: (0,0):
I: 2*0+4*0>0
0>0 ?no
This is not a solution
b: (-4,-2):
I: 2*-4+4*-2>0
-16>0 ?no
This is not a solution
c: (6,2):
I: 2*6+4*2>0
20>0 ?yes
II: -6+5*2>0
4>0 ?yes
This is a solution
d: (6,0):
I: 2*6+4*0>0
12>0 ?yes

-6>0 ?no
This is not a solution
94%.
<span>50 x 2 = 100 </span>
<span>47 x 2 = 94 </span>
<span>Percent means per hundred so you need to times 50 by whatever the number is that makes it 100. You need to do this on both sides so you do the same with the 47.</span>
Answer:
x=3, y=1. (3, 1).
Step-by-step explanation:
x+3y=6
2x-7y=-1
------------
x=6-3y
2(6-3y)-7y=-1
12-6y-7y=-1
12-13y=-1
13y=12-(-1)
13y=12+1
13y=13
y=13/13
y=1
x+3(1)=6
x+3=6
x=6-3
x=3
