I'll call the answer options A, B, C, and D, in that order from top to bottom. The line is a dotted line, so the inequality cannot be a greater/less than or equal to. Thus the answer choices B and D are eliminated. According to the graph, the point (0,0) is one of the possible solutions of the inequality. So, just substitute (0,0) into the inequalities for A and C. For C, you get 0 < -3, which is not true, so C is wrong. For A, you get 0 > -3. This is true, so the correct answer must be A, or y > -2x - 3
Answer:
f 6 n +−6 n +15
Step-by-step explanation:
f 6 n+(−3)(2 n)+(−3)(−5)
f 6 n +−6 n +15
410x400 is correct and your answer would be 164,000.
You need to have a little more detail in your answer, sir or madam.
1)
I:x-y=-7
II:x+y=7
add both equations together to eliminate y:
x-y+(x+y)=-7+7
2x=0
x=0
insert x=0 into II:
0+y=7
y=7
the solution is (0,7)
2)
I: 3x+y=4
II: 2x+y=5
add I+(-1*II) together to eliminate y:
3x+y+(-2x-y)=4+(-5)
x=-1
insert x=-1 into I:
3*-1+y=4
y=7
the solution is (-1,7)
3)
I: 2e-3f=-9
II: e+3f=18
add both equations together to eliminate f:
2e-3f+(e+3f)=-9+18
3e=9
e=3
insert e=3 into I:
2*3-3f=-9
-3f=-9-6
-3f=-15
3f=15
f=5
the solution is (3,5)
4)
I: 3d-e=7
II: d+e=5
add both equations together to eliminate e:
3d-e+(d+e)=7+5
4d=12
d=3
insert d=3 into II:
3+e=5
e=2
the solution is (3,2)
5)
I: 8x+y=14
II: 3x+y=4
add I+(-1*II) together to eliminate y
8x+y+(-3x-y)=14-4
5x=10
x=2
insert x=2 into II:
3*2+y=4
y=4-6
y=-2
the solution is (2,-2)
