Its will be 50 pairs
starting with 0+99=99 1+98=99
2+97=99 and so on
Answer:
D.(2,-1,-1)
Step-by-step explanation:
-a+4b+2c=-8
3a+b-4c=9
b = -1
Substitute b=-1 into the other equations
-a -4 +2c = -8
3a -1 -4c =9
Multiply the first equation by 2 so we can eliminate c
-2a -8 +4c = -16
Add this to the second equation
-2a -8 +4c = -16
3a -1 -4c =9
-----------------
a -9 = -7
Add 9 to each side
a-9+9 = -7+9
a =2
b=-1
Now we need to find c
-a +4b +2c = -8
-2 -4 +2c = -8
-6+2c = -8
Add 6 to each side
-6+6 +2c = -8+6
2c = -2
Divide by 2
2c/2 = -2/2
c=-1
(2,-1,-1)
All you have to do is find the relationships between the top and bottom and then find how they all r in common
24. adjacent
25. vertical
26. linear
27. vertical
28. linear
29. adjacent
30. adjacent
If the ordered pair is a solution, then the two equations in the system should be true after we plug in the points, like so:
(3) + 3(1) = 6 and 4(3) - 5(1) = 7
Then you simplify. 3 + 3 = 6 and 12 - 5 = 7, therefore the ordered pair is a solution of the given system.
