(3x + 2x -2) + (4x - 2x + 8) = 7x + 6
(2x + 5) + ( 7x - 10) + (3x - 4) + (4x -6) = 16x - 15
(4 + 2x3) + (5x3 + 2) = 27
(6x2 + 3x - 8) + ( 2x2 - 5x - 9) = 8x2 - 2x - 17
(4x2 - 9x3 + 2x4) + (8x4 - 3) + (5x3 - 7x2) = 19
(3 - 4x3 +6x4) + (2x4 + 5) + (9x3 - 8x2) = 39
(9x + 7y4) + (5x + 3x2 - 7y4) = 3x2 + 14x
<span>(9x2 - 5y - 12) + (8 - 9x2 + 5y + 4) = 0</span>
Answer: They are related by the AAS postulate and they can be proven congruent.
Step-by-step explanation: You can see that one of the lines on each of the triangle has that little tick which means those lines are congruent. You can also see that for two of the angles one of them has one arc and the other has two arcs for BOTH triangles which makes those two angles congruent. Two angles and one side congruent makes the triangles congruent by the AAS postulate.
I hope I helped! :)
Answer:
x=-2, y=-9/2. (-2, -9/2).
Step-by-step explanation:
x=2y+7
3x-2y=3
--------------
3(2y+7)-2y=3
6y+21-2y=3
6y-2y+21=3
4y+21=3
4y=3-21
4y=-18
y=-18/4
simplify
y=-9/2
x=2(-9/2)+7
x=-9+7
x=-2
Answer:
d
Step-by-step explanation:
The speed is the independent variable because when it changes all the others change because it changed
Survey
By conducting a survey, you can ask people who have seen the new movie what they think about it. This will be the best approach to get a straightforward answer from these people.
