Answer:
The relationship between the lengths of the line segments doesn't change. In all the cases, AB = CD and AC = BD.
Step-by-step explanation:
this is the exact answer word for word, so id recommend to put it in your own words
ex. when i move one point the other points move so the lengths stay equal to each other
B) Find the mean and variance of the number that survive
explanation:
One way to determine the scale factor of a dilation is if you are using a graph then you can pick two corresponding points of the before and after and divide them and you can get the scale factor.
The second one is true because if you have 2 angle measures then you can automatically find the third because we know that all the angles of a triangle add up to 180 so lets say that one angle is 94 degrees and another is 38 degrees we would add those two up to get 132 and then we would subtract that from 180 to get the third angle which would be 48 degrees.
The third one, vertical angles have a common vertex, but they are never adjacent angles. Also, vertical angles are always congruent.
9x^2(2x^2 + 3x -4) / 9x^2
= 2x^2 + 3x -4
The answer is A. Hope this helps!
C; A and B are incorrect because the shift is not vertical, it is horizontal. This is because 3 is in parenthesis or a 'grouping' (same thing if it is in an exponent) and is being modified. Since the graph is being translated down 3 units, D is incorrect since it is a translation up 3 units. The answer is C.
