Answer:
7
Explanation:
From the question, we're told that triangles AMY and MEG are similar. If triangle AMY has sides AM = 5, MY = 7, and AY = 3 then we can find the side lengths of triangle MEG since we're told from the question that it is a dilation of AMY by a scale factor of 1/3.
So all we need to is multiply the corresponding sides of AMY by 1/3, so we'll have;

We can then go ahead and find the perimeter of MEG. Note that to find the perimeter of a triangle, we add all the length of its sides;

The perimeter of MEG is 7.

Answer:
Top left one on the attached, must be option A
Step-by-step explanation:
A function has to have unique input values and for each input value has to have an output value.
Analyzing the graphs we can see that only one of them is a function- top left one
All the others have repeat input values, therefore are not functions
All those points marked with red circle

Answer:
-45 < x < 5 (see graph below)
Step-by-step explanation:
to isolate x by itself, subtract 20 from all three terms of the equation:

once you finish subtracting 20, x should be by itself, making the equation graphable:

since x is not equal to -45 or 25, the graph line endings have open circles.
Answer:

Step-by-step explanation:
A diagonal is defined in geometry as a line connecting to two non adjacent vertices.
Therefore, the minimum number of sides a polygon must have in order to have a diagonal n - 3 sides as the 3 comes from the originating vertex and the other two adjacent vertices
Given that the polygon has n sides, the number of diagonals that can be drawn from each of those n sides gives the total number of diagonals as follows;
Total possible diagonals = n × (n - 3)
However, half of the diagonals drawn within the polygon are the same diagonals drawn in reverse. Therefore, the total number of distinct diagonals that can be drawn in a polygon is given as follows;
