Answer:
C). Nonrigid transformation.
F). Stretch
Step-by-step explanation:
Transformation in mathematics is defined as the alteration or variation in the shape of an object without altering the lengths by using a flip, turn, slide, or resizing.
The transformation 'Hexagon ABCDEF → hexagon A'B'C'D'E'F'' would best be described as the 'non-rigid' and 'stretch' transformation. Non-rigid because it alters the shape or size of the figure both vertically as well as horizontally. It would be considered a stretch transformation as it is resized by a pull from both the vertical and horizontal angles. Thus, <u>options C and F</u> are the correct answers.

Step-by-step explanation:
Answer:
40,45,95
Step-by-step explanation:
The sum of the angles of a triangle are 180
2x+10 + 3x + 8x-25 = 180
Combine like terms
13x - 15 = 180
Add 15 to each side
13x - 15+15 =180 +15
13x = 195
Divide by 13
13x/13 = 195/13
x =15
The angles are
2x+10 = 2(15)+10 = 30+10 = 40
3x = 3(15) = 45
8x-25 = 8(15) -25 = 120-25 = 95
Answer:
The system of linear equations are
and 
Step-by-step explanation:
Given : The number of students who chose lunch was 5 more than the number of students who chose breakfast. Let x represent the number of students who chose breakfast and y represent the number of students who chose lunch.
(50 students picked, 25 picked dinner the rest picked lunch and breakfast)
To find : Write a system of linear equations that represents the numbers of students who chose breakfast and lunch ?
Solution :
The number of students who chose breakfast be 'x'
The number of students who chose lunch be 'y'.
The number of students who chose lunch was 5 more than the number of students who chose breakfast.
i.e. 
Now, Total student were 50 and 25 picked dinner the rest picked lunch and breakfast i.e. 25.
So, 
Therefore, the system of linear equations are
and
