Answer:
1st answer
Step-by-step explanation:
Answer: A. Figure ABCD is similar to figure A'B'C'D'.
Step-by-step explanation:
Given : Figure ABCD is reflected about the x-axis to obtain figure A'B'C'D'.
Since a reflection is a rigid transformation which produces congruent images.
⇒ Figure ABCD must be congruent to figure A'B'C'D'.
⇒ Figure ABCD has same size as figure A'B'C'D'.
⇒ Figure ABCD must be similar to figure A'B'C'D'. [ ∵ If two figures are congruent then they are also similar.]
Reflection preserves side length and measure of angles .
⇒ Corresponding angles and side lengths of figure ABCD must be congruent to figure A'B'C'D'.
⇒ The measure of angle D is equal to the measure of angle D'.
Hence, the statement best describes the relationship between the two figures is :-
A. Figure ABCD is similar to figure A'B'C'D'.
The correct answer is C. (1, -3).
In the brackets, the first number
refers to x, and the second to y (like when you write coordinates).
So
we can check what is y ineach of the options and compare whether both of the sided of the equasion are equal:
A. 2x-5=-1, should be 11, false
B.
2x-5=4-9=-5, should be 1, false
C. 2x-5=2-5=-3, should be -3, correct
D.
2x-5=10-5=5, should be -5, false
Answer:
x > 5
Step-by-step explanation:
x-8>-3
Add 8 to each side
x-8+8>-3+8
x > 5
