Answer:
A, B
Step-by-step explanation:
The flag has 180° rotational symmetry, so rotation by that amount around the center will map either triangle to the other.
The legs of the triangles are different lengths, so no rotation of 90° or 270° can map one to the other.
The two choices shown below are applicable.
3x-12y = 5
-x+3y = 9
First step is to make the coefficient of either x or y same.
3x-12y = 5
(-x+3y = 9)3
3x-12y = 5
-3x+9y = 27
-4y = 32
y = -8
Answer:
10 i think it is yea. so 10 is it
Answer:
q + 10 - r
Step-by-step explanation:
add q and 10 = q + 10
then subtract r from the result = q + 10 - r
