Note that rotation will not affect the shape and size of an object.
Rotation with respect to a point preserves the corresponding sides and the corresponding angles of the original image.
Hence, the statements
The corresponding angle measurements in each triangle between the pre-image and the image are preserved and
The corresponding lengths, from the point of rotation, between the pre-image and the image are preserved
are true.
Answer:
4x1
Step-by-step explanation:
Answer:
210
Step-by-step explanation:
We can write the ratio as ...
bagels : scones = 2 : 3
Then bagels are 2/(2+3) = 2/5 of the total.
# bagels = (2/5)(525)
# bagels = 210
2x-y =3
multiply by 4
8x - 4y = 12
3x +4y = 10 (unchanged equation)
------------------add
11x = 22
answer is A. the first.
first equation multiplied by 4 then sum to get 11x = 22
