Which representation of a transformation on a coordinate grid does not preserve congruence? A (x, y) → (x,-Y) B (x, y) + (x + 7, y + 7) 1 C (x, y) → (5x7Y) , x D (x, y) → (y, -x)

(x,y) --> (1/7x, 1/7y)

Step-by-step explanation:

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
