The answer is 2( x - 4 ) = 9
This is basically asking if each transformation is an isometry, which maps a triangle to a congruent triangle.
(x,y)⇒(-y,x) That's an isometry, not scaling x or y. I think it's a 90 degree rotation. CONGRUENT
(x,y)⇒(x-2,y-1/2) No scaling, pure translation. CONGRUENT
(x,y)⇒(2x,2y) That's a double scaling so NOT CONGRUENT
(x,y)⇒(-x,y) That's a reflection. CONGRUENT
(x,y)⇒(1/2 x, 1/2 y) Scaling again, NOT CONGRUENT
Answer: Answer: A dilation factor of 1 over 2

Answer:
376 people
Step-by-step explanation:
25% is 94
to get the there 75% divide 94 by 25% or .25 and you get 376. 25% of that is 94.
