Answer:
6x^2-3x
Step-by-step explanation:

Hope this helps!
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
7x^2 + -x + -2 + 6x^2 + - 3
6x^3 + 7x^2 – x – 5
Your answer is A: 6x^3 + 7x^2 – x – 5
Answer:
B
Step-by-step explanation:
It’s b because tempo is a steady beat to anything but only if consistent
