HELP!!! 10 POINTS OFFERED!!THIS IS MY LAST QUESTION!!

Sladkaya [172]

Answer:

A (-2,8) B (-1,5) C (-6,2)

A(-2,-7) B(-5,-8) C(-8,-3)

Step-by-step explanation:

x,y x,y x,y

A(7,-2) , B(8,-5) , C(3,-8)

translation (7-9),(-2+10) (8-9),(-5+10) ( 3-9),(-8+10)

(x-9) and (y+10) (-2,8) (-1,5) (-6,2)

when rotation 270 degrees counterclockwise around the origin:

A(x,y ) Then A'(-y,x) means switch x and y and make x negative

A(7,-2 ) rotation 270 degrees counterclockwise (-2,-7)

B(8,-5) to (-5,-8)

C(3,-8) to (-8,-3)

Sergeeva-Olga [200]

X^3 +3x^2 +5x +3 / x+1 = x^2 +2x +3
x^3 +x^2
------------
0 2x^2 +5x
2x^2 +2x
----------------
0 3x +3
3x +3
---------
