Triangle abc is rotated to create the image a'b'c'.

on a coordinate plane, 2 triangles are shown. the first triangle has points a (negative 1, negative 1), b (1, negative 1), and c (0, negative 4). the second triangle has points a prime (1, 1), b prime (negative 1, 1), and c prime (0, 4).
which rule describes the transformation?

(x, y) → (x, –y)
(x, y) → (y, x)
(x, y) → (–x, –y)
(x, y) → (–y, –x)

The transformation used here is,

(x, y) → (-x , -y)

Step-by-step explanation:

Triangle ABC is rotated to create the image of triangle A'B'C'

Co-ordinates of A, B, C are,

A = (-1 , -1) ; B = (1 , -1) ; C = (0, -4)

Co-ordinates of A' ,B' , C' are,

A'= (1 , 1) ; B' = (-1 , 1) ; C' = (0, 4)

Hence, the transformation used here is,

(x, y) → (-x , -y)

(x, y) → (–x, –y)

Step-by-step explanation:

Coordinates of triangle ABC:

A (-1, -1)

B (1, -1)

C (0, -4)

If we apply the transformation (x, y) → (–x, –y) we will get:

A (-1, -1) → (1, 1)   which correspond to point A'

B (1, -1) → (-1, 1)   which correspond to point B'

C (0, -4) → (0, 4)   which correspond to point C'

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
