4x + 3y = 54 (1)
3x + 9y = 108 (2)
Multiply (1) by (-3)
-12x - 9y = -162
3x + 9y = 108
---------------------add
-9x = -54
x = 6
plug x = 6 into (1) to find y
4(6) + 3y = 54
24 + 3y = 54
3y = 30
y = 10
Answer
(6 , 10)

Given:
The point is (-12,-8).
Rule of transformation is
.
To find:
The coordinates of image after transformation.
Solution:
According to the rule of transformation
, first the point is dilated by factor
with origin as center of dilation after that it was rotated 270 degrees anticlockwise.
If a point is dilated by factor
with origin as center of dilation, then
If a point is rotated 270 degrees anticlockwise, then



Therefore, the coordinates of image after transformation are (-2,3).
