Type the equations to a website called maths papa-using their algebra calculator, i highly recommend it, it shows all the working clearly and the answers are always correct
Mel's Age = xRahfat's Age = x-3Aurelio's Age = 2x 2x + x +x -3 = 574x -3 = 574x = 60x = 15So Mel's age is 15.Hope this helps! :D
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).
