An image point of a tranformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(6, -12) what was the trans
formation and scale factor? a. reflection with scale factor 3
b. reflection with scale factor 1/3
c. dilation with scale factor 3
d. dilation with scale factor 1/3
Dilation with a scale factor 1/3. the original points are three times as big as the transformed points, so the transformation needed to reduce the size by three times smaller.
234 = a + s s = students a = adults 2a = s after you get the equations you solve. plug 2a into the above equation. so u get 234 = a + 2a 234=3a then divide 3 from each side 78 = a so 78 adult tickets were sold
