When dilation is about the origin, as it is here in every case, the image point coordinates are the original (pre-image) coordinates multiplied by the scale factor.
1. Multiply every coordinate value by 5:
... W' = (-5, 10), X' = (-15, -5), Y' = (25, -5), Z' = (15, 10)
2. Multiply every coordinate value by 1/3:
... A' = (-2, 5), B' = (0, 5/3), C' = (1, 10/3)
3. A' = (2, 8), B' = (6, 2), C' = (2, 2)
4. The image coordinates are 5 times the original coordinates, so ...
... the scale factor of the dilation is 5.
Answer:
you should know this
Step-by-step explanation:
hello
35.45
rounded to nearest tenth = 35.5
rounded to nearest whole number = 35
rounded to nearest tens = 40
closest to actual weight = 35.5
Given that large box that contain 11 small boxes costs $2.75. The price, d, f small box will be given by:
d=(Cost of large box)/(Number of small boxes)
Cost of large box=$2.75
Number of small boxes=11
hence
d=2.75/11
Hence the answer is d=2.75/11
this could be simplified further to obtain:
d=0.25
