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: x = 4
Step-by-step explanation:
We'll call the number "x."
"Twice the difference of a number and 3" means 2(x-3)
is equal to 2: =2
Put them together:
2(x-3) =2
2x - 6 = 2
2x = 8
x = 4
Check:
2(x-3)
Twice the difference of a number and 3 is equal to 2
2(4 - 3) = 2 ?

Answer:
6.75
Step-by-step explanation:
3/4= 0.75, 6+ 0.75= 6.75
1/4= 0.25, 1/4x3=0.25x3 or 0.25+0.25+0.25= 0.75
