Matt did an experiment to study the solubility of two substances. He poured 100 mL of water at 20 °C into each of two beakers labeled A and B. He put 50 g of Substance A in the beaker labeled A and 50 g of Substance B in the beaker labeled B. The solution in both beakers was stirred for 1 minute. The amount of substance left undissolved in the beakers was weighed. The experiment was repeated for different temperatures of water and the observations were recorded as shown.
Part 1: Which, if any, substance is soluble in water?
Part 2: Explain how the data helped you determine solubility for both substances for temperatures 20 °C to 80 °C.

Answer:
The dilation scale factor is .
Step-by-step explanation:
The image is the dilated form of its preimage if and only if the following conditions are observed:
1)
2)
3)
4)
5)
If we know that ,
,
,
,
,
,
and
, then the coefficients are, respectively:
,
,
,
As , we conclude that the dilation scale factor applied in the preimage is equal to
.
