Q:
# Which types of dilation are the given scale factors?Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.Scale Factor Expansion Contraction−4 2.5 2/3 −3/4

Accepted Solution

A:

Answer:−4 is an expansion; 2.5 is an expansion; 2/3 is a contraction; and −3/4 is a contraction.Step-by-step explanation:In a dilation, a scale factor greater than 1 or less than -1 is an expansion. It will make the figure larger. This means that -4 is an expansion, since it is less than -1, and 2.5 is an expansion, since it is greater than 1.A scale factor that is greater than -1 but less than 1 will be a contraction. It will make the figure smaller. This means that 2/3 is an expansion, since it is less than 1, and -3/4 is a contraction, since it is greater than -1.
