Answer:
a reflection alomg y axis followed by translation
D
Step-by-step explanation:
The number of guests is the independent variable and should be between 1 and 50. We can use a scale of 10's
The cost is the dependent variable and the minimum cost is 100 and should rise from there
The scale would be from 100 's
Answer: 28
Step-by-step explanation: 3(28)- 21=63
These two triangles are similar and the conversion factor is 2/3. This can be found by dividing one side length corresponding to the other on the other triangle.
In this case, DF ~ AC
DF = 12
AC = 18
12/18 = 2/3
Knowing this, we can multiply 15 by 2/3 to find the length of DE because side lengths AB and DE are similar.
15 • 2/3 = 10
DE = 10
