Triangle EFG is dilated by a scale factor of 3 centered at (0, 1) to create triangle E'F'G'. Which statement is true about the d
lesya [120]

Answer:

segment EH and segment E prime H prime both pass through the center of dilation.  

Step-by-step explanation:

Center of dilation is point (0.1), same as H. Both, E(0,5) and H(0,1) are placed over y-axis, then E' and H' are also located at y-axis.

After dilation, H' is placed at (0,1) because it coincides with the center of dilation

Distance between E and center of dilation is 4 units, then E' should be at 4*3=12 units from the center of dilation and over y-axis. Therefore, E' is placed at (0, 13)

So, segment E'H' goes from (0,1) to (0,13), and pass through the center of dilation, like segment EH.

The domain for variables x and y is the set {1, 2, 3}. The table below gives the values of P(x, y) for every pair of elements fr
Olin [163]

Answer:

Option B and C are correct answers.

Step-by-step explanation:

Option B and C are the correct options.

Option a is true since row 1 has all T.

so for X=1, P(x,y) is true for all y.

Option b is false since no column has all F.

Option C is false since no column has all F.

Option D is true since 1st row has all T.

hence option B and C are correct answers.
