Answer:
The correct option is C) 0.25.
Step-by-step explanation:
Consider the provided numbers.
We need to find the difference using the number line.
Open the parentheses:
This indicate that the arrow will starts from -0.25 and move 0.5 units to right. Arrow will move right because 0.5 is a positive number.
The difference using the number line is shown in figure 1.
Hence the correct option is C) 0.25.
Answer: 1/3
Step-by-step explanation:
We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.
From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)
Then and
Therefore, the scale factor of the dilation is 1/3.
