Answer:
C
Step-by-step explanation:
Answer:
C (x, y) -> (x + 7, y + 8); scale factor = 3
Step-by-step explanation:
The translation can be found by subtracting the coordinates of the original center from those of the center of the image. The scale factor will be the ratio of the radii.
__
<h3>translation</h3>
We note the center coordinates are I(-3, -6) and I'(4, 2). Then the translation is ...
I' -I = (4, 2) -(-3, -6) = (4 +3, 2 +6) = (7, 8)
(x, y) ⇒ (x +7, y +8)
<h3>scale factor</h3>
The radius of each circle can be found by counting the grid squares from the center to the circle. It works best to do this along a horizontal or vertical line.
The radius of circle I is 2; the radius of circle I' is 6. The scale factor is ...
scale factor = 6/2 = 3
Answer:
A
Step-by-step explanation:
1. A horizontal number line is shown with labels at negative 50, 0, and 35. A red arrow (labeled withdrew 50 dollars) begins at 0 and ends at negative 50. A blue arrow (labeled deposited 35 dollars) begins at 0 and ends at 35.
2. A horizontal number line is shown with labels at negative 50 and 0. A red arrow (labeled withdrew 50 dollars) begins at 0 and ends at negative 50. A blue arrow (labeled deposited 35 dollars) begins at negative 50 and ends at negative 15.
3. A horizontal number line is shown with labels at negative 35, 0, and 50. A blue arrow (labeled deposited 35 dollars) begins at negative 35 and ends at 0 A red arrow (labeled withdrew 50 dollars) begins at 50 and ends at 0.
4. A horizontal number line is shown with a label at 0. A blue arrow (labeled deposited 35 dollars) begins at 0 and ends at 35. A red arrow (labeled withdrew 50 dollars) begins at 35 and ends at negative 15.
