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:
x = 7
Step-by-step explanation:
(x+2)+(3x-9)+(2x+1) = 36
6x - 6 = 36
6x = 42
x = 7
It means 2 is an element of set V
Imagine negatives as a form of debt, you start out owing someone 3 dollars, (-3); and then you borrow 5 more from them, (-5), add up the total amount of money you owe, which equals (-8). Using a number line, place a dot over where negative 5 is located, before moving back 3 steps to where negative 8 is located. This will give you your problem and answer, (-5)+(-3)=(-8)
