4
6

10
O A. A' (0, 10), B'(16,6). C'(8, 2)
O B. A'(0,20), B' (16, 12). C'(8,4)
O C. A'(0,5), B'(4,3), C' (2, 1)
O D. A'(0,20), B' (8, 12), C'(4,4)
SUBMI

Option B

Step-by-step explanation:

Rule for the dilation of point (x, y) by a scale factor 'k' about the origin,

(x, y) → (kx, ky)

By this rule vertices of triangle ABC when dilated by a scale factor of 2 to form ΔA'B'C',

A(0, 10) → A'(0, 20)

B(8, 6) → B'(16, 12)

C(4. 2) → C'(8, 4)

Therefore, Option B will be the correct option.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
