1. True or False: When point E (2, -5) is rotated 180° about the origin, and becomes Point E’ (-2, 5).
2. Under a dilation, triangle XYZ where X(6, 3), Y(-2, 4), and Z(10, -2) becomes triangle X’Y’Z’ where X’(12, 6), Y’(-4, 8), and Z’(20, -4). What is the scale factor for this dilation?
-2
2
1/2
-1/2
3. Triangle XYZ where X(7, 2), Y(-3, 8), and Z(-4, 6) is dilated with a scale factor of -4. Where is the dilation located?

Step-by-step explanation:

1.

when rotated through 180° (x,y)→(-x,-y)

E(2,-5)→E'(-2,5),True

2.

X(6,3)→X'(12,6)

so dilation is 2.

X'(-28,-8)

Y'(12,-32)

Z'(-80,16)

dilation is around origin.

hope this

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
