Answer:
X : red marble
Y: blue marble
X+Y= 81 (•)
Y= 5X+3 (••)
>>> 6X+3= 81 >>>> x=13 and y = 68
BM=CM implies that BCM is isosceles. This means that an altitude from the third vertex A of the triangle ABC, which must necessarily go through M will intersect BC exactly in the middle. This implies that the angles <CBA = <BCA which means the ABC is isosceles.
The answer is 3.6 i know because i am a nerd
U should get the app "photomath" it will help out alot!!!

Answer: Choice A. (-2,1)</h3>
Explanation:
The notation means we apply the dilation to some point (x,y) to move it to . Each coordinate has been multiplied by 4 which is the scale factor. This only works when we center the dilation around the origin. The "O" in refers to "origin". It's not the number zero.
So to go from preimage to image, we multiply by 4. To go in reverse, we divide by 4.
G' is at (-8,4). Divide each coordinate by 4 to get (-2,1) which is where point G is located.
