Aline segment has an endpoint at (-4,10) and a midpoint at (-8,0). find the other endpoint.

  (-12, -10)

Step-by-step explanation:

Midpoint M is the average of endpoints A and B:

  M = (A +B)/2

  2M = A + B . . . . . . multiply by 2; next, subtract A

  B = 2M - A . . . . . . the missing endpoint can be found this way

  B = 2(-8, 0) -(-4, 10) = (2(-8)+4, 2(0)-10) = (-12, -10)

the monthly balance will be $75,000

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
