Quadrilateral ABC D is the result of dilating quadrilateral ABC D about the point D buy a scale factor of 2/3 Please help i’m dumb

Answers

The diagram is shown below what happens when you dilate with a scale factor 2/3, and the center of dilation is D.

Line A'B' has the same slope of AB, so the lines are parallel.

Line AD and line A'D' are the same line, since D = D'. Recall that the center of dilation does not move when applying a dilation. Point A moves to A', which is one line AD. Due to D being at the center, all lines from the center will connect the four points shown.

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
