HELP PLEASE Rectangle A′B′C′D′ is the image of rectangle ABCD after a dilation.

What is the scale factor of the dilation?

A coordinate plane that includes two rectangles rectangle ABCD and rectangle A prime B prime C prime D prime. For rectangle ABCD, point A is at (1, 5), point B is at (4, 5), point C is at (4, 1), and point D is at (1, 1). For rectangle A prime B prime C prime D prime, point A prime is at (3, 15), point B prime is at (12, 15), point C prime is at (12, 3), and point D prime is at (3, 3).

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

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

i recommend you do what your heart desires. if you're attracted to the same gender, then you're attracted to the same gender. you can't determine what your heart wants.
