Polygon abcd transformed to create polygon a'b'c'd'. which transformation took place?

horizontal stretch by a factor of 2

translation 2 units to the right

dilation by a factor of 2

vertical stretch by a factor of 2

horizontal stretch by a factor of 1/2

The transformation that took place is:

horizontal stretch by a factor of 2

We are given that Polygon ABCD transformed to create polygon A'B'C'D'.

Clearly the polygon is first a translation of the polygon ABCD 1 units to the right and then it is horizontally stretched by a scale factor of 2.

since, the Length of the polygon was earlier 2 units and then the length of the Polygon A'B'C'D' are 4 units.

Hence, the transformation that took place in the Polygon ABCD is:

a horizontal stretch by a factor of 2

15 videos

Step-by-step explanation:

Let x be the no. of videos rented

Let y represents the total cost.

Discount card from big video costs $9.99 per year

With discount card , Cost of 1 video = $2.49

So, cost of x videos = 2.49 x

So, total cost of videos from Big video = 9.99+2.49 x

Discount card from Main Street Video cost $20.49 per year.

With discount card cost of 1 video = $ 1.79

So, cost of x video = 1.79 x

So, total cost of videos from Main Street Video = 20.49+1.79 x

Now the system of equations are :

  --1

   ---2

Now using substitution method substitute the value of y from 1 in 2

Thus the cost will be same after 15 video rentals .
