The coordinates of the vertices of △DEF are D (1, 2) , E (2, 0) , and F (−1, 0) . The coordinates of the vertices of △D′E′F′ are D′(2, 1) , E′(0, 0) , and F′ (0, 3) .

What is the sequence of transformations that maps △DEF to △D′E′F′ ?

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
