What transformation were applied to abc to obtain a’b’c? a-rotate 90degrees counterclockwise, then shift 2 units up b- rótate 90 degrees counterclockwise then shift 2 units down c- rótate 180 degrees counterclockwise, then shift 2 units up d- rótate 180 degrees counterclockwise then shift 2 units down

A )rotate 90 degrees counterclockwise,then shift 2 units up.

Step-by-step explanation:

Given  : graph .

To find : what transformation were applied to ABC to obtain A’B’C.

Solution : We have given graph

Parent ABC triangle with coordinates A(2 ,2) ; B (5 ,6) ; C ( 8 , 2).

Transformed triangle with coordinates  A' (-2 ,4) ; B' (-6 ,7) ; C' ( -2 ,15).

By the rotational of 90° counter clockwise : (x ,y) →→ ( -y , x ).

And it is shifted by 2 unit up

(x ,y) →→ ( -y , x + 2 ).

A(2 ,2) →→ A' (-2 ,4)

B (5 ,6) →→ B' (-6 ,7)

C ( 8 , 2) →→ C' ( -2 ,15).

Therefore, A )rotate 90 degrees counterclockwise,then shift 2 units up.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
