Polygon ABCDEF is translated 12 units to the left to create polygon A′B′C′D′E′F′. If DE = 7 units, what is D′E′ ?

gizmo_the_mogwai [7]

A translation is a rigid transformation, which means angle measures and distances from two points do not change.
Polygon ABCDEF is congruent to polygon A'B'C'D'E'F'

DE = D'E' = 7

Answer:

There are 108 inches in 9 feet

Step-by-step explanation:

Well, two unit multipliers mean we have to convert through two units before we arrive at our final answer so we can convert from feet to yards to inches!

We know that 3 feet equal a yard, right?

So we can divide 9 by 3 to get the amount that 9 feet translates to in yards.

$9/3 = 3!$

So we are now done with our first conversion! Our second is going to be from yards to inches!

There are 36 inches in 1 yard so we should multiply 3 by 36 to get the amount in inches!

$3*36 = 108!$

Hi, does anyone know the answer to this question? I’m bad at geometry and I’m struggling to answer it.

Answer:

4th option

Step-by-step explanation:

Given

A (- 5, 13 ) → A' (2, 9 )

- 5 → 2 → + 7 in the x- direction

13 → 9 → - 4 in the y- direction

The translation rule is

(x, y ) → (x + 7, y - 4 ) , then

B (4, - 2 ) → B' (4 + 7, - 2 - 4 ) → B' (11, - 6 )
