Answer:

C) Reflection about the origin

Step-by-step explanation:

DE points to the right and slightly down. D'E' points to the left and slightly up. The segments are parallel, not perpendicular, so represent a rotation of 180°, not 90°. If the figure were subject only to translation, these segments would point in the same direction.

The transformation is a reflection about the origin (C). (This is equivalent to a rotation of 180°.)

Solve the system by substitution -4.5x-2y=-12.5 3.25x-y=-0.75

gogolik [260]

Answer:

The answer to your question is: x = 1, y = 4

Step-by-step explanation:

I'll change decimals to fractions

4.5 = 9/2

12.5 = 25/2

3.25 = 13/4

0.75 = 3/4

-9/2 x - 2 y = - 25/2 (I)

13/4 x - y = - 3/4 (ll)

Process

from (II) y = 13/4x + 3/4

Sunstitution -9/2x -2(13/4 x + 3/4) = - 25/2

-9/2 x - 13/2 x - 3/2 = -25/2

Multiply by 2 -9 x - 13 x - 3 = -25

-22 x = -25 + 3

-22 x = -22

x = 22/22

x = 1

y = 13/4 (1) + 3/4

y = 16/4

y = 4

Sophia exchanged 1000 U.S. dollars for the South African currency, which is called the rand. The exchange rate was 7.15 rand to

dolphi86 [110]

Part a:-

7.15 rands = 1 dollar

So we are going to MULTIPLY to find out how many rands there are going to be.

1000 × 7.15 = 7150

So, 7150 rands is your answer.

Part b:-

To do this first we will DIVIDE.

6274 ÷ 7.15 ≈ 877.482.......

So, 6274 rands is ABOUT $878.

Par a:- 7150 rands

Part b:- about $878.

Hope I helped ya!!!!!
