Answer:
A) reflection across the y-axis
Step-by-step explanation:
If 
, then this says that two 
-coordinates are equal for opposite values of 
.
Let 
a point on 
.
Then 
.
We also know that 
and therefore 
is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the -axis.
Example if given both and 
, then 
. This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).

Answer:
La cantidad de dinero adeuda al final de los dos procesos es $1450
Step-by-step explanation:
Los parámetros del proceso son;
La cantidad ahorrada para comprar ropa = $2,000
La cantidad pagada por la ropa = $2600
La cantidad prestada a un amigo = $650
La cantidad adeuda por teléfono celular durante 3 meses = $250
Deje que 'C', represente la suma de las transacciones anteriores, tenemos;
∴ C = 2,000 - 2,600 - 650 - 200 = -1,450
La suma de las transacciones anteriores, C = -$1,450
Por lo tanto, al final de los dos procesos, la cantidad de dinero adeuda es C = $1,450
