Hope this helps you
The x values stay the same but the y values change to their opposites.
For example: (2,4) reflected across the x-axis would be (2, -4)
and (6, -3) reflected across the x-axis would be (6, 3)
I hope you understand my explanation.

Answer: 2/3, -4/3</h3>
=========================================================
Explanation:
You could use the AC method to factor this, but the quadratic formula is the most efficient route in my opinion. This will avoid any guess-and-check.
Compare the original equation to the form 
We have a = 9, b = 6, and c = -8
Those values lead to...
Side notes:
- 2/3 = 0.667 approximately
- -4/3 = 1.333 approximately
- Since your teacher did not give rounding instructions, I'll assume s/he wants the fraction form of each x value (rather than the decimal form). Be sure to follow all instructions given, and ask for clarification if need.
- To confirm the solutions, replace every copy of x with either 2/3 or -4/3 (pick one value only). Simplifying the left hand side should lead to 0. I'll let you check each answer.
Pregunta completa:
En un parque hay una tienda donde se alquilan patines a 0,50 € la hora; Patinetas a 1 € la hora y bicicletas a 2 € la hora. ¿Cuál es la ecuación de los costos en función del tiempo empleado en cada uno de los casos?
Respuesta:
C (t) = 0,50 billones de euros; C (t) = € t; C (t) = 2 billones de euros
Explicación paso a paso:
Dada la siguiente tarifa de alquiler:
Patines = 0,50 € por hora
Patinetas = 1 € por hora
Bicicletas = 2 € la hora
La ecuación de costo en función del tiempo en cada caso se puede expresar como:
Costo en función del tiempo; Connecticut)
Donde, t = tiempo
Costo, C (t) = costo por hora * Número de horas
C (t) para patines:
C (t) = 0,50 t €
Costo ; C (t) para patinetas:
C (t) = € t
Costo ; C (t) para bicicletas;
C (t) = 2 billones de euros
