Given:
The system of equations is


To find:
The true statement about the given system of equations.
Solution:
The slope intercept form of a line is

Where, m is the slope and b is the y-intercept.
We have,


On comparing these two lines with slope intercept form, we get


Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.
Therefore, the correct option is A.
Answer:
Step-by-step explanation:
hola
Cuando dos numeros tienen el mismo signo la respuesta siempre es positiva. cuando un signo es positivo y e lotro es negativo la respuesta siempre sera negativa. Esta es la regla para multiplicar numeros con signos diferentes. el orden de los signos no importa en multiplicacon siempre va ha ser la misma respuesta.
Answer:
One solution x = 2
Step-by-step explanation:
Given the equation:

Multiply this equation by 2:

Use distributive property:

Combine the like terms:

Thus, this equation has one solution x = 2
8+7=15
300/15=20
8 x 20 =160 Boys
7 x 20 = 140 girls
140 + 160 = 300
Hope this helps!
