2x+1 cual es su respuesta ??

??

Step-by-step explanation:

¿A qué es igual la ecuación? x no se puede resolver sin un signo igual al final. por favor responda para que pueda ayudar! :D

x= -1/2

Step-by-step explanation:

2x+1=0

-1 -1

2x= -1

➗ por 2

x= -1/2

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
