What inequality represents the verbal expression?

1. all real numbers x less than or equal to − 7 negative 7

   all real numbers  x begin box , all real numbers . x , end box	less than or equal to begin box , less than or equal to , end box	− 7 begin box , negative 7 , end box
   x begin box , x , end box	≤ begin box , less than or equal to , end box	− 7 begin box , negative 7 , end box
