Answer


Option C ,D and E



Step-by-step explanation



Any time we divide an inequality by a negative number, we reverse the sign



The first error is that,


She did not change the sign > to <



Another mistake is that, she divided one side by -5 and multiplied the second by -5



Also whenever an inequality involve < or > we use an open circle on the number line.



So another mistake is that,



She used a closed circle instead of an open circle on the number line




The correct thing should have been




-5x-3.5\:>\:6.5





-5x\:>\:10






x\:<\:-2




The number line is shown in the attachment.
