Answer 1

Answer

Option C ,D and E

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

$-5x-3.5\:>\:6.5$

$-5x\:>\:10$

$x\:$

The number line is shown in the attachment.
