Answer 1

Marissa did not change the direction

Answer 2

Marissa did not change the direction of the inequality sign.

Explanation:

Hello!

We can solve the inequality as well, and compare our steps to Marissa's to verify her steps.

Solve the inequality:

• 
  `-\frac x{12} > 7.8`
• 
  `(-12)(x)/(-12) > 7.8( -12)`
• 
  `x < -93.6`
  

We have the same number, but a different inequality sign. This is because we have to flip the inequality sign when multiplying and dividing by a negative number.

Therefore, the answer is the last option, Marissa has to flip the inequality sign when multiplying by a negative number.
