Answer:

Danny did not reverse the symbol.

Hence, the correct answer is: [tex]x<-7[/tex]

Step-by-step explanation:

Given the inequality

[tex]- 8x > 56[/tex]

We know that when we multiply both sides by -1, the 'inequality' gets reverse.

i.e.

[tex]\left(-8x\right)\left(-1\right)<56\left(-1\right)[/tex]

[tex]8x<-56[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}<\frac{-56}{8}[/tex]

[tex]x<-7[/tex]

Therefore, Danny did not reverse the symbol.

Hence, the correct answer is: [tex]x<-7[/tex]
