r > -11 /multiply by -1
-r < 11

-r < 11 /multiply by 3
-3r < 33

r > -11 /multiply by 3
r > -33

Answer:

Option 1,3 and 4

Step-by-step explanation:

Given : Inequality [tex]r > -11[/tex].

To find : Which of these inequalities are equivalent ?

Solution :

Inequality [tex]r > -11[/tex] ....(1)

Multiply (1) by -1,

[tex]-r < 11[/tex]

So, option 1 is equivalent.

Multiply (1) by 3,

[tex]3r > -33[/tex]

So, option 3 is equivalent.

Multiply (1) by -3,

[tex]-3r<33[/tex]

So, option 4 is equivalent.

Therefore, option 1,3 and 4 are equivalent to given inequality.
