Which of these inequalities are equivalent to r > -11? Check all that apply. -r < 11 3r < -33 3r > -33 -3r < 33 -3r > 33

-3r < 33, 3r> -33 and  -r < 11

Step-by-step explanation:

Which of these inequalities are equivalent to r > -11? Check all that apply. -r < 11 3r < -33 3r > -33 -3r < 33 -3r > 33

For the inequality -r < 11

Multiplying both sides by -1 will reverse the sign to have;

-1(-r) > -1(11)

r > -11

for the inequality 3r> -33

Divide bith sides by 3 will not reverse the sign because we are divideing by a positive number

3r/3 > -33/3

r > -11

For the inequality -3r < 33

Divide both sides by -3 will reverse the sign

-3r/-3 > 33/-3

r > -11

Hence the required inequalities are -3r < 33, 3r> -33 and  -r < 11

-3r < 33, 3r> -33 and  -r < 11
