Answer:
-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
