Very solve the inequality 6r + 30 ≥ 12 or -r > 12 (the question is important for high school application c: ) a) {r > -12} -- b) {r < -12 or r ≥ -3} -- c) {-12 < r < -3} -- d) {r > -3}

First simplify the one inequality, 6r + 30 greater than or equal to 12 just divide by 6 then subtract 30 from both sides of the inequality. You should get r is greater than or equal to -3. For this one you need to reverse the inequality symbol then divide both sides by -1 to get a positive r, and you get r is less than -12. It's not A because there's two solutions, and it's not D for the same reason. It's not C because r isn't greater than -12. In conclusion it's B because it correctly represents the solutions that make the inequality true. I hope this helps you on your high school application :)
