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 :)
Answer:
D) 4 E) 15 F) 30 G) 30 H) 70
Step-by-step explanation:
D) the square root of 4 is 2. We do 2 x 2 = 4.
E) the square root of 9 is 3. We do 3 x 5 = 15.
F) the square root of 25 is 5. We do 5 x 6 = 30.
G) the square root of 36 is 6. We do 6 x 5 = 30.
H) the square root of 100 is 10. We do 10 x 7 = 70.
