No options ??? hopefully im correct i believe its 5x+8 tell me if i was wrong
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 :)
K = 6
plug in 6 for k
44(6 - 6)
Follow PEMDAS
6 - 6 = 0
44(0) = 0
your answer is 0
hope this helps
Radical 7
radical 84=2 radical 21
radical 21 divided by 2 radical 3 is radical 7
