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:
y = -1/2x +2
Step-by-step explanation:
on the y axis, it crosses at 2
find the slope - it goes down I over 2
so the slope -½x and the y-intercept 2
put your equation together giving you y = -½x +2
nope they are not similar
as in order to say that triangles are similar their sides should be in proportion or angles to be equal but here
here only one angle is equal the other one is not
So they are not similar
