Hi there!

Let's solve this inequality step by step!
- 6r + 2r > 3 - 3r

First collect the terms on the left.
- 4r > 3 - 3r

In order to solve, we must isolate r. Therefore we need to bring them all to the left. Our next step will therefore be to add 3r to both sides of the equation.
- r > 3

Finally we need to divide both sides of the equation by -1. Because we divide by a negative, the sign flips.
r <  - 3

Hence, the answer is r < -3.
~ Hope this helps you!

What is the rule of function? (0,0),(1,4),(2,16),(3,36)
lilavasa [31]
When the first number increases by one the second number is added by 4's. So from the first part to the second it added 4 then from the 2nd to the 3rd it skips adding 8 to then just add 12. Then from the 3rd to the 4th it skips adding 16 and adds 20. So the next set of numbers would be (4,64) because it skips adding the 24 and adds the 28.
Hope this helps and is not to confusing :)
