Question

What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}?

3r ≤ 4r – 6

Answer 1

if r=8
2(8)≤ 3(8)-8
16≤ 16

if r=9
2(9)≤3(9)-8
18≤ 19

if r=10
2(10)≤ 3(10)-8
20≤ 22

Answer 2

So it would be {8, 9, 10}

Answer 3

Thank you. Would {7,8,9,10} also be correct? That is the answer choice closest to yours.

Answer 4

Hmmm, I would assume so.

Answer 5

Ok. Thank you. :)
