What is the solution set for the given inequality if the replacement set for r is {5, 6, 7, 8, 9, 10}? 2r ≤ 3r – 8

OpenStudy (calculusxy):

The sign that is in between of 2r and 3r means that 2r is less than or equal to 3r-8. You want to find a set of numbers that can actually replace the variable of r into both the coefficients of 2r and 3r.

OpenStudy (anonymous):

ok

OpenStudy (calculusxy):

Now you think of what numbers can be replaced for r?

OpenStudy (anonymous):

5 and 6?

OpenStudy (anonymous):

8 9 and 10

OpenStudy (anonymous):

am i correct

OpenStudy (calculusxy):

Well r is only one variable meaning that it there is only one number. To find it out try to substitute and use for all the possibilities.

OpenStudy (anonymous):
