Question

3r+2<5 or 7r-10>60 please help me with this problem I have been stumped for awhile

Answer 1

First we have to simplify

3r + 2 < 5
subtract 2 from each side then divide by 3
r < 1

7r - 10 > 60
add ten to both sides. divide by 7.
r > 10

answer: r<1 or r>10

if you have to graph, you should have a number line going from 0 to 11. You should put an open circle on 1 and an open circle on 10. Shade to the left from the open circle on 1, and then shade from the right from the open circle on 10.

Your union should look like this:
(-♾, 1)U(10,+♾)
