Answer:
r < -5/4
Step-by-step explanation:
r -2r+4 < -9r-6
Combine like terms
-r +4 < -9r-6
Add 9r to each side
-r + 9r+4 < -9r-6+9r
8r+4 < -6
Subtract 4 from each side
8r +4-4 < -6-4
8r < -10
Divide by 8
8r/8 < -10/8
[tex]r = \frac{ - 10}{8} [/tex]
[tex]r - 2r + 4 < - 9r - 6 \\ r - 2r + 9r < - 4 - 6 \\ - r + 9r< - 10 \\ 8r < - 10 \\ r = \frac{ - 10}{8} [/tex]
