Answer:
Explanation:
I know im late but the answer is
c r ≥ −21.75
-2.5r x-2.5=r
8.7 x-2.5=-21.75
when you multiply it by a negative the inequality symbols will swap so the answer is r ≥ −21.75
r ≤ -21.75
Forming the equation,
→ r ÷ (-2.5) ≤ 8.7
Then the value of r will be,
→ r ≤ 8.7 × (-2.5)
→ r ≤ -21.75
Hence, value of r is -21.75.
