Solve the inequality: −10f+9≤102. Use decimal form to answer to the nearest tenth.
To solve the inequality, we first isolate the variable f.
Starting with the given inequality:
-10f + 9 ≤ 102
Subtracting 9 from both sides:
-10f ≤ 93
Dividing both sides by -10 (and remembering to reverse the inequality because of dividing by a negative number):
f ≥ -9.3
So the solution to the inequality is f ≥ -9.3.
