Answer :
Final answer:
The inequality 4x <= 9x simplifies to 0 <= x, which means that x is greater than or equal to 0. This simplification is done by subtracting 4x from both sides and then dividing by 5.
Explanation:
To find an equivalent inequality to 4x ≤ 9x, you need to subtract 4x from both sides of the inequality to isolate terms. The inequality will then become 0 ≤ 5x. If you divide both sides of the inequality by 5, we get 0 ≤ x, which means x is greater than or equal to 0. So, the correct equivalent inequality is 0 ≤ x.
Step-by-step:
- Subtract 4x from both sides: 4x - 4x ≤ 9x - 4x
- Simplify: 0 ≤ 5x
- Divide by 5: 0/5 ≤ x
- Simplify: 0 ≤ x
