Question

indicate whether the value of x is a solution or not a solution of the inequality -9x - 4 ≤ 23. select the words from the drop - down list to correctly complete the sentence. x = 3.15 the inequality. a solution not a solution

Explanation:

Step1: Substitute \( x = 3.15 \) into the inequality

Substitute \( x = 3.15 \) into \( -9x - 4 \leq 23 \). First, calculate \( -9x \): \( -9\times3.15=-28.35 \). Then calculate \( -9x - 4 \): \( -28.35 - 4=-32.35 \).

Step2: Check the inequality

Now check if \( -32.35 \leq 23 \). Since \( -32.35 \) is less than \( 23 \), the inequality holds.

Answer:

a solution
