Solve for a.

4a–17>3 or 9a–8<10
Write your answer as a compound inequality with integers.

1 answer

To solve the inequality \( 4a - 17 > 3 \) or \( 9a - 8 < 10 \), we will solve each part separately.

  1. For the first inequality: \[ 4a - 17 > 3 \] Add 17 to both sides: \[ 4a > 3 + 17 \] \[ 4a > 20 \] Now, divide by 4: \[ a > 5 \]

  2. For the second inequality: \[ 9a - 8 < 10 \] Add 8 to both sides: \[ 9a < 10 + 8 \] \[ 9a < 18 \] Now, divide by 9: \[ a < 2 \]

Now we have two separate inequalities:

  • \( a > 5 \)
  • \( a < 2 \)

The solution is \( a < 2 \) or \( a > 5 \).

In interval notation, this can be expressed as: \[ (-\infty, 2) \cup (5, \infty) \]

As a compound inequality with integers, we express it as: \[ a < 2 \quad \text{or} \quad a > 5 \]

This is the final answer.
