Solve for w.

2w–15≥1 or w+17<13
Write your answer as a compound inequality with integers.

1 answer

To solve the inequalities:

  1. First inequality: \( 2w - 15 \geq 1 \)

    • Add 15 to both sides: \[ 2w \geq 1 + 15 \] \[ 2w \geq 16 \]
    • Divide both sides by 2: \[ w \geq 8 \]
  2. Second inequality: \( w + 17 < 13 \)

    • Subtract 17 from both sides: \[ w < 13 - 17 \] \[ w < -4 \]

Now we combine the results of both inequalities:

  • The solution to the first inequality is \( w \geq 8 \).
  • The solution to the second inequality is \( w < -4 \).

Thus, the final compound inequality is: \[ w \geq 8 \quad \text{or} \quad w < -4 \]

In interval notation, this can be represented as: \[ (-\infty, -4) \cup [8, \infty) \]

In terms of integers, your answer is: \[ w \in { w : w < -4 } \quad \text{or} \quad { w : w \geq 8 } \]
