What is the solution to the inequality 28 > 4 – 2p?

{p | p > –12}
{p | p < –12}
{p | p > 12}
{p | p < 12}

1 answer

To solve the inequality \( 28 > 4 - 2p \), we first rearrange it to isolate the variable \( p \).

  1. Subtract \( 4 \) from both sides:

\[ 28 - 4 > -2p \]

\[ 24 > -2p \]

  1. Now, divide both sides by \(-2\). Remember that when you divide or multiply by a negative number, you need to flip the inequality sign:

\[ \frac{24}{-2} < p \]

\[ -12 < p \]

This can also be written in interval notation as \( p > -12 \).

Thus, the solution to the inequality is:

\[ {p | p > -12} \]

Therefore, the correct answer is:

\({p | p > -12}\)
