What are the solutions to the compound inequality 6c+8≤−10
or 8c+12>20
?

1 answer

To solve the compound inequality \(6c + 8 \leq -10\) or \(8c + 12 > 20\), we will solve each inequality separately.

First Inequality: \(6c + 8 \leq -10\)

  1. Start by isolating \(c\). We will first subtract 8 from both sides: \[ 6c + 8 - 8 \leq -10 - 8 \] Simplifying gives: \[ 6c \leq -18 \]
  2. Next, divide both sides by 6: \[ c \leq -3 \]

Second Inequality: \(8c + 12 > 20\)

  1. Isolate \(c\) by first subtracting 12 from both sides: \[ 8c + 12 - 12 > 20 - 12 \] Simplifying gives: \[ 8c > 8 \]
  2. Now, divide both sides by 8: \[ c > 1 \]

Combining Solutions:

From the solutions obtained, we have:

  • From the first inequality: \(c \leq -3\)
  • From the second inequality: \(c > 1\)

Since this is a compound inequality with "or," the solution includes both parts.

Thus, the solutions to the compound inequality \(6c + 8 \leq -10\) or \(8c + 12 > 20\) are: \[ c \leq -3 \quad \text{or} \quad c > 1 \]

Final Answer: The solution set is \(c \leq -3\) or \(c > 1\).
