Which of the following is a solution to the inequality below?

–8/m ≤ –8

1 answer

To solve the inequality \(-\frac{8}{m} \leq -8\), we can start by isolating \(m\).

Step 1: Multiply both sides by \(-1\) (remember to flip the inequality sign when multiplying by a negative number):

\[ \frac{8}{m} \geq 8 \]

Step 2: Next, we can rewrite the inequality:

\[ \frac{8}{m} \geq 8 \]

Step 3: Multiply both sides by \(m\) (note that we have to consider the sign of \(m\)):

  1. If \(m > 0\):

\[ 8 \geq 8m \ 1 \geq m \quad (dividing\ by\ 8) \]

  1. If \(m < 0\):

Flipping the direction of the inequality gives:

\[ 8m \geq 8 \ m \geq 1 \quad (dividing\ by\ 8) \]

In this case, since \(m < 0\), there are no solutions.

Combining both cases, the solution to the original inequality \( -\frac{8}{m} \leq -8 \) is:

\[ m \leq 1 \]

Plus, \(m\) must be positive to maintain the equality \(-\frac{8}{m} \frac{8}{m} > 0\).

Thus, the solution is:

\[ 0 < m \leq 1 \]

Examples of solutions are any values for \(m\) in the interval \((0, 1]\), such as \(0.5\), \(1\), etc.
