To solve the inequality \(42 \leq 26 + 8m\), we will isolate \(m\).
-
Subtract 26 from both sides: \[ 42 - 26 \leq 8m \] \[ 16 \leq 8m \]
-
Next, divide both sides by 8: \[ \frac{16}{8} \leq m \] \[ 2 \leq m \]
This can be rewritten as: \[ m \geq 2 \]
The solution to the inequality is \(m \geq 2\).
Graphing the Solution
When graphing this inequality on a number line:
- Place an open circle (or a filled circle, depending on your notation) at 2 to indicate that \(m\) is included in the solution (since it is greater than or equal to).
- Shade the line to the right of 2 to represent all values of \(m\) that are greater than or equal to 2.
Here’s how the number line would look:
<---|---|---|---|---|---|---|---|---|--->
0 1 2 3 4 5 6 7 8
●================>
The filled circle at 2 indicates that 2 is included in the solution, and the shaded area to the right indicates that all greater values are included.
