Solve the inequality and graph the solution.

16(g+5)–20≥12
Plot the endpoints. Select an endpoint to change it from closed to open. Select the middle of the segment, ray, or line to delete it.

1 answer

To solve the inequality \( 16(g + 5) - 20 \geq 12 \), we'll first simplify the left side.

  1. Distribute \( 16 \): \[ 16g + 80 - 20 \geq 12 \]

  2. Combine like terms: \[ 16g + 60 \geq 12 \]

  3. Subtract \( 60 \) from both sides to isolate the variable term: \[ 16g \geq 12 - 60 \] \[ 16g \geq -48 \]

  4. Divide both sides by \( 16 \): \[ g \geq \frac{-48}{16} \] \[ g \geq -3 \]

Now we have the solution \( g \geq -3 \).

Graphing the Solution

  1. The endpoint of the solution is at \( g = -3 \).
  2. Since the inequality is \( g \geq -3 \), the endpoint at \( g = -3 \) is included in the solution, so we will use a closed dot at \( -3 \).
  3. The solution includes all values greater than \(-3\), extending to infinity.

Graph Representation

  • Mark the point \( -3 \) with a closed dot.
  • Draw a ray starting from \( -3 \) and extending to the right (towards positive infinity).

Final Representation:

  • Closed dot at \( -3 \) (indicating it is included).
  • Arrow extending to the right from \( -3 \) indicating all values greater than \(-3\) are included in the solution.

In summary, the inequality \( g \geq -3 \) signifies all values of \( g \) that are equal to or greater than \( -3 \).
