Answer is -0.24 mA

**Figure 9-26: Circuit Diagram**

In the circuit shown in Figure 9-26, we need to determine the output current \( I_0 \).

**Components and Layout:**

- The circuit includes two voltage sources: 9V and 6V.
- Three resistors are present with values of 10 kΩ, 30 kΩ, and 25 kΩ.
- An operational amplifier (op-amp) is integrated into the circuit with a 40 kΩ feedback resistor.
- The resistors are connected as follows:
  - 10 kΩ is connected to the 9V source.
  - 30 kΩ is connected to the 6V source, sharing a common ground with the 9V source.
  - The op-amp is connected with a 40 kΩ feedback resistor running from the output back to the inverting input.
  - Another 10 kΩ resistor is connected to the output side, leading to a 25 kΩ resistor, where the output current \( I_0 \) is measured.

This schematic layout is for determining the output current \( I_0 \) in the given circuit configuration.
