If x=3, y=-4, and z=2, what is the value of xyz-4z?

  1. -22

  2. -30

  3. 22

  4. 30

The correct answer is: -30

To find the value of the expression xyz - 4z when x = 3, y = -4, and z = 2, we first need to calculate the product of x, y, and z. Calculating xyz: xyz = 3 * (-4) * 2 First, calculate 3 * (-4): 3 * (-4) = -12 Next, multiply this result by 2: -12 * 2 = -24 Now, we need to calculate 4z: 4z = 4 * 2 = 8 Now we can substitute these values back into the original expression: xyz - 4z = -24 - 8 Now, subtract 8 from -24: -24 - 8 = -32 This indicates there might be an error in the response, as the calculation leads us to a different result. The correct value of xyz - 4z is -32. The available options do not include -32, suggesting that a recalculation of the options or values may be necessary to find a match.
