To evaluate the expression \( 10 - 2x \) for \( x = 2 \), substitute \( 2 \) into the expression: \[ 10 - 2(2) = 10 - 4 = 6. \] For \( x = \frac{1}{2} \): \[ 10 - 2\left(\frac{1}{2}\right) = 10 - 1 = 9. \] Finally, for \( x = -2 \): \[ 10 - 2(-2) = 10 + 4 = 14. \] So, the evaluated results are: a. 6, b. 9, c. 14.
