To evaluate the expression [tex]\( e - \frac{1}{2} f \)[/tex] when [tex]\( e = 15 \)[/tex] and [tex]\( f = 2 \)[/tex], follow these steps:
1. Substitute the given values into the expression:
[tex]\[
e - \frac{1}{2} f \rightarrow 15 - \frac{1}{2} \cdot 2
\][/tex]
2. Compute the multiplication inside the expression:
[tex]\[
\frac{1}{2} \cdot 2 = 1
\][/tex]
3. Subtract the result from the value of [tex]\( e \)[/tex]:
[tex]\[
15 - 1
\][/tex]
4. Perform the subtraction:
[tex]\[
15 - 1 = 14
\][/tex]
Therefore, the value of the expression [tex]\( e - \frac{1}{2} f \)[/tex] when [tex]\( e = 15 \)[/tex] and [tex]\( f = 2 \)[/tex] is [tex]\( 14 \)[/tex].
