Question

which of the following expressions shows the result of subtracting 4 from a number k? k - 4, 4 - k, 4k, k + 4

Explanation:

Step1: Understand the operation

We need to subtract 4 from the number \( k \). In mathematical terms, subtracting a number \( b \) from a number \( a \) is written as \( a - b \).

Step2: Apply to the given problem

Here, \( a = k \) and \( b = 4 \), so the expression should be \( k - 4 \).

Answer:

\( k - 4 \) (corresponding to the first option, e.g., if the first option is labeled as A, then A. \( k - 4 \))
