Question

Evaluate the expression. \(-4 x y\) when \(x=-2\) and \(y=-6\)

Short answer

The evaluated expression is -48.

Step-by-step solution

Substitute the given values

Replace \(x\) with -2 and \(y\) with -6 in the original expression. This gives us: \(-4*(-2)*-6\).

Apply order of operations

When dealing with multiple operations in the same expression, we apply the rules of order of operations, also known as BIDMAS or PEMDAS. However, in this case, there is only multiplication. So we proceed from left to right. This results in: \(8*-6 = -48\).
