Question

Evaluate |x - y| + 4 if x = -1, y = 3, and z = -4.

Answer 1

8

Explanation:

Substitute the values in the expression, we have:

`\displaystyle+4`

Evaluate:

`\displaystyle`

Any real numbers in the absolute sign will always be evaluated as positive values. Thus:

`\displaystyle-4\\\\\displaystyle{=8}`

Hence, the answer is 8. A quick note that z-value is not used due to lack of z-term in the expression.
