Evaluate each algebraic expression for x = 2 and y= -5. |x+y|

Guida verificata passo dopo passo
1
Identify the given values: \(x = 2\) and \(y = -5\).
Substitute the values of \(x\) and \(y\) into the expression \(|x + y|\) to get \(|2 + (-5)|\).
Simplify inside the absolute value by performing the addition: \(2 + (-5) = 2 - 5\).
Calculate the result of the addition inside the absolute value: \(2 - 5 = -3\).
Evaluate the absolute value of the result: \(|-3|\), which is the distance from zero on the number line.

Absolute Value

The absolute value of a number is its distance from zero on the number line, always expressed as a non-negative value. For example, |x + y| means you first compute x + y, then take the absolute value of the result.

Order of Operations

Order of operations dictates the sequence in which parts of an expression are evaluated, typically parentheses first, then addition or subtraction, followed by multiplication or division. Correctly applying this ensures accurate evaluation of expressions like |x + y|.
