Sophia – College Algebra Unit 1 Milestone 1 Consider the following expression: What is the value of this expression when x = -5?     RATIONALE To find the value of this express ... ion when x = -5, begin by substituting -5 for every instathe expression. Once all instances of x have been substituted with -5, we can evaluate the expression. Tbar acts as a group symbol, separating the expression in the numerator, |-5|, from the ethe denominator, . Evaluate each of them separately before dividing, starting with tvalue of -5. Recall that the absolute value of a number is its non-negative value. The absolute value5. Next, in the denominator, we can square -5. Remember that a negative number squared is always positive so -5 squared is 25. Finalthe fraction. The fraction can be simplified to .
