7
23
-7
-23

Answer 1

After substituting the given values into the expression | x + y | with x = 8 and y = -15, and applying the absolute value function, the result of the evaluated expression is 7.

Step-by-step explanation:

To evaluate the expression | x + y | with x = 8 and y = -15, you simply substitute the values of x and y into the expression and then apply the absolute value function.

Step 1: Substitute the values into the expression.

x + y = 8 + (-15) = 8 - 15 = -7

Step 2: Apply the absolute value function, which turns negative numbers into positive numbers.

| x + y | = | -7 | = 7

Therefore, the evaluated expression | x + y | is 7.

Answer 2

8+-15=-7 so your basically subtract if there is a positive and negative together
