Answer 2

Sure, I'd be happy to help you evaluate the expression |4x + 9| + 6x when x = -4.

First, let's substitute x = -4 into the expression:

|4(-4) + 9| + 6(-4)

Now, let's perform the calculations step by step:

Step 1: Evaluate the expression inside the absolute value:

|4(-4) + 9| = |-16 + 9| = |-7| = 7

Step 2: Substitute the value we obtained for the absolute value part into the expression:

7 + 6(-4)

Step 3: Perform the multiplication:

7 - 24

Step 4: Finally, perform the addition:

-17

So, when x = -4, the expression |4x + 9| + 6x equals -17.
