<span>Well, think of it this way? How many times does 5 go into 9?
5 * 1 = 5
5 * 2 = 10
So 5 goes into 9 one time. Then you have to subtract that 5 from 9 to be left with your fraction value.
1 and 4/5 is your mixed number.</span>

<u>Step 1: Find the answer</u>
Answer: 
Answer:
You could just replace all the given possible values of k in the inequality and see which ones are solutions, but let's solve this in a more interesting way:
First, remember how the absolute value works:
IxI = x if x ≥ 0
IxI = -x if x ≤ 0
Then if we have something like:
IxI < B
We can rewrite this as
-B < x < B
Now let's answer the question, here we have the inequality:
I-k -2I < 18
Then we can rewrite this as:
-18 < (-k - 2) < 18
Now let's isolate k:
first, we can add 2 in the 3 parts of the inequality:
-18 + 2 < -k - 2 + 2 < 18 + 2
-16 < -k < 20
Now we can multiply all sides by -1, remember that this also changes the direction of the signs, then:
-1*-16 > -1*-k > -1*20
16 > k > -20
Then k can be any value between these two limits.
So the correct options (from the given ones) are:
k = -16
k = -8
k = 0
Answer:
9/16
Step-by-step explanation:
Derivative rule:
Here, n=-1, so
Evaluating this at x=-4 gives 9/16
The answer is 4^3 and I believe that this is right
