solve for x: −4|x + 5| = −16 (2 points)
x = 21 over 4, x = − 11 over 4
x = −1, x = 9
x = −1, x = −9
no solution

Step-by-step explanation:

Once again, we have a problem with the |x| in it, so like last time, every number that is the outcome within those brackets, is positive.

Let us check:

A. x = 21 over 4 and x = -11 over 4

This one is a very simple to say no to, as we are talking about decimals (if you convert into decimals at this point), as in -16 there are no decimals.

False.

B. x = -1 and x = 9

-1 is correct. But 9 is not. Why? Here:

9 + 5 is 14

14 the multiplied by -4 does not equal -16

False.

C. x = -1 and x = -9

Like what I said before, -1 is  correct, now in this answer, -9 is also correct.

Unlike the last one, this one is -9 + 5 which is -4, then since it is inside the positive brackets, the number 4 becomes positive.

4 * -4 = -16

True.

The last one is incorrect. You know why

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

9 x 8 divided by (5-3)=36
