**Answer:**

B

**Step-by-step explanation:**

The dependent variable is y, that represents the years

**Given:**

First term of an arithmetic sequence = 5

Second term = 3

**To find:**

The explicit formula for the given arithmetic sequence.

**Solution:**

We have,

First term:

Second term:

Common difference is

Now, the explicit formula for an arithmetic sequence is

where, a is first term and d is common difference.

Putting a=5 and d=-2, we get

It can also be written as

Here, n is an integer greater than or equal to 1.

Domain is the set of input values.

**Therefore, the explicit equation is or and domain is all interest greater than or equal to 1.**

**Answer:**

**Step-by-step explanation:**

You have to realize that the absolute value function will change the sign of its argument only if that argument is negative.

108. |x -7| = x -7 . . . . . true for x-7≥0

** x ≥ 7** . . . . makes the statement true

1a. When m < 9, the value 6m is less than 54, so 6m-54 < 0. That means the absolute value function changes the sign of its argument:

**54 -6m** . . . . . simplified form for m < 9

__

1b. |y -x| = **y -x** . . . when y > x, the argument of the absolute value is positive
