Answer:

(a) (-∞, -8) (-6, -4) (-2, ∞)

(b) -6, -2

(d) 5

Step-by-step explanation:

(a) A function is "decreasing" when the y-value decreases as the x-value increases.

⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)

(b) Local maxima are the points on the function where it reaches a maximum.

⇒ maxima at x = -6 and x = -2

(d) 5

You are in talks to settle a potential lawsuit. The defendant has offered to make annual payments of $15,000, $25,000, $40,000,

Sphinxa [80]

Answer:

All payments will be made at the end of the year by using the present value of inflows

Step-by-step explanation:

Present Value Of Inflows = Cash Inflow × Present Value Of Discounting Factor (Rate%,Time Period)

Present Value Of Inflows = $15000/1.037$ + $25000/1.037^{2}$ + $40000/1.037^{3}$ + $60000/1.037^{4}$

Present Value Of Inflows = 125466.3

URGENT 15 POINTS!!!!What is the solution of the system?

ohaa [14]

The elimination method is a sufficient way to solve problems.

2x+y= 20
6x-5y=12

Add 5y to the one equation.

2x+6y= 20
6x= 12

Subtract 2x from both sides.

6y= 20
4x= 12

Divide 6 by 20.
y= 3.3

Divide 4 by 12.
x= 3

I hope this helped you!

Brainliest answer is appreciated!
