Answer:

D) y = 27 · (3)^x

Step-by-step explanation:

Replace x with the x values.

27 · (3)^-2 = 27 · 1/9 = 3

27 · (3)^-1 = 27 · 1/3 = 9

27 · (3)^0 = 27 · 1 = 27

27 · (3)^1 = 27 · 3 = 81

17 · (3)^2 = 27 · 9 = 243

D is your answer.

Hope this helps

Which equation has a y-intercept at (0,3) and a x-intercept at (-4,0)

bija089 [108]

Using the two coordinates you can find the equation
------------------------------------
Find slope first
Slope $= \frac{y2-y1}{x2-x1}$
0 - 3 = -3
-------
-4 - 0 = -4
--------------------------------------------------
Simplify -3/-4
3/4
-----------------------------------------------------------
Your slope is 3/4 and the Y-intercept as mentioned in the question is "3"
----------------------------------------------------------------------
So your equation is y = 3/4x + 3

Order these numbers from least to greatest.<br> 2.68, 2.6081, 3.119, 2.6

kykrilka [37]

Answer:

2.6, 2.6081, 2.68, 3.119

Step-by-step explanation:

Look at the number before the decimal first. After look at the decimal points, the one with the smallest amount will be the least greatest (2.6) because it has no numbers after it.

Which of the statements using operations on rational or irrational numbers always results in a rational number?

-BARSIC- [3]

<h3>Hm a irrational number is a number like this:</h3>

$1.999999\inf$

So adding a rational number, like 2, it would be irrational still:

$2+1.999999\inf=3.999999\inf$

That being said, answer C is wrong

Now, what is 2/2? Or 4/1? Whole numbers are one of the 3 types of rational numbers.

$2\ /\ 2=1\\\\4\ / 1=\ 4$

Thus the answer appears to be D

Now lets use the process of elimination to double check the answer:

The wording of your question is what will help us out here:

Which of the statements using operations on rational or irrational numbers <u>always results </u>in a <u>rational number?</u>

Because of that, any of the choices that involve a irrational number can result with another irrational number like so:

$a)\ 1.999\inf+ 1.999\inf=3.888\inf\\\\b)\ 2.999\inf / 1.999\inf= 1.50025\inf$

And there you go, the only answer that hasn't been proven wrong is answer D.

In ΔNOP, \overline{NP} NP is extended through point P to point Q, \text{m}\angle PNO = (x+14)^{\circ}m∠PNO=(x+14) ∘ , \text{m}\a

adelina 88 [10]

Answer:

<OPQ = 23 degrees

Step-by-step explanation:

Given

Interior angles m∠PNO=(x+14) and m∠NOP=(x−1)

Exterior angle = m<OPQ = (5x-2)

The sum of interior angles is equal to the exterior angle, that is;

m∠PNO+m∠NOP = m<OPQ

x+14 + x-1 = 5x-2

2x + 13 = 5x-2

Collect like terms;

2x-5x = -2-13

-3x = -15

x = 15/3

x = 5

Get <OPQ

<OPQ = 5x - 2

<OPQ = 5(5)- 2

<OPQ = 25-2

<OPQ = 23 degrees
