<h2>Answer:</h2>

The correct answer is:

                Option: B

   B.\ a_n=27(\dfrac{1}{3})^{n-1}

<h2>Step-by-step explanation:</h2>

We are given that the graph passes through (2,9) , (3,3) and (4,1)

Now, the function which models the graph is given by:

a_n=27(\dfrac{1}{3})^{n-1}

when n=2 we have:

a_2=27(\dfrac{1}{3})^{2-1}\\\\i.e.\\\\a_2=27(\dfrac{1}{3})^1\\\\i.e.\\\\a_2=9

when n=3 we have:

a_3=27(\dfrac{1}{3})^{3-1}\\\\i.e.\\\\a_3=27(\dfrac{1}{3})^2\\\\i.e.\\\\a_3=3

when n=4 we have:

a_3=27(\dfrac{1}{3})^{4-1}\\\\i.e.\\\\a_3=27(\dfrac{1}{3})^3\\\\i.e.\\\\a_4=1

Youth tickets(y) cost $2 for a ride, while adult tickets(x) cost $3. The amount of money earned is $54. If all the seats were fi
Paha777 [63]
There are no constants here. But we have x and y here.
We will create an equation which is:
2y+3x=54.
But we will also create a second equation which states the number of seats.
x+y=24.

Now we do the two-equation solving method.
2y+3x=54
-2(x+y=24)

2y+3x=54
-2x-2y=-48

x=6

To solve for y, plug in x into one of the original equations. Which one doesn't matter.

y+6=24
y=18

Answer:

no

Step-by-step explanation:

12x-20x=-8x

so it would be -8x>-40

and you would divide both sides by -8

and get x<5

F(X)= 2x^2 +1. Find and simplify af(X)+b and f(ax+b)
kati45 [8]
Hello,

f(x)=2x²+1
f(ax+b)=2(ax+b)²+1=2(a²x²+2abx+b²)+1=2a²x²+4abx+2b²+1

af(x)+b=a(2x²+1)+b=2ax²+a+b

And f(ax+b)≠af(x)+b not linear

Since it’s supplementary the straight line would equal to 180 degrees

4d - 1 + 105 = 180
4d + 104 = 180
4d = 76
d = 19
