What is the multiplicative rate of change of the function?

1/3
2/3

Answers

Answer:

it is 2/3.

Step-by-step explanation:

please mark as brainliest .

2/3

As x increases by 1
Y decreases by a rate of 2/3.
6x2/3=4
4x2/3=8/3
And so on
To find 2/3, all you need to do is find how y is changing.
First of all, we know that y is decreasing as x increases so the rate is less than 1.
Take y2/y1 to get m or the rate
Ex. 4/6=2/3 which is less than 1!

The table shows the relationship between X and Y.

3 | 163.5

6 | 327

11 | 599.5


Which equation models this relationship?

A. y = 53x

B. y = 53.5x

C. y = 54x

D. y = 54.5x


PLEASE ANSWER I NEED THIS THE ANSWER NOW

Answers

Answer: C. y = 54x



Explanation:

Hope this helps you :)

An equation which models the relationship between X and Y is

y = 54.5x

The correct answer is option (D) y = 54.5x

What is equation?

"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."

From given data we can observe that,

163.5/3 = 54.5                           ...................(1)

327/6 = 54.5                              ...................(2)

599.5/11 = 54.5                          ...................(3)

From (1), (2) and (3),

y/x = 54.5

⇒ y = (54.5)x

Therefore, an equation which models the relationship between X and Y is y = 54.5x

The correct answer is option (D).

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs. After selling 101010 tickets, they were still at a net loss of \$800$800dollar sign, 800 (due to the production costs). They sold each ticket for \$70$70dollar sign, 70.

Answers

Answer:

Price of each ticket = $70

The revenue generated from sales of 10 tickets = 70 x 10 = $700

After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500

Net Profit = Revenue - Cost

Revenue from n tickets will be = 70n

Cost = $1500

So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

Step-by-step explanation:

we have that

5x – 3y – x + 6z

5x – x – 3y + 6z------> this step is correct

5 + 3yz------> is not correct

because

1) 5x-x=5---> is not correct

the correct is

5x-x=4x

2) -3y+6z=3yz-----> is not correct

the correct is

-3y+6z=3*(2z-y)

Solve for x:
(-3/2)x - 9 = -27

Select one:
a. −24
b. −12
c. 11
d. 12

Answers

This is what the equation looks like: [tex]\frac{-3}{2}x - 9 = -27[/tex]

First, we transpose the terms to the other side. So after transposing [tex]-9[/tex], you get: [tex]\frac{-3}{2}x = -27 + 9[/tex]

Add them and you get: [tex]\frac{-3}{2}x = -18[/tex]

Next we transpose the coefficient of [tex]x[/tex] which is [tex]\frac{-3}{2}[/tex] to the other side, and while doing so the operation changes to a division. When dividing rational numbers, you take the reciprocal so you get: [tex]x = -18 * \frac{-2}{3}[/tex]

Multiply them and you get: [tex]x = 12[/tex]

Therefore, Option D is the correct answer :D
