Answer 1

Answer:

7/5 y --> y+ 2/5y

0.68y --> y - 0.32y

3/5y --> y - 2/5y

1.32y --> y+ 0.32y

Step-by-step explanation:

Pretend there is a 1 in front of each y that doesn't have a number (coefficient) in front of it. 1 = 5/5, and then just solve for the fraction expressions.

Answer 2
7/5y —> y+2/5y
0.68y —> y-0.32y
3/5y —> y-2/5y
1.32y —> y+0.32y

Is the table above proportional or non-proportional?

Answers

Answer: I think you should divide them all and if you get the same answer it’s proportional if you don’t get the same answer it’s non-proportional

Step-by-step explanation:

Answer:

It is non-proportional.

Step-by-step explanation:

The table is non-proportional because it expresses a curved line instead of a straight line.

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

The perimeter of the original rectangle on the left is 30 meters. The perimeter of the reduced rectangle on the right is 24 meters. What is x, the width of the original rectangle on the left? Round to the nearest hundredth if necessary.

A) 5 meters
B) 8 meters
C) 10 meters
D) 12 meters

Answers

X=5



Explanation:


If the triangle on the rights perimeter is 24 and two of the lengths are 8 then we know 8+8=16 24-16=8 8/2=4
So the triangle on the right has the numbers 8 and 4 as it’s length and width

So then you would find out how much it was dilated to get from 30 to 24
30/24 and you get 1.25 so you multiply 4 by 1.25 and get 5, and then to double check you can multiply 8 by 1.25 and get 10 then add it all together
5+5+10+10=30 so you know that’s correct.

What is the multiplicative rate of change of the function?

1/3
2/3
2
9

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!

Hope this helps!!

The table shows the relationship between X and Y.

X | 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).

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)

therefore ,

the correct solution is
