On a field trip there are 3 adults for every 45 students. Which graph models a relationship with the same unit rate?

Answer:

Step-by-step explanation:

as x+6 is the quotient, you need to use -6

-6 |  4   -3   +5       6

x         -24  +162 -1002

add

       4  -27  167  -996

f(x)= 4x^2 -27x +167 - 996/(x+6)

Lets check

(x+6)(4x^2 -27x +167)= 4x^3 -27x^2 +167x + 24x^2 - 162x + 1002 =

= 4x^3 - 3x^2 +5x +1002

1002-996= 6

So we have the correct solution: 4x^2 -27x +167 - 996/(x+6)

Answer:

Step-by-step explanation:

6y+4-3y=-5+y+17

6y-3y-y= -5+17-4

2y=8

y=4

Answer:

y = 4

Step-by-step explanation:

6y + 4 - 3y = -5 + y + 17

First, we have to combine like terms on each side of the equation:

3y + 4 = y + 12

Then, we have to combine the terms from both sides of the equation:

3y + 4 = y + 12

      -4          -4

3y = y + 8

-y    -y

2y = 8

Then, we divide so we only have y on the left side:

2y = 8

/2     /2

y = 4

The winner got a total of 42 votes.

This can be defined as a number or ratio expressed as a fraction of 100. It is usually calculated by parts/whole × 100.

In this scenario, Jane was the winner as she got a higher percentage of votes. To calculate the exact number of vote we have to do the following:

70%/100% × 60 = 42 votes.

Therefore, the total number votes the winner got is 42.

Step-by-step explanation:

Answer:

1. Second option. Value of the first column is less than the second column's value

2. Right by 4 units

3. (-1, -6)

4. Function 1 and 2 have the same maximum

5. 15

Step-by-step explanation:

1.  look at the photo

2. look at the photo

3. look at the photo

4. I used the formula -b/2a to find the x-value of the vertex. I got 0 (there is no b) and then I subbed it into the function and y = 9. Hence the vertex of the first function is (0,9) which is the same as the second function

5. The vertex of the f(x) is (-3, -3) and the vertex of g(x) is (3, 12). To find the difference you would do 12 - (-3), which would become 12 + 3 = 15

Hey there!

=> 50 1/8 {improper fraction}

=> 401/8 {proper fraction}

=> 401/8 ÷ 2.5

=> 50.125 ÷ 2.5 { Divide}

=> 20.05

Convert [tex]20.05[/tex] to fraction

Rewrite the decimal number as a fraction with 1 in the denominator

20.05=20.05/1

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100

20.05/1×100/=2005/100

Find the Greatest Common Factor (GCF) of 2005 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2005÷5/100÷5=40/120

Simplify the improper fraction,

Answer:

2n + 2

Step-by-step explanation:

To get the answer you must do distributive. This means you have to multiply 2 and  N and 2 and 1. Next, after you multiply these answers you put them together with whatever operation sign is there. In this case, the operation sign here is an addition. Therefore the answer would be 2n + 2.

Answer:

w = 99 pounds

Step-by-step explanation:

The problem states that Mary's weight is given by the equation:  

w = 92 + g - 1

I believe the "-1" should be "-x."  -1 would mean that Mary lost 1 pound.  But we know that Mary lost 8 pounds, which is designated as x.

The correct equation is:

w = 92 + g - x

============

Using the correct equation, and g=15 and x=8, Mary's new weight is:

w = 92 + 15 - 8

w = 99 pounds

Answer:

slope is 3/2

Step-by-step explanation:

you can find slope by comparing the vertical height / horizontal height of two points on the line

for example, we can use points (20,0) and (40,30)

vertical height is 30 minus 0 which is 30

horizontal height is 40 minus 20 which is 20

so slope is 30/20 or 3/2

Answer:

[tex]Cost= \$47[/tex]

Step-by-step explanation:

Given

Vertices: (−1, 5), (4, 2), and (9, −4)

Cost per foot = $8

Required

Determine the cost of fencing (-1, 5) and (4, 2)

First, we need to determine the distance between (-1, 5) and (4, 2)

Distance, d is calculated as follows:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Where

[tex](x_1,y_1) = (-1, 5)[/tex]

[tex](x_2,y_2) =(4, 2)[/tex]

So, we have:

[tex]d = \sqrt{(4 - (-1))^2 + (2 - 5)^2}[/tex]

[tex]d = \sqrt{(4 +1))^2 + -3^2}[/tex]

[tex]d = \sqrt{5^2 + -3^2}[/tex]

[tex]d = \sqrt{25 + 9}[/tex]

[tex]d = \sqrt{34}[/tex]

[tex]d = 5.83095189485[/tex]

[tex]d = 5.831[/tex] -- Approximated;

If the cost of 1 foot is $8.

5.831 feet will cost:

[tex]Cost= 5.831 * \$8[/tex]

[tex]Cost= \$46.648[/tex]

[tex]Cost= \$47[/tex] -- Approximated
