Which relationship between x and y in the equation shows a proportional relationship?

A y=x/2 + 3
B y = 2x + 6
C y = 12x
D y=12/x

I believe it would be negative 9 because your subtracting by twelve again. I hope that helped

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4

Answer:

£7.80

Step-by-step explanation:

Since you multiply 2 by 3 to get 6, we are going to multiply 2.6 by 3

2.6 x 3 = 7.8

Thus the cost of 6 litres of lemonade is £7.80

Answer:

=20a−6b−160

Step-by-step explanation

−8(20−3b)−5(6b−4a)

Answer:

a = 6, b = - 12

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms to those on the right side.

a(4x - 10) ← distribute parenthesis

= 4ax - 10a

Compare to 24x + 5b , then

4a = 24 ( divide both sides by 4 )

a = 6

Then

5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )

b = - 12

Answer:

Step-by-step explanation:

4 times 3x = 12x

4 times 6 = 24

Answer:

-43/50

(decimal) = -0.86

Step-by-step explanation:

Find the LCD which is 50.

16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50

3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50

subtract them which will give you -43/50

Answer:

m = 21

Step-by-step explanation:

12 = 3(m - 17)

12 = 3m - 51 (Found using the distributive property)

63 = 3m (Found by adding 51 to both sides)

21 = m (Found by dividing both sides by 3)

Hope this helps :)

Answer:

You can choose x as any value like x = 7

if x were to equal 7 then

the equation would be y = 2 times 7 - 1

2 times 7 = 14 and 14-1 = 13

y would be 13 ifi x was 7

so you can graph the point 7,13

Answer:

Circumference = 12π m

Step-by-step explanation:

The area of the circle, A = 36π

We need to find the circumference of the circle.

The area of a circle is given by :

[tex]A=\pi r^2\\\\36\pi=\pi r^2\\\\r=6\ m[/tex]

The circumference of a circle is given by :

[tex]C=2\pi r\\\\C=2\pi \times 6\\\\C=12\pi\ m[/tex]

So, the circumference of the circle is 12π meters.

Answer:

New England quarterback Tom Brady has the Patriots rolling again. ... In Week 2, they shut out the hapless Miami Dolphins, 43-0. ... Their start to 2019 has been so strong, even against opponents with a combined record ... and regress their win-loss records to account for the small number of games played.

Step-by-step explanation:

The number of games they won is 12 and the number of games they lost is 4 based on the given ratio.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Suppose the number of games they won is W and the number of games they lost is L.

As per the given

Total games L + W = 16

Ratio W/L = 3/1

W = 3L

L + 3L = 16

4L = 16

L = 4

And, W = 3 x 4 = 12

Hence"The number of games they won is 12 and the number of games they lost is 4 based on the given ratio".

Answer:

45 g de oxido de hierro (III) liberarán 18.9 L de CO₂

Step-by-step explanation:

La reaccion quimica es la siguiente:

Fe₂O₃ (s) + 3CO (g)  →  2Fe (s) + 3CO₂ (g)

1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.

Pasamos la masa de F₂O₃ a moles:

159.6 g . 1 mol /159.7g = 1 mol de oxido

Entonces, aplicamos la regla de tres:

1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.

Ahora calculamos los nuevos moles:

45g . 1 mol /159.7 g = 0.282 moles

Aplicamos la regla de tres:

Si un mol de oxido produce 3 moles de CO₂

0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂

Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:

Si 3 moles de CO₂ ocupan 67.2 litros

0.845 moles ocuparan (0.845  . 67.2/  3 ) =  18.9 litros

Answer:

C. [tex]\frac{9}{14}[/tex] , 9:14 , or 9 to 14

Step-by-step explanation:

With there being 9 teachers and 5 aides, the total number of adults is 14, leaving a fraction of [tex]\frac{9}{14}[/tex] , 9 teachers and 14 adults. Checking to simplify, there are no shared values by 9 and 14, so it is in it's simplest form.
