The prices for different lengths of ribbon sold at a fabric store are shown in the table.

Which statement BEST justifies whether or not the relationship between the length and price represents a function?

A.
This relationship does not represent a function because it relates inches and dollars.
B.
This relationship represents a function because no length of ribbon has more than one price.
C.
This relationship represents a function because the price per inch decreases as the length of ribbon increases.
D.
This relationship does not represent a function because the prices of different lengths of ribbon are all different.

Answer:

1/2

Step-by-step explanation:

Slope equals rise over run. To find this use two points that land evenly on the graph then count how ever many spaces up and then to the side. In this case, it goes up 1 and right 2, so put that into fraction form, 1/2, and that is your answer.

Answer:2.5v+5>5v

Step-by-step explanation:this definitely right

Given:

Line a is perpendicular to line b .

Line a passes through the points (1,-8) and (9,-12) .

Line b passes through the point (-8, -16).

To find:

The equation of b.

Solution:

Line a passes through the points (1,-8) and (9,-12) . So, slope of line a is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m_a=\dfrac{-12-(-8)}{9-1}[/tex]

[tex]m_a=\dfrac{-12+8}{8}[/tex]

[tex]m_a=\dfrac{-4}{8}[/tex]

[tex]m_a=-\dfrac{1}{2}[/tex]

Product of slopes of two perpendicular lines is -1.

[tex]m_a\times a_b=-1[/tex]

[tex]-\dfrac{1}{2}\times a_b=-1[/tex]

[tex]b=2[/tex]

Slope of line b is 2.

If a line passing through a point [tex](x_1,y_1)[/tex] with slope m, then equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

Line b passing through (-8,-16) with slope 2. So, equation of line b is

[tex]y-(-16)=2(x-(-8))[/tex]

[tex]y+16=2(x+8)[/tex]

[tex]y+16=2x+16[/tex]

Subtract 16  from both sides.

[tex]y=2x[/tex]

Therefore, the equation of line b is [tex]y=2x[/tex].

Answer:

y= -4x - 5

Step-by-step explanation:

5 is your y-intercept

The slope of the line which passes through the points (3,5) and (2,0) is 5

From the question,

We are to determine the slope of the line

The slope of a line with two given points can be determined from the formula

[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Where m represents the slope

From the given information

x₁ = 3

y₁ = 5

x₂ = 2

y₂ = 0

Putting these into the formula,

We get

[tex]m = \frac{0-5}{2-3}[/tex]

Then,

[tex]m = \frac{-5}{-1}[/tex]

∴ m = 5

Hence, the slope of the line which passes through the points (3,5) and (2,0) is 5

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(82, −96) and (87, −86)

We have

[tex]m = \frac{ - 86 - - 96}{87 - 82} = \frac{ - 86 + 96}{5} = \frac{10}{5} = 2 \\ [/tex]

Step-by-step explanation:

Answer:

x = 15°

Step-by-step explanation:

∠2 and ∠4 are same-side interior angles, meaning they add up to 180

2x + 10 + 4x + 80 = 180

Rearrange (collect like terms)

6x = 180 - 80 - 10

6x = 90

x = 15°

Answer:

Step-by-step explanation:

∠2 = 2x + 10

∠4 = 4x + 80

∠2 and ∠4 are supplementary angles, this mean ∠2 + ∠4 = 180

2x + 10 + 4x + 80 = 180

combine similar terms: 6x = 180 - 80 - 10

simplify: 6x = 90

solve for x = 90 / 6

               x = 15

The required equation of the parallel track that runs through the point (4 , -2) is  2x + 5y = −2.

The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decided to create parallel tracks through this portion of the railway.The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2) TO determine.

The equation is the relationship between variables and represented as y=ax + b  is an example of a polynomial equation.

Equation of the southbound track,
2x + 5y = 15
slope of the above equation is m = -2/5

Since the slope of the parallel lines are equal.

The equation of the parallel northbound track that runs through the point (4, – 2),
(y + 2) = -2/5 (x - 4)
5(y + 2) = -2 (x-4)
5y + 10 = - 2x +8
2x + 5y = 8-10
2x + 5y = -2

Thus, the required equation  of the parallel track that runs through the point (4 , -2) is  2x + 5y = −2.

Answer:

x = -1/2 or -0.5

Step-by-step explanation:

4(2x - 2) + 2 = 4(x - 2)

open the parenthesis

8x - 8 + 2 = 4x - 8

add 8 to both sides of the equation

8x - 8 + 2 + 8 = 4x - 8 + 8

combine like terms

8x + 2 = 4x

subtract 4x from both sides of the equation

8x - 4x + 2 = 0

4x + 2 = 0

subtract 2 from both sides of the equation

4x + 2 - 2 = 0 -2

4x = -2

divide both sides by 4

4x/4 = -2/4

x = -1/2

Answer:

46

Step-by-step explanation:

Lets arrange the numbers first

23, 27, 32, 32, 36, 38, 46, 49, 51, 55, 58, 59, 63

so find how many numbers there are

- 13

the middle number of 13 is 7

so the 7th number should be the median of this sum

7th number - 46

Answer - 46

Hope you understand

:-)

The data given results in this list

{23,27, 32,32,36,36, 46,49, 51,55,58,59, 63}

The middle most value is 46 since there are 6 items below it {23,27,32,32,36,36} and 6 items above it {49,51,55,58,59,63}.

It might help to cross off the outer values and work your way in so you can spot the middle value easier.
