Which statement about this mapping is true?

The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

The mapping does not represent y as a function of x, because there are more x-values than related y-values.

The mapping represents y as a function of x, because each y-value is related to exactly one x-value.

Answers

Answer:

The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

Step-by-step explanation:

See it's not a function

Because In a function every c value has a unique y value.Here there is 4 values for one x .So it's a relation

The statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

WE have been given a domain figure.

We can see that the input values has more than one output values.

therefore, it cannot be a function Because in a function every input value has a unique y value.

Here there is 4 values for one x input.

x = 3

y = 2, 4, 5, 6

So it's a relation

Hence, the statement which is true about this mapping is the mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

Find the equation of a line that contains the points (-3,-1) and (-4, -7). Write the equation in slope-intercept form.

Answers

Answer:

y = 6x + 17

Step-by-step explanation:

First you can find the slope:

m = (y2-y1) / (x2-x1)

m = (-7 - (-1)) / (-4 - (-3))

m = (-7 + 1) / (-4 + 3)

m = -6 / -1

m = 6

_______

Then we can plug what we know into the point-slope form:

y - y1 = m (x - x1)

(you can pick either one of the points to plug in as (x1, y1))

y - (-7) = 6 (x - (-4))

y + 7 = 6 (x + 4)

_______

Now we can change the point-slope form into slope-intercept form by solving for y:

y + 7 = 6 (x + 4)

y + 7 = 6x + 24

y = 6x + 17

2y = -4x - 12                    Divide by 2

Jinches
a. Maximum volume
b. length of side of square: x=

Answers

Answer:

Step-by-step explanation:

V = x(14 - 2x)(18 - 2x)

V = (14x - 2x²)(18 - 2x)

V = (252x - 28x² - 36x² + 4x³)

V = 4x³ - 64x² + 252x

V' = 12x² - 128x + 252

0 = 3x² - 32x + 63

x = (32 ±√(32² - 4(3)(63))) / (2(3)

x = (32 ± √268) / 6

x = 8.06 inches, which we ignore as this would mean we have no material left at all in the 14 inch dimension.

or

x = 2.60488... 2.60 inches

Vmax = 0.60(14 - 2(2.60))(18 - 2(2.60)) = 292.86478... = 292.86 inches³

Consider the parabola given by the equation: y = 1x^2 - 12x + 27

A) the vertex = (_,_)

B) the y-intercept is the point (0,_)

C) find the two values of x that corresponds to the x intercepts of the parabola and write them as a list separated by commas:
X= ___

Answers

Answer:

vertex: (6, -9)

y intercept: (0, 27)

X = 3, 9

Step-by-step explanation:

Finding Vertex (Part A)

Consider the formula -b/2a. This formula gives you the x-coordinate of the vertex.

y = 1x^2 - 12x + 27

a = 1

b= -12

c =27

-b/2a = - (-12)/2(1) = 12/2 = 6 (x-coordinate of vertex)

When solving for the y-coordinate of the vertex you will need to substitute your 'x" back into the equation.

y = 1(6)^2 - 12(6) + 27

y = 36 - 72 + 27 = -9 (y-coordinate of vertex)

--------------------------------------------------------------------------

Y- Intercept (Part B)

When looking for the y-intercept your "x" must always be 0.

Substitute 0 in every "x" in equation.

y = 1(0)^2 - 12(0) + 27

y = 27

y intercept: (0, 27)

------------------------------------------------------------------------------

X- Intercepts (Part C)

To find the values of "x" factor.

y = 1x^2 - 12x + 27

0 = 1x^2 - 12x + 27

0 = (x  - 3     )(x   -  9 )

(x-3) = 0             (x-9) = 0

x = 3                    x = 9

Answers

Given 2y = 5(3 + y):

You’ll have to solve for y:

Start by distributing 5 into (3 + y):

2y = 5(3 + y)
2y = 15 + 5y

Subtract 15 from both sides:
2y - 15 = 15 - 15 + 5y

2y - 15 = 5y

Then, subtract 2y from both sides:
2y - 2y - 15 = 5y -2y

-15 = 3y

Then , divide both sides by 3 to solve for y:

-15/3 = 3y/3

-5 = y

Therefore, y = -5
Answer : Y = -5

What is the equation of the line that passes through the point (2, 1) and has a
slope of 3/2?

Answers

Given :-

A line having a slope of 3/2 passes through (2,1) .

To Find :-

The equation of the line .

Answer :-

According to the question ,

m = 3/2 Point = (2,1)

We know Point slope form of the line as ,

y - y¡ = m ( x - x ¡ )

Substitute ,

y - 1 = 3/2 ( x - 2 ) y - 1 = 3/2x - 3/2*2y - 1 = 3/2x - 3 2( y -1) = 3/2x *2 - 3*22y - 2 = 3x - 6 3x - 2y -4 = 0

Hence the equation of the line is 3x -2y-4=0 .

Answer:

Step-by-step explanation:

Use the form y = mx + b and plug in your known point

y = 3x/2 + b

1 = 3(2)/2 + b

1 = 3 + b

b = -2

y = 3x/2 - 2

Although Carina wasnt an excellent runner when she first joined the team two years earlier, she practiced all the time and soon began to win almost every race in which she competed. Carina was doing so well that she thought she might become the winningest track and field athlete in her schools history!2One afternoon at track practice, Coach Winder nabbed everyones attention to introduce a new athlete. This is Roberto," he said. "He just transferred to our school from Greensboro Middle School. Please welcome Roberto to the team! 3The members of the team clapped and jostled each other as they tried to shake Robertos hand. As the team captain, Carina shook Robertos hand first. She introduced herself and told Roberto that she was excited to have another team member. Roberto told Carina that he had been reluctant about joining the team, but Carina assured him that he would have a marvelous time. 4The next day, the members of the track team stretched before running some sprints. Carina told Roberto that he could race with her. Dont worry, she said. Ill go easy on you because its your first practice. 5Carina and Roberto lined up at the starting blocks. When they heard the CRACK of the starting pistol, Roberto and Carina started. After a short distance, Carina realized that Roberto was no longer beside her. She turned to see how far behind he had fallen, but to her amazement, Roberto was not behind her. She looked up and saw Roberto surging ahead. His feet moved as fast as lightning! When Carina realized that she was about to lose, she ran as vigorously as she could; however, it wasnt enough. Roberto triumphed. Carina seemed almost paralyzed with shock, but she managed to smile and congratulate him. 6Over the next few weeks, Roberto became a phenomenon on the track. No matter how hard Carina trained, she could never beat Roberto. 7One evening after a track meet, Carina was desolate. Roberto had won first place, and Carina had come in third! She considered hanging up her running shoes and quitting the team. Just as she was about to call Coach Winder, her father entered the living room. Carina explained her situation to him. 8If winning is so important to you that you cant merely have fun being a member of the team, said Carinas father, then I guess quitting is your only option. But, before you make your decision, think about why you originally joined the team. 9The next day, Carina walked into Coach Winders office and handed him a slip of paper. Coach Winders eyes widened as he read it. Then, he closed the note and shook his head approvingly. 11Thats right, Carina said with a smile, Id like Roberto to serve as co-captain of the team.
