ANSWER:

{(2,4),( 3, 6),(4, 8)}  is a function

Given a relation in x and y, we say y is a function of x if for each element x in the domain, there is exactly one value of y in the range.  It is a rule of correspondence between two nonempty sets, such that, to each element of the first is called domain, there correspondents one and only one element of the second is called range.  

To determine whether it is function or not by using the vertical line test. If the graph passed to Vertical line test it is consider as function. The graph of function defines y as a function of x if no vertical line intersects the graph in more than one point.  

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates for example ( -1, 2), ( 1, 0), (2, 1) . The second example is not a function, because it contains the ordered pairs (1,2) and (1,4). the first set is repeated . These have the same first coordinate and different second coordinates.  

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values.

Answer:

C. [tex]\frac{4}{10}[/tex] and [tex]\frac{10}{25}[/tex]

Step-by-step explanation:

The proportion between these fractions is true. Multiply 4/10 (numerator and denominator) by 2.5 to get 10/25. This is the only correct option.

Answer:

A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were defective. A store clerk generates random numbers to simulate a random sample of this shipment. The clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through 5,000 represent working MP3 players. The results are given.

948 628 87 4,987 938 468 3,589 298 2,459 2,286

Based on this sample, how many of the MP3 players might the clerk predict would be defective?

The manager would expect

defective players in the shipment.

Answer:

f(x) = -3x - 3

Step-by-step explanation:

you can use the point-slope form to help you.  

[tex]y - y_{1} = m (x - x_{1} )[/tex]     m = slope   and  [tex](x_{1} , y_{1}) = (-2, 3)[/tex]

So,  y - 3 = -3(x + 2)

y - 3 = -3x - 6

y = -3x - 3    or f(x) = -3x - 3

[tex]f(x) = -3x - 3[/tex]You can use the standard form y = mx + c to build that linear relationship.

Thus, the needed linear function is: [tex]f(x) = -3x -3[/tex]

The linear function

A linear function of two variables is always an equation of a straight line and can be converted into standard form y = mx + c (assuming m and c to be finite constants and x and y are variables).

m denotes slope of this line and c denotes intercept on y axis by this line.

If linear function is not of two variables, then we can take the output f(x) as value of second variable.

Since the slope is already given, thus, we have the equation as:

y = -3x + c

Now, since the line passes through (-2,3), thus it must satisfy the equation since the point is member of the family of points who constitute this line(and since the equation shows family of such points, thus the point should satisfy the equation).

Thus,

[tex]y = -3x +c|{(x,y) = (-2,3)}\\ 3 = -3 \times -2 + c\\ 3 = 6 + c\\ c = 3 - 6\\ c = -3[/tex]

Thus, we have the equation of the straight line in consideration as:

y = -3x -3

y is function of x, thus can be rewritten as  [tex]f(x) = -3x -3[/tex] (assuming f doesn't represent any other function as we can't use used symbols in a context to prevent ambiguity)

Thus, the needed linear function is: [tex]f(x) = -3x -3[/tex]

Answer:

f(x)=x3

Step-by-step explanation:

If you meant f(x)=x3 by f(x)=x^3 then that would be a cubic equation and not linear?

Answer:

x= 9.04°

7x = 63.28°

8x = 72.32

44.4° + 63.28° + 72.32° = 180°

Step-by-step explanation:

The sum of supplementary angles is 180°

Set up an equation with the given information, then solve for x.

44.4 + 7x + 8x = 180

7x +8x = 180-44.4

15x = 135.6 Divide both sides by 15

x = 9.04

Substitute for x and multiply by 7, then 8 to find the measures of the unknown angles.

Answer:

$33

Step-by-step explanation:

A professional gambler reported that at the end of the first race at the track he had doubled his money. He bet $33 on the second race and tripled the money he came with. He bet $60 on the third race and quadrupled his original bankroll. He bet $68 on the fourth race and lost it, but still had $64 left. With how much money did he start?

Let us represent, the amount of money he had at the start= x

Money after the first race=2x

Money he had after betting=2x-33

Money after the second race=3x

Money he had after betting on the third race=3x-60

Money after the race=4x

Money he had after betting on the fourth race=4x-68

Money after the race=$64

4x-68=64

4x=68+ 64

4x = 132

x=132/4

x = 33

Therefore, he had $33 at the start

Answer:

6 companies.

Step-by-step explanation:

[When you read a stem and leaf plot, the lowest number in the stem category, like 3 for example, would be in the tens place. The numbers in the leaf category are the ones places.]

"At least" tells you that anything equal to or higher the number given is relevant to the question. If we count the amount of numbers that are 63 or over, we have:

63, 69, 70, 73, 76, 78.

These are 6 numbers.

Your answer would be 6 companies.
