Answer:

(4,9)

Step-by-step explanation:

If f(x) is a function, the function f(x) + a is a function translated a units up vertically. Hence, all the y-coordinates of the coordinates of the points on the function will shift up by a.

For this problem, we need to find corresponding coordinate of (4,4) of f(x) + 5. This means that the y-coordinate of this coordinate will increase by 5 and x will stay the same.

Hence, corresponding point for f(x) + 5 for the point (4,4) would be (4,4+5) OR (4,9).

Answer:

4

Step-by-step explanation:

The numbers in order would be

2, 3, 4, 5, 7

The number in the middle is always the median

Therefore, 4 is the median

Final answer:

The median of the list 5, 7, 2, 4, 3 is 4, once the numbers are arranged in ascending order and we identify the middle value in the set.

Explanation:

To find the median of the list 5, 7, 2, 4, 3, we must first organize the numbers in either ascending or descending order. For this set, arranged in ascending order, we get 2, 3, 4, 5, 7. Since we have n = 5 numbers, the median will be the third value in the ordered set, which is the middle number. Therefore, the median of this data set is 4.

Answer:

Square feet.

Step-by-step explanation:

Feet are an example of what are called linear units. They're used to measure one dimensional things like length, width, or height. Area is two-dimensional, it takes up (flat) space, so we need to measure it in units that do the same thing. The simplest two-dimensional shapes to measure area with turn out to be squares (since the area of a square with side length s is just s²), so we usually measure area in square units. Since our linear units here are feet, the corresponding square units will be square feet.

Answer:

Step-by-step explanation:

The catch is to put this into the quadratic and solve for a b and c in three equations.

x = 1

a(1)^2 + b(1) + c= 0            

a + b + c + 0                (1)

x = - 1

a(-1)^2 + b(-1) + c = 2

a - b + c = 2                 (2)

x = 2

a(2)^2 + b(2) + c = 8

4a + 2b + c = 8            (3)

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

Add 1 and 2 together

a + b + c = 0

a - b + c = 2

2a + 2c = 2           Divide by 2

a + c = 1                       (4)  

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

Multiply (2) by 2

2a - 2b + 2c = 4          (5)

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

Add (5) + (3)

2a - 2b + 2c = 4

4a + 2b + c = 8

6a + 3c = 12               (6)

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

Multiply (4) by 3

3a + 3c = 3                 (7)

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

Subtract (7) from (6)

6a + 3c = 12

3a + 3c =  3

3a = 9                      Divide by 3

3a/3 = 9/3

a = 3

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

Use (4) to find c

a + c = 1

3 + c = 1                  Subtract 3 from both sides

3-3 + c = 1-3

c = - 2

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

Use 1 to find b

3 + b - 2 = 0          Combine 3 and -2

1 + b = 0                Subtract 1 from both sides

b = - 1

Step-by-step explanation:

thomas read faster than  brice!!! wheres the graph btw?

The correct statement of the given ones is that Thomas is reading at a faster rate than Brice.

        [y] = mx + c

Given are Brice and Thomas who are reading the same book. The graph

shows the number of pages that Brice read in a week and the equation

y = 21x + 33 shows the number of pages that Thomas read in a week.

The given equation for Thomas that shows the number of pages that Thomas read in a week is -

y = 21x + 33

The slope of the line is -

m = 21

Thomas is reading 21 pages per week.

For the graph of Brice, it passes through the points (0, 43) and (6, 163). So, we can find the slope as -

m = (163 - 43)/(6 - 0)

m = 120/6

m = 20

Brice is reading 20 pages per week.

Therefore, the correct statement of the given ones is that Thomas is reading at a faster rate than Brice.

A. Car share I hope this helps

The most likely choice for someone needing a car for a few hours to pick someone up from the airport is a car share, due to its convenience and cost-effectiveness for short-term use.

A person who needs a car for just a few hours to pick up a friend from an airport would most likely choose car sharing. This option allows for the short-term use of a car, typically charged by the hour or mile, and is ideal for brief, one-time needs such as an airport pick-up. In contrast, car rental is more suitable for those who need a vehicle for a full day or longer. A car lease is a long-term arrangement, usually spanning several years, and therefore not practical for a few hours of use. Carpooling involves sharing a ride with others going in the same direction but does not provide the flexibility of going to the airport to pick someone up specifically.

When deciding on options like these, one must consider the economic choices and personal needs. Factors like fuel efficiency, car size, and whether all-wheel drive is necessary for local weather conditions should be taken into account for longer-term choices. However, for a few hours of need, car sharing emerges as the most convenient and economical option.

Answer:

C. asymptotes

Step-by-step explanation:

In the figure attached, a sign chart is shown. To fill it out you need to find the function's zeros and asymptotes. The zeros are those x values that makes the function equal to zero, in the example, those are the x values that make the denominator equal to zero (x = -1 and x = 5). In a rational function, the asymptotes are those x values that make the numerator equal to zero (x = -9 in the example)

Function in the example:

[tex]\frac{(-2x-2)(2x-10)}{-9x-81} [/tex]

Final answer:

To complete a sign chart accurately, one needs to use test numbers surrounding each of the function's zeros and asymptotes, determining the sign of the function in those intervals. This helps in understanding the behavior of the function and solving inequalities.

Explanation:

To fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and C. asymptotes which fills the blank correctly. When you're dealing with functions, especially rational functions, the sign of the function can change around its zeros and asymptotes. Zeros are the points where the function crosses the x-axis, and the function's value is zero. Asymptotes, on the other hand, are lines that the function approaches but never touches; the function's value heads towards positive or negative infinity as it gets close to an asymptote.

When creating a sign chart, you select test numbers from intervals between these critical points -- zeros and asymptotes -- to determine if the function is positive or negative in those intervals. This process helps to understand the behavior of the function across its domain and is essential in solving inequalities.

Here's an example:

Identify the zeros and asymptotes of the function.

Place these values in increasing order on a number line to define test intervals.

Choose a test number from each interval and substitute it into the function to check the sign.

Fill in the sign chart with the corresponding signs for each interval.

                    (-7)^(-1)

Apply the rule that:

        x^a

     ----------- = x^(a-b)

        x^b

Then our:

                    (-7)²

                  ----------- = (-7)^(2 - [-1] )  = (-7)^(2+1) = (-7)³

The average cost of a movie ticket in Japan is $17.99 and in Switzerland is $13.82.

To solve the problem of determining the average cost of a movie ticket in Japan and Switzerland, we need to set up a system of equations based on the information given. If we let J represent the cost of a ticket in Japan and S represent the cost of a ticket in Switzerland, we can formulate the following equations from the scenario provided:

3J + 2S = $81.61 (Cost for three tickets in Japan and two in Switzerland)

3S + 2J = $77.44 (Cost for three tickets in Switzerland and two in Japan)

Now we solve the system of equations using substitution or elimination method. For simplicity, we'll use the elimination method:

Multiply the first equation by 3 and the second equation by 2 to make the coefficients of S the same:

9J + 6S = 3 x $81.61 = $244.83

6S + 4J = 2 x $77.44 = $154.88

Subtract the second new equation from the first to eliminate S:

9J + 6S - (6S + 4J) = $244.83 - $154.88

5J = $89.95

Divide by 5 to solve for J:

J = $89.95 / 5 = $17.99

Now substitute the value of J in either original equation to solve for S:

3(17.99) + 2S = $81.61

53.97 + 2S = $81.61

2S = $81.61 - 53.97

2S = $27.64

Divide by 2 to solve for S:

S = $27.64 / 2 = $13.82

Therefore, the average cost of a movie ticket in Japan is $17.99 and in Switzerland is $13.82.

50 tiles

Step-by-step explanation:

The area of a square is the square of the side. The area of each tile is

a = (20 cm)^2 = 20 cm * 20 cm = 400 cm^2

Now we convert 2 square meters into square centimeters.

2 m^2 * (100 cm)/m * (100 cm)/m = 20,000 cm^2

2 m^2 = 20,000 cm^2

Now we divide the total area by the area of one tile.

(20,000 cm^2)/(400 cm^2) = 50
