Given the two points (-12, 18) and ( 24, -54) what is the slope?

Answers

Answer:

Slope = -2

Step-by-step explanation:

Use the equation to find a slope:

y2-y1/x2-x1 = slope

-54 - 18 = -72

24 - (-12) = 36

-72/36= -2

A. [tex]\frac{1}{25}[/tex] dollars per day; the cost is $25 for each day.

B. [tex]\frac{75}{1}[/tex] dollars per day; the cost is $75 for each day.

C. [tex]\frac{25}{1}[/tex] dollars per day; the cost is $25 for each day.

D. [tex]\frac{1}{150}[/tex] dollars per day; the costs $1 for 150 days

Answers

Answer:  C. (25)/(1) dollars per day; the cost is $25 for each day.

$25/ 1 day or $25 a day

Step-by-step explanation:

Answer:

The rate of change is 25. It means the cost increased by $25 per day.

Step-by-step explanation:

The given table is

Time (days)       Cost ($)

      3                   75

      4                  100

      5                  125

      6                  150

It means the graph of this constant function passing through the points (3,75) and (4,100).

If a line passing through two points, then the slope of the line is

Therefore the rate of change is 25. It means the cost increased by $25 per day.

Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal count of everyone in the U.S. every 10 years and has provided the following data that gives the median age of an American man at the time of his first marriage.


What does it mean in this situation if the average rate of change is negative?
a.
It means that the median age of a man at the time of his first marriage is increasing.
b.
It means that the median age of a man at the time of his first marriage is decreasing.
c.
It means that the median age of a man at the time of his first marriage has a constant rate of change.
d.
There is no way to determine the average rate of change in this situation.

The Answer is D

Answers

Answer:

If the average rate of change in the data is negative, based on the variables analyzed;

b. It means that the median age of a man at the time of his first marriage is decreasing

Step-by-step explanation:

The given data is presented as follows;

Year;        [tex]{}[/tex]       1910, 1920, 1930, 1940, 1950, 960, 1970, 1980, 1990, 2000

Median Age; [tex]{}[/tex] 25.1,   24.6, 24.3,  24.3,  22.8, 22.8, 23.2, 24.7, 26.1,   26.8

The date points are plotted on a graph using Microsoft Excel

[tex]The \ average \ rate \ of \ change = \dfrac{The \ change \ in \ the \ median \ age}{The \ corresponding \ change \ in \ years \ (always \ +ve)}[/tex]The corresponding change in years, Δx, is positive because, we have;

Δx = x₂ - x₁ = Higher year - Previous year

Therefore, for a negative average rate of change, we have;

[tex]The \ average \ rate \ of \ change = -ve = \dfrac{The \ change \ in \ the \ median \ age}{+ve}[/tex]

∴ The change in the median age, Δy = +ve × (-ve) = -ve (negative)

Δy = -ve

∴ Δy = Median age for higher year - Median age for previous year = -ve

Median age for higher year = -(y) + Median age for previous year

Where 'y' is positive  

∴ Median age for subsequent year < Median age for previous year

Therefore, if the average rate of change is negative, the median age of a man's first marriage is decreasing

Answers

Answer:

[tex]\frac{19}{40}[/tex]

Step-by-step explanation:

The computation of the meters of cloth that were not use is shown below:

= Used for making a curtain - purchase of curtain cloth

[tex]= \frac{3}{5} - \frac{1}{8}\\\\= \frac{24 - 5}{40} \\\\= \frac{19}{40}[/tex]

Hence, the meters of cloth that was not used is [tex]\frac{19}{40}[/tex]

A number when divided by 5 gives 0 as remainder, that number when divided by 7 gives 0 as remainder also. What will be the remainder when that number is divided by 35?

Answers

Answer:

zero

Step-by-step explanation:

The computation of the remainder when the number would be divided by 35

Let the number be x

So if x is divided by 5 gives the remainder 0

x = 0

And, if x is divided by 7 gives the remainder 0

x = 0

So if x is divided by 35 so the remainder is also zero
