Answer:

c) m = 5p-4

Explanation:

Given that function A is : x → +4 → ×2.

A(x) = 2(x+4).

Given that function B is: x → ÷5 → +1.

B(x) = x/5 + 1.

To find the working variables for:

m → Function A → Function B → 2p + 1.

Create this composite function: B(A(x)) = 2(x+4)/5 + 1

Then set x equal to m and solve for the working equation to 2p + 1

_______________

(simplify)

2(m+4)/5 + 1 = 2p + 1

-1 -1

________________

2(m+4)/5 = 2p

÷2 ÷2

___________

(m+4)/5 = p

×5 ×5

_________

(m+4) = 5p

-4 -4

________

m = 5p - 4

Find the value of k if it is known that the line y=kx+2 goes through point:

MrRissso [65]

Answer:

k = -10/7 and k = -3

Step-by-step explanation:

Given: y = kx + 2

where k is the slope of line and 2 is y-intercept.

∵ line y = kx + 2 is passing through point P (-7, 12), ∴ x = -7 and y = 12

Now substituting the value of x and y in above equation,

y = kx + 2

12 = k(-7) + 2

-7k = 12 - 2

- 7k = 10

$k = \frac{-10}{7}$

In the same way, ∵ line y = kx + 2 is passing through point P (3, -7), ∴ x = 3 and y = -7

y = kx + 2

Now substituting the value of x and y in above equation,

-7 = k(3) + 2

3k = -7 - 2

3k = - 9

k = -3

PLEASE HELP ASAP !! IF I DONT FINISH THIS HOMEWORK ILL GET GROUNDED .

Answer:

A) Histogram

Step-by-step explanation:

A) The first step would be to look at the purpose and use for each type of plotting method;

Dot Plot: Used to represent the distribution of data (for ex; #of Strawberries, Blueberries, and Raspberries.

Histogram: A histogram is used to summarize discrete or continuous data. In other words, it provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values

Box Plot: Summerizes a set of data measured on an interval scale.

Best choice: Histogram- The reason why a histogram is the best representation of the student quartiles is because a histogram is used to summarize discrete or continuous data, and the given data is discrete

To create your histogram you first have to create a frequency table like the one below;

On the vertical axis, place frequencies. Label this axis "Frequency".

On the horizontal axis, place the lower value of each interval. Label this axis with the type of data shown (Score, etc.)

Draw a bar extending from the lower value of each interval to the lower value of the next interval. The height of each bar should be equal to the frequency of its corresponding interval.

That's how it's done!
