Answer:
y - 4 = 4(x - 2)
Step-by-step explanation:
Please write these points as (2, 4) and (3, 8) (use commas and parentheses).
As we move from (2, 4) to (3, 8), x increases by 1 and y increases by 4. Thus, the slope is m = rise/run = 4/1 = 4
and the equation of the line through these two points (in point-slope form) is
y - 4 = 4(x - 2)
The slope of the line that passes through the point (2 4) and (3 8) is 4
The formula for calculating the equation of a line passing through the point (x1, y1) and (x2, y2) is expressed using the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given the coordinate points (2 4) and (3 8), the slope is expressed as:
[tex]m=\frac{8-4}{3-2}\\m=\frac{4}{1}\\m = 4[/tex]
Hence the slope of the line that passes through the point (2 4) and (3 8) is 4

Write a difference quotient that best approximates the instantaneous rate of change of g at x=0
Please show how you got your answer
We can define the average rate of change of a function f(x) in an interval [a, b] as:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:
a < x' < b
Such that a and b are really close to x'.
Then if we want to find the instantaneous rate of change of g at x = 0, we need to find values of a and b really close to zero.
Looking at the table, we can choose:
a = -0.001
b = 0.001
(are the two closer ones to zero)
Then the rate of change can be written as:
[tex]f(x) = \frac{g(0.001) - g(-0.001)}{0.001 - (-0.001)} = \frac{2.001 - 1.999}{0.002} = 1[/tex]
From that, we can conclude that a good approximation of the instantaneous rate of change is 1.

reggie pays 982.27 each month to rent an apartment. how much will it cost him to rent the apartment for two years
Answer:
982.27 = 1 month
12 months in one year
1 month x 12 is 12 months
982.27 x 12 = 11787.24
11787.24 x 2 = 23574.48
So, it is $23574.48

How should a random heterogeneous material be sampled in order to construct a representative sample?
Answer:
Explained below.
Step-by-step explanation:
Heterogeneous denotes to a form with different components or features, give the impression as uneven or varied.
A heterogeneous population or sample is the one where each and every individual has a diverse value for the distinctive characteristic one is interested in.
To select a representative sample from the random heterogeneous material one should divide the material into segments and then use random number, either by the random number table or by the random number generator, to select random segments of the material.

5) A data set with whole numbers has a low value 20 and high value of 82. Find the class width and class limits for a frequency table with 7 classes.
Answer:
Class width = 9
Class limits = 20 - 28; 20 - 28; 29 - 37; 38 - 46; 47 - 55; 56 - 64; 65 - 73; 74 - 82.
Step-by-step explanation:
We are given;
Highest value = 82
Lowest value = 20
Frequency = 7
Formula for class width is;
Class width = (Highest Value - Lowest Value)/number of classes
Class width = (82 - 20)/7
Class width = 8.8 ≈ 9
Now,since class width is 9, limits between 20 and 82 would be done at intervals of 9.
Thus;
Class limits = 20 - 28; 20 - 28; 29 - 37; 38 - 46; 47 - 55; 56 - 64; 65 - 73; 74 - 82.

there are twelve bottles in each box of bottled water. Write an equation representing the total number of bottles you get if you buy x boexes. use y to represent the total number of of bottles
Answer:
what does y and x represent no one can answer unless they have x and y
Step-by-step explanation:
Answer:
y=12x
Step-by-step explanation:
Since there are 12 bottles in each box, the total number is the number of boxes multiplied by 12.
For example, buying 1 box will give you 12 bottles (1x12) and buying 2 boxes would give you 24 (2x24).
Therefore the equation of the total number of bottles if you buy x boxes is:
y=12x

13/2 divided by 3/4
Answer: 26/3
Step-by-step explanation: When dividing by a fraction, we can change
the division sign to multiplication and flip the second fraction.
So 13/2 ÷ 3/4 means the same thing as 13/2 · 4/3.
So when dividing by a fraction, we can just multiply
by the reciprocal of that fraction or that fraction flipped.
Next we cross-cancel.
4 and 2 reduce to 2 and 1.
Multiplying across the numerator and denominators we have 26/3.

What is the solution to the equation 1/4x+2=-5/8-5
Answer: [tex]x=-61/2[/tex]
Simplify both sides of the equation
[tex]1/4x+2=(-5/8+-5)[/tex] (Combine Like Terms)
[tex]1/4x+2=-45/8[/tex]
Subtract 2 from both sides
[tex]1/4x+2-2=-45/8-2\\1/4x=-61/8[/tex]
Multiply both sides by 4
[tex]4*(1/4x)=4*(-61/8)\\x=-61/2[/tex]
