Answer:
c=4.95+3.99b
Step-by-step explanation:
When there are no books, the service fee still applies, so when b=0, c=$4.95.
For each book downloaded $3.99 is added to the charge. The service fee is only charged once a month.
c=4.95+3.99b

I think it would have to be C because 20-13=7
What is the equation of the line that is parallel to y = 2/3x+ 4 and passes through
the point (-7, 1)?
Answer:
The answer is
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = ⅔x + 4
Comparing with the general equation above
Slope = 2/3
Since the lines are parallel their slope are also the same
Slope of parallel line = 2/3
Equation of the line using point (-7 , 1) and slope 2/3 is
[tex]y - 1 = \frac{2}{3} (x + 7) \\ y - 1 = \frac{2}{3} x + \frac{14}{3} \\ y = \frac{2}{3} x + \frac{14}{3} + 1[/tex]
We have the final answer as
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Hope this helps you

6/5(8k+2)=-36solve equation
Answer:
k=-4
Step-by-step explanation:
[tex]\frac{6}{5} (8*-4+2) = -36[/tex]
Answer:
k = -4
Step-by-step explanation:
6/5 (8k + 2) = -36
5 x 6/5 (8k + 2) = -36 x 5
6(8k + 2) = -180
48k + 12 = -180
48k = -180 - 12
48k = -192
48k/48 = -192/48
k = -4
1. Find two functions f(x) and g(x) such that f[g(x)] = x but g[f(x)] does not equal x.2. State the vertical, horizontal asymptotes and zeros of the rational function, f(x) = {x^2+3x+2}/{x^2+5x+4}.Why is there no zero at x = –1?3. Give an example and explain why a polynomial can have fewer x-intercepts than its number of roots.
Answer:
1. [tex]f(x)=x^{2}[/tex] and [tex]g(x)=-\sqrt{x}[/tex]
2. Vertical Asymptote: x=-4
Horizontal Asymptote: y=1
Zeros: (-2,0)
Because the graph will have a hole at x=-1. This is, the graph is not defined for that particular x-value.
3. [tex]f(x)=x^{2}+4[/tex]
It has two complex roots, so there is no place in the graph where it crosses the x-axis.
Step-by-step explanation:
1. If we find the composite function f[g(x)] with the functions:
[tex]f(x)=x^{2}[/tex] and g(x)=-x, we will get the following:
[tex]f[g(x)]=(-\sqrt{x})^{2}[/tex]
which simplifies to
f[g(x)]=x
on the other hand, if we find g[f(x)] we will get the following:
[tex]g[f(x)]=-\sqrt{x^2}[/tex]
which simplifies to:
g[f(x)]=-x
2.
Before finding the asymptotes, it's a good idea to factor both the numerator and denominator of the function, so we get:
[tex]f(x)=\frac{x^{2}+3x+2}{x^{2}+5x+4}[/tex]
[tex]f(x)=\frac{(x+2)(x+1)}{(x+4)(x+1)}[/tex]
we can now see that this function can be simplified. It is important to simplify this function so we don't confuse vertical asymptotes with holes in the graph, so when simplifying we get the following:
[tex]f(x)=\frac{x+2}{x+4}[/tex]
now we can set the denominator equal to zero.
x+4=0
and solve for x:
x=-4 this is our vertical asymptote.
For the horizontal asymptote, there is a rule that tells us that if the polynomials on the numerator and denominator have the same degree (the same greatest power), then the horizontal asymptote is found by dividing the lead coefficient of the polynomial on the numerator by the lead coefficient on the denominator. In this case the lead coefficients are 1 and 1 so the horizontal asymptote is:
[tex]y=\frac{1}{1}[/tex]
so the horizontal asymptote is at:
y=1.
The zeros of the function are located at the x-values that will turn the numerator of the simplified fraction equal to zero, so we get:
x+2=0
x=-2
so the only zero will be located at (-2,0)
x=-1 is not a zero because the original function is not defined for x=-1, there is a hole in the graph at this x-value.
Take a look at the graph of the function (See attached picture)
3.
This will happen when there are no real zeros. Take for example the function:
[tex]f(x)=x^{2}+4[/tex]
In this case this problem has 2 non-real zeros:
[tex]x^{2}+4=0[/tex]
[tex]x^{2}=-4[/tex]
[tex]x=\sqrt{-4}[/tex]
so:
x=2i or x=-2i
since they are complex numbers they cannot be graphed on a coordinate axis, so the graph will not cross the x-axis. See attached picture.

A question asks: How many hours per week do you watch television? The respondent can answer in minutes and/or hours. What would be the best numerical summary of data from 300 participants? A. Mean, standard deviation, and range B. Median, IQR, and range C. Number and percent of total for each response option D. A or B depending on the distribution of the sample E. B and C
Answer: D. A or B depending on the distribution of the sample
Step-by-step explanation:
Given: A question ask about how many hours per week do you watch television?
Total participants = 300
Since all participants are different , so have their own answer to this question in numerical terms.
We use proportion or percentage to summarize data if data is categorical, but here data is numerical (continuous).
here , we can use either mean or median ( if it has outliers).
For this we need to check the distribution of the data, if it is normal then Mean, standard deviation, and range would be a better option (as mean is the best measure of tendency)otherwise Median, IQR, and range would be a better option .
hence, the correct option is D. A or B depending on the distribution of the sample

help!! 2x - 8 + 3x - 12 = 60
Answer:
x=16
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x−8+3x−12=60
2x+−8+3x+−12=60
(2x+3x)+(−8+−12)=60(Combine Like Terms)
5x+−20=60
5x−20=60
Step 2: Add 20 to both sides.
5x−20+20=60+20
5x=80
Step 3: Divide both sides by 5.
5x
5
=80

What is the midpoint of A F?
Hey there! I'm happy to help!
A is -10 and F is -5. To find the number in between two numbers, you add them and divide by 2.
-10+(-5)=10-5=-15
-15/2=-7.5
So, the midpoint is -7.5, which is right in between C and D.

Answe

Step-by-step explanation:
I don’t know how to make a rule:(
Answer:
*assuming you know the concept of proportionality*
since L is directly proportional to T, an increase in L will result in an increase in T
so the solution of the first part is increases
in part 2, y is inversely proportional to x
which means that an increase in y will result in a decrease in x and vice-versa
So the answer of the second part is decreases
in part 3, since x is directly proportional to y, an increase in x will result in an increase in y
