Answer:
The y- intercept is -1,050 and the slope of the graph is 20.
Step-by-step explanation:
Consider the provided information.
The slope intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y intercept.
The production costs include a one-time cost for editing the book, which is $1,050.
We need to find the y-intercept, here the y-intercept is the one-time cost of editing the book.
As we want to plot a graph of the profit so the cost will represented as negative.
Therefore, b = -1,050
Hence, the y- intercept is -1,050.
Now again consider the provided information.
The company will market the book at a price of $35 but it is given that the cost of printing, is $15 per book.
Thus, the slope is the difference of the selling price and production cost.
Or we can say that the slope is the profit per book sold.
Slope = m = 35 - 15 = 20
Hence, the slope of the graph will be 20.
The required equation of the graph is y=20x-1050

Sarah converts the number 1,500,600 into scientific notation she writes 1.5006 x 10^4 which of the following statements is true?
A. Sarah is correct
B. Sarah is not correct because the exponent should be 6
C. Sarah is not correct because 1.5006 should be 1.5
D. Sarah is not correct because the exponent should be -4
Answer:
Option B. is the answer.
Step-by-step explanation:
Sarah converts the number 1500600 into scientific notation. She writes [tex]1.5006\times 10^{4}[/tex].
Therefore [tex]1.500600=1.5006\times 1000000=1.5006\times 10^{6}[/tex] is the correct representation.
Sarah should have written exponent as 6 in place of exponent 4.
Therefore Sarah is not correct.
Option B. is the correct option.

Given 3x <9 Choose the solution set
Answer:
[tex]x<3[/tex] or [tex](-\infty,3)[/tex]
Step-by-step explanation:
We have been given an inequality [tex]3x<9[/tex]. We are asked to find the solution set for our given inequality.
We will divide both sides of our inequality by 3 to solve for x.
[tex]\frac{3x}{3}<\frac{9}{3}[/tex]
[tex]x<3[/tex]
Therefore, the solution for our given inequality will be all values of x less than 3, that is [tex](-\infty,3)[/tex] in interval notation.

The first year, they found the chloride concentration changed by −135 mg/L . It is estimated that the chloride concentration will change −2115 mg/L the next year.
What is the total change that will likely occur in 2 years?
Enter your answer as a simplified mixed number in the box.
______mg/L
Answer:
The total change that will likely occur in 2 years is [tex]=-3\frac{2}{3}[/tex] mg/L
Step-by-step explanation:
Given : The first year, they found the chloride concentration changed by [tex]-1\frac{3}{5}[/tex] mg/L .
It is estimated that the chloride concentration will change [tex]-2\frac{1}{15}[/tex] mg/L the next year.
To find : What is the total change that will likely occur in 2 years?
Solution :
The chloride concentration changed by [tex]-1\frac{3}{5}=-\farc{8}{5}[/tex] mg/L in first year.
The chloride concentration will change [tex]-2\frac{1}{15}=-\frac{31}{15}[/tex] mg/L the next year.
The total change that will likely occur in 2 years is
[tex]=-\frac{8}{5}+(-\frac{31}{15})[/tex]
[tex]=\frac{-24-31}{15}[/tex]
[tex]=\frac{-55}{15}[/tex]

if g(x) = 2x-1 and h(x) = sqrt x find (g o h)(9)
Answer:
(g o h)(9) =5
Step-by-step explanation:
Given :[tex]g(x) = 2x-1[/tex]
[tex]h(x) = \sqrt{x}[/tex]
To Find: (g o h)(9)
Solution:
[tex]g(x) = 2x-1[/tex]
[tex]h(x) = \sqrt{x}[/tex]
To find (g o f)(x)=g(h(x))
[tex]g(h(x)) = 2\sqrt{x}-1[/tex]
Now substitute x = 9
[tex]g(h(9)) = 2\sqrt{9}-1[/tex]
[tex]g(h(9)) = 2(3)-1[/tex]
[tex]g(h(9)) = 6-1[/tex]
[tex]g(h(9)) = 5/tex]
(g o h)(9) =5
Hence the value of (g o h)(9) is 5

a chair is placed several feet from a fire in a fireplace the fireplace has a glass screen the side of the chair facing the fireplace gets warm because of conduction convection or radiation??? will give brainliest
The warmth felt by the chair facing the fireplace is primarily due to radiation, where heat from the fire emits infrared radiation that is subsequently absorbed by the chair surface.
Explanation:The side of the chair facing the fireplace gets warm primarily because of radiation. Radiation is the process whereby heat is transferred through electromagnetic waves. In this case, heat from the fire emits infrared radiation, which travels through the air until it strikes the surface of the chair and is absorbed, causing the chair to warm up.
In heat transfer, there are three main methods: conduction, convection, and radiation.
Conduction is the process whereby heat is transferred through direct contact of objects, while convection involves the movement of warm air or fluids. Conduction and convection play minor roles in this scenario -- conduction would occur if the chair were in contact with the warm air, and convection is mainly responsible for heat transfer within the air of the room.

in the figure below line DE is parallel to line FG and transversal AG
Answer: The answer is 147° and 33°.
Step-by-step explanation: We are given a figure in which the line DE is parallel to the line FG and AG is a tranversal. We are to find the value of 'x' and 'y' from the figure.
Also, given that
∠ABE = (5y - 18)°.
We can see from the figure that ∠DBG and ∠ABE are vertically opposite angles, so they must be equal.
That is,
[tex]\angle DBG=\angle ABE\\\\\Rightarrow x=5y-18\\\\\Rightarrow 5y-x=18.~~~~~~~~~~~~~~~(i)[/tex]
Also, since ∠DBG and ∠FGB are interior angles on the same side of the transversal, so their sum is 180°.
That is
[tex]\angle DBG+\angle FGB=180^\circ\\\\\Rightarrow x+y=180.~~~~~~~~~~~~~~~~~(ii)[/tex]
Adding equations (i) and (ii), we get
[tex]y+5y=18+180\\\\\Rightarrow 6y=198\\\\\Rightarrow y=33,[/tex]
and from equation (ii), we get
[tex]x=180-33=147.[/tex]
Thus, x° = 147° and y° = 33°.

Pedro buys 4 books at the fair for $7 each. Pedro hands the cashier 3 ten dollar bills. how much change would he receive? write an equation to solve. use c to represent the unknown.
The problem involves calculating the change received when Pedro buys four books at $7 each and pays with $30. The equation to solve this is c = $30 - $28. Therefore, Pedro receives $2 change.
Explanation:The subject of this question is a straightforward mathematics problem involving buying books and receiving change. We know that Pedro buys 4 books that each cost $7 and that he gives the cashier $30. To find out the change, represented as c , Pedro will get, we first figure out the total cost of the books: 4 books x $7 per book equals $28. Pedro pays with $30 so the calculation for the change would be: $30 (the amount Pedro paid) - $28 (the total cost of the books). This gives us the equation c = $30 - $28. Therefore, Pedro would receive $2 in change.

Pedro buys 4 books for $28 and pays with $30, so he would receive $2 in change. The equation to represent this is: c = $30 - $28.
To calculate the change Pedro receives, we can set up an equation where c represents the unknown change. Pedro buys 4 books at $7 each, so the total cost of the books is 4 books x $7/book = $28. He hands the cashier 3 ten dollar bills, which equals $30. The equation to find the change is then:
c = $30 - $28
Solving this equation, we get:
c = $2
So, Pedro would receive $2 in change after buying the books.
luisa sells stuffed animals. she sells a stuffed elephant for $34.90, and the sales tax is 6% of the sale price. about how much is the sales tax on the elephant?
To find the sales tax on a $34.90 item with a 6% tax rate, convert 6% to a decimal (0.06) and multiply by the item cost, resulting in a sales tax of about $2.09.
Luisa sells a stuffed elephant for $34.90 and needs to calculate the sales tax, which is 6% of the sale price. To find the sales tax, first convert the percent to a decimal by dividing by 100, which makes it 0.06. Then multiply the sale price by this decimal:
$34.90 x 0.06 = $2.094
Now, you need to round $2.094 to the nearest penny, which is $2.09. Therefore, the amount of sales tax on the stuffed elephant is approximately $2.09.
