Ivanna earns $2,400 if she doesn't sell any copies of history is fun.
What is the difference between positive and negative number?Ivanna makes an extra $120 ($120) for each additional copy she sells and a loss of $120 ($120) for each fewer copy.
If Ivanna doesn't sell any copies of History is Fun, her total compensation is $2,400.
Ivanna makes a total salary of y = 2,400 + 120x, where x is the quantity of copies of her book History is Fun she sells.
We compare the compensation for two successive values of y to determine the change in Ivanna's pay.
We must estimate y when x exists of consecutive values i.e. 1, 2, 3, 4
We compute the value of y when x = 1, 2 and 3.
When x = 1, y = 2,400 + 120 (1) = 2,400 + 120 = $2,520.
When x = 2, y = 2,400 + 120 (2) = 2,400 + 240 = $2,640.
When x = 3, y = 2,400 + 120 (3) = 2,400 + 360 = $2,760.
To estimate the increase in her pay for a copy, we subtract y when x = 2 from y when x = 3.
(y when x = 3) - (y when x = 2) = $2,760 - $2,640 = $120.
So for every extra copy, Ivanna gets an extra $120.
To estimate the decrease in her pay for a copy, we subtract y when x = 3 from y when x = 2.
(y when x = 2) - (y when x = 3) = $2,640 - $2,760 = -$120.
So for every less copy, Ivanna loses $120.
To estimate her pay when she doesn't sell any copies of history is fun, we substitute the value of x as 0 in y.
When x = 0, y = 2,400 + 120 (0) = $2,400.
So Ivanna earns $2,400 if she doesn't sell any copies of history is fun.
The complete question is:
Ivanna is a software saleswoman. Let y represent her total pay (in dollars). Let x represent the number of copies of History is Fun she sells. Suppose that x and y are related by the equation 2400+120x = y.
Answer the questions below.
Note that a change can be an increase or a decrease.
For an increase, use a positive number. For a decrease, use a negative number.
What is the change in Ivanna's total pay for each copy of History is Fun she sells?
What is Ivanna's total pay if she doesn't sell any copies of History is Fun?

When the function f(x) is divided by 3x + 1, the quotient is 2x^2 + 2x - 9 and the remainder is 7. Find the function f(x) and write the result in standard
form.
Answer:
To find the function f(x), we need to use the Remainder Theorem. The Remainder Theorem states that if we divide a polynomial by x - a, the remainder will be equal to the value of the polynomial at x = a.
We know that f(x) divided by 3x + 1 leaves a remainder of 7, so we can set up the equation:
f(x) = (3x + 1)(2x^2 + 2x - 9) + 7
Expanding the left side of the equation, we get:
f(x) = 6x^3 + 2x^2 - 27x - 9 + 7
Simplifying, we get:
f(x) = 6x^3 + 2x^2 - 27x + 2
The function f(x) is in standard form.

The Pythagorean Theorem states that the square of the lengths of the two sides of a right triangle adds to the square of the length of the hypotenuse.
How do you prove Pythagorean triples?The Pythagorean Theorem states that a ² +b ² =c ² for a right-angled triangle ABC, right-angled at B. The whole integers a, b, and c form a Pythagorean triple if a and b are the lengths of the two sides of a right-angled triangle with hypotenuse c.
Draw a BD that is perpendicular to AC and meets at D. So, the Pythagorean theorem is established. Recall that the Pythagorean Theorem only applies to right-angled triangles. Two even numbers and one odd number, or all odd numbers, cannot form a Pythagorean triple. The square of an odd number is an odd number, and the square of an even number is an even number, hence this is true. A, B, and C are the three positive integers, and the Pythagorean triples are written as a ² +b ² =c ².

Graph the function.
f(x)=-2x²
Plot five points on the graph of the function: one point with x=0, two points with negative x-values, and two points with positive x-values.
Answer: The graph of the function f(x) = -2x² is a parabola that opens downward, with its vertex at the origin (0,0). The x-axis is the axis of symmetry for this parabola.
To plot five points on the graph of the function, we can substitute different x-values into the function and solve for y:
For x = 0, y = f(0) = -2(0)² = 0
For x = -2, y = f(-2) = -2(-2)² = 8
For x = -3, y = f(-3) = -2(-3)² = 18
For x = 2, y = f(2) = -2(2)² = -8
For x = 1, y = f(1) = -2(1)² = -2
So, the five points on the graph of the function are (0,0), (-2,8), (-3,18), (2,-8), (1,-2).
It's important to note that, the graph of f(x)=-2x² will be a parabola opening downward and passing through the points that we found.

Samuel pay 5.81 for the 3 bottles of juice.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Samuel buys 3 bottles of juice that each have an original price of 2.80.
And, He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%.
Here, The original cost of 3 bottles of juice = 3 × 2.80
= 8.40
Now, He uses a coupon for 35% off.
Hence, The off price = 35% of 8.40
= 35/100 × 8.40
= 2.94
So, The amount of 3 bottles of juice = 8.40 - 2.94
= 5.46
And, He is changed sales tax at a rate of 6.5%.
Thus, The sales tax on bottles = 6.5% of 5.46

For the given graph, the slope is 2/9, t the U.S. box office revenue in 2018 is 12 billion.
Given a graph depicting approximations of US box office earnings (in billions of dollars) from 2000 to 2012, what would you conclude?
We must calculate the graph's slope and y-intercept.
In order to overcome the issue, we are employing the point-slope form. Two points are obtained from the graph: (x1,y1) = (0,8) and (x2,y2) = (9, 10).
Consequently, slope is m = y2 - y1 / x2 - x1
⇒ 10 - 8/ 9 - 0 = 2/9
This is the graph's straight line's slope.
The point-slope form is given by y-y1 = m. (x-x1)
Meaning: y - 8 = m(x - 0)
The line's equation is then y = 2x/9 + 8, with 8 serving as the y-intercept.
• In this case, the y-intercept provides the beginning value, or 8 when x = 0. Here, the year 2000 is represented by the number 0, and the U.S. box office took in $8 billion in that year.
2 • The graph's straight line shape and slope (m) indicate that the U.S. box office's revenue is rising at a steady rate of $2 billion every two years. 2 year 9 is on the x-axis.
• Using the equation, y = 2, we may get the precise income in any year from 2000 through 2012.
The x axis in the graph corresponds to the year;
hence, the point at x = 0 denotes the year 2000 and the one at x = 12 denotes the year 2012.
In order to get the income for 2018, we must determine the value of y when x equals 18.
The formula is y = 2x/9 + 8
y = 2(18)/9 + 8
y = 12
That is, 12 billion dollars will be made at the U.S. box office in 2018.

(14cos45° + 70cos180°, 14sin45° + 70sin180°) = (17.9, -55.1) is the component form of the sum of u and v with direction angles u and v.
What's an angle?The amount of rotation that occurs between two planes or straight lines is what is meant to be meant by the geometrical term "angle." A full circle is 360 degrees, and an angle is measured in degrees. Right angles (90 degrees), acute angles (less than 90 degrees), and obtuse angles (more than 90 degrees) are the most prevalent types of angles. Depending on how they relate to one another, angles can also be broken down into complementary or supplementary categories. The sum of complementary and supplementary angles is 90 degrees, while the sum of the two is 180 degrees.
Component form :The vector addition formula can be used to determine the component form of the sum of u and v. According to this formula, the direction angle of the vector sum is equal to the arctangent of the ratio of the sum of the y-components of the two vectors to the sum of the x-components of the two vectors, while the magnitude of the vector sum of two vectors is equal to the square root of the sum of the squares of each vector's magnitude.
The component form of the sum of the given vectors u and v is as follows:
Magnitude = √(14²) + (70²)) = 70.45

C = G - 3F ______(1)
F = 2x² + 6x - 5
G = 3x² + 4
Substituting F and G in (1)
C = 3x² + 4 - 3(2x² + 6x - 5)
C = 3x² + 4 - 6x² - 18x + 15
C = -3x² - 18x + 19
Thus,
The trinomial expression is
C = -3x² - 18x + 19

A team of 9 dodgeball players needs to choose
The function that would be needed for the team of dodgeball players to choose a co - captain and a captain would be a permutation.
When is a permutation needed ?The techniques used to determine how many outcomes are conceivable in certain circumstances are permutation and combination. Combinations and permutations are referred to as selections and arrangements, respectively. The sum rules and product rules, which are based on the basic concept of counting, make counting simple to use.
When an order or sequence of arrangement is required, permutations are used. There is an order that needs to be used here and that order is that a captain is picked to have more authority than a captain.

if two distinct members of the set $\{ 2, 4, 12, 14, 21, 28, 98 \}$ are randomly selected and multiplied, what is the probability that the product is a multiple of 196? express your answer as a common fraction.
The probability that the numbers are selected and multiplied to be a multiple of 196 is 1/3.
196 is the multiple we require.We list the components of 196, which are 14*14=2*7*2*7.
Therefore, the required numbers that will be present in any product must have at least these as its factors.So, we choose 98 now, and it's possible that all it takes to achieve 196 is to multiply that by 2. Therefore, if we take 98 as one of our numbers, the other numbers that must be multiplied are 2,4,12,14,28. That makes 5 pairs necessary.
So, we choose 98 now, and it's possible that all it takes to achieve 196 is to multiply that by 2. Therefore, if we take 98 as one of our numbers, the other numbers that must be multiplied are 2,4,12,14,28. That makes 5 pairs necessary. We can now take pairings like (21,28) and (14,28) based on the prime factorization (14,28).
The total number of possible pairs is ⁷C₂ = 21
Therefore, the required probability =7/21=1/3

We also know that 1 4 and 8 5 by the vertical angles theorem.
Vertical angles, also known as vertically opposite angles, are the opposing angles formed when two lines converge. Angles that are vertically opposite one another are always equal to one another. A vertical angle and the angle it is near to are also supplementary angles, which means their combined angle is 180 degrees.
The opposite angle, for example, is 45° when two lines intersect to form an angle, say X=45°. And the angle next to angle X will be 180 – 45, or 135 degrees.
