The value of x when y is 32 is 21.3

From the question, we have the following parameters that can be used in our computation:

y varies directly as x

This means that

Y/X = y/x

From the question, we have the following values

x = 33 when y = 22

So, we have

33/22 = y/x

When x = 32, we have

33/22 = 32/x

Solve for x

x = 22 * 32/33

Samuel pay 5.81 for the 3 bottles of juice.

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

                                              = 6.5/100 × 5.46

                                              = 0.35

Thus, The actual amount of 3 bottles of juice = 5.46 + 0.35

a^6 + b^6= (a^2 +b^2)(a^4-a^2b^2+b^2) is an identity. The reasoning is done below.

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given an expression  a^6 + b^6= (a^2 +b^2)(a^4-a^2b^2+b^2) we need to assure if its right or not

Let "x" = a² and "y" = b² thus the equation

x³ + y ³ = ( x + y)(x² + y² - xy)

Take L.H.S.

=> x³ + y³ = (x + y)³ - 3xy (x + y)

» Take (x + y) common

=> (x + y) [(x + y)² - 3xy (1)]

=> (x + y) [(x² + 2xy + y²) - 3xy]

Because (a + b)² = a² + 2ab + b²

=> (x + y) (x² + y² + 2xy - 3xy)

=> (x + y) (x² + y² - xy)

L.H.S. = R.H.S.

Take R.H.S.

=> (x + y) (x² - xy + y²)

=> x(x² - xy + y²) + y(x² - xy + y²)

=> x³ - x²y +xy² + x²y - xy² + y³

=> x³ + y³

L.H.S. = R.H.S.

The complete question is given below.

Ivanna earns $2,400 if she doesn't sell any copies of history is fun.

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.

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.

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.

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

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).

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.

b) Using the above equation, after 25 days, Maya will have $35 left.

c) Using the above equation, after 9 days, Maya will have $83 left.

d) The slope is the average rate Maya spends per day, which is $3 while the y-intercept represents the initial amount she has.

A slope equation is written in the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Maya's average spending rate per day = $3

The number of days Maya has spent money = 14 days

The amount left after 14 days = $68

Let the initial amount Maya has = x and the number of days she has spent her money = n

a) x - 3n = 68

x = 68 + 3n

x = 68 + 3(14)

x = 68 + 42

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.
