The solution to the equation 2-x³ = 4x + 3 is x=1.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

To find the solution to the equation 2-x³=4x+3, we can set the two sides of the equation equal to each other and solve for x.

2-x³ = 4x + 3

x³ - 4x - 1 = 0

To solve this equation, factor it or use the cubic formula.

One possible solution is x = 1, which can be verified by substituting it back into the original equation.

Another way to find the solution graphically, we can plot the graphs of y = 2-x^3 and y = 4x+3 on the same coordinate plane. The points at which the two graphs intersect are the solutions to the equation.

The graph of y = 2-x^3 is a downward facing parabola and the graph of y = 4x+3 is a line with slope 4 and y-intercept 3.

The intersection point of the parabola and the line is the solution x=1

It is not possible to find the other solutions graphically because the parabola doesn't intersect with the line again.

Therefore, the solution is obtained as x = 1.

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

                                                                    = 5.81

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.

What is the value at year 2. 5 and 5Let V0 be the initial value of the bulldozer, and k be the depreciation rate. We know that the value of the bulldozer after 2 years is V2 = V0 * e^(-k * 2) = 80000.

So, k = -ln(V2/V0) / 2.

The value of the bulldozer at year 2.5 can be calculated as:

V2.5 = V0 * e^(-k * 2.5)

The value of the bulldozer at year 5 can be calculated as:

V5 = V0 * e^(-k * 5)

Plugging in V0 = 125000 and k = -ln(V2/V0) / 2, we get:

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

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

We can start solving the problem using systems of equations. Let x be the cost of each balloon and y be the cost of each banner. We know from the problem that:

1x + 1y = 3 (the cost of 1 balloon and 1 banner is $3)

5x + 2y = 9 (the cost of 5 balloons and 2 banners is $9)

We can use the first equation to solve for one of the variables in terms of the other, and substitute that into the second equation. Then we can solve for the remaining variable.

From equation 1:

y = 3 - x

We can substitute this into equation 2:

5x + 2(3 - x) = 9

Which simplifies to:

5x + 6 - 2x = 9

3x = 3

x = 1

So each balloon costs $1

We can now substitute x=1 in the first equation:

1*1 + 1y = 3

y = 2

So each banner costs $2

Step-by-step explanation:

Let us assume the cost of

In first case , cost of 1 1 balloon and 1 banner is $3 . We can set up a equation as ,

1*x + 1*y = 3

x + y = 3 . . . . . (i)

In second case, cost of 5 balloons and 2 banners is $9 . So ,

5*x + 2*y = 9

5x + 2y = 9 . . . . . (ii)

From equation i and ii , we have ,

5(3-y) + 2y = 9

15 - 5y + 2y = 9

15 - 3y = 9

3y = 15 -9

3y = 6

y = 2

And we had ,

x + y = 3

x + 2 = 3

x = 3 - 2

x = 1

Hence,

and we are done!

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.

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?

After 30 cm of the belt sewn, Aspen will have equal numbers of green and silver beads left.

Aspen has 306 green beads and 210 silver beads.

For every 5 cm of a belt that Aspen sews, they use 40 green beads and 24 silver beads.

We can set up an equation to determine when Aspen will have equal numbers of green and silver beads left.

Let x be the number of centimeters of the belt Aspen will have sewn when they have equal numbers of green and silver beads left.

We can use the following equation:

306 - (40/5)x = 210 - (24/5)x

Solving for x, we get:

x = (306-210)/(40/5-24/5) = (96)/(16/5) = 96*5/16 = 30 cm
