What is the solution of 2x y is equal to 7?

A go-fuel kart's and maintenance costs are calculated as follows: c=10x+1200, where x is the number of rides. $40 is the cost per ride. it takes x = 40 to break even.

The cost function given here is

c(x) = 10x + 1200

Where x = number of rides

c(x) is the total cost including the fixed cost.

Also it is given that each ride costs $40

So Revenue function for x number of rides shall be

R(X) = 40x

For break even

the cost must be equal to the revenue

Hence

R(x) = C(x)

40x = 10x + 1200

Subtracting 10x from both sides we get

30x = 1200

Dividing by 30 on both sides

We get

x = 40

Answer:

0-a/c-0 = -a/c

Step-by-step explanation:

In the end, Moe played 51 games, while  Meeny played 17 games and Miny played 35 games.

We can start solving the problem by using algebra. Let x be the number of games Moe played. Then, since Meeny and Miny played 17 and 35 games respectively, the total number of games played is 17 + 35 + x = x + 52.

We know that in the second game and on, the one who sat out the preceding game would replace the loser of that game. Therefore, the number of games played by Moe is one less than the number of games played by Meeny and Miny combined.

x = (17 + 35) - 1 = 51.

So, Moe played 51 games.

The rate of change of function is {r} = (1/8)(B - A).

Given is a function f(x).

The given interval is - (2, 10). Since the table is not given, we can assume that -

f(10) = A

f(2) = B

Then, we can write the rate of change of functions as -

{r} = {f(b) - f(a)}/{b - a}

{r} = (B - A)/8

{r} = (1/8)(B - A)

A line segment whose endpoint are on the circle is called a __________ of a circle.

Chord

Radius

Tangent

Diameter

Answer: Chord

The equation of the tangent to the circle, whose equation is given below, at the point (0,4).

(x−2)² + (y−3)² = 5 is y = -x + 4

The equation of a circle is (x-a)^2 + (y-b)^2 = r^2, where (a,b) is the center of the circle, and r is the radius. So given equation is of circle whose center is (2,3) and radius is √(5)

To find the equation of the tangent to the circle at point (0,4) we have to find the slope of tangent and point of tangent.

The slope of tangent is equal to the derivative of the equation of the circle.

y = mx + c

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0, 4) and (x2, y2) = (2, 3)

so, m = (3-4) / (2-0) = -1

Now, we know the slope of the tangent line is -1, we can substitute this value in the point slope form of line equation,

y - y1 = m(x - x1)

y - 4 = -1(x - 0)

y = -x + 4

So, the equation of the tangent to the circle at the point (0,4) is y = -x + 4

Nico, Raj and Sandra are correct.

And the explanation is given.

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

An equation,

2/5(5 +x) = 8.

Nico, Aditi, Erick, Raj, and Sandra are solving the equation.

Approach 1:

Multiply by 5/2.

(5/2)(2/5)(5 +x) = 8(5/2)

5 + x = 20

x = 15.

Approach 2:

Multiply by 1/2 both sides

(1/2)(2/5)(5 +x) = 8(1/2)

5 + x = 4(5)

x = 15.

Approach 3:

Simplifying,

2 + 2/5x = 8

2x/5 = 6

x = 30/2

x = 15.

Answer:

Step-by-step explanation:here is a example:Recall that the volume of a regular prism is given by the area of the base times the height.

Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.

The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.

Recall that the are of a triangle is given by 1/2 base times height.

Thus the area of of the pentagon base of the prism is given by

Therefore, the volume of the prism is given by volume=7x(2x+1)=14x2+7x

The surface area that minimizes the weight of the storage bin is:

70x cm^2

To minimize the weight of an open-top storage bin in the shape of a rectangular prism, we need to minimize its surface area.

The volume of the storage bin is given as 3500 cm^3. Since the base of the bin is a square, we can let the length of one side of the base be x cm.

Therefore, the area of the base is x^2 cm^2.

          V = x^2 * h

where V is the volume and h is the height of the bin

So, we can substitute the value of V in the above equation to get:

3500 = x^2 * h

To minimize the surface area of the bin, we must minimize the sum of the areas of all its faces. The surface area of the rectangular prism is given by the formula:

           2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism respectively.

Since the base of the bin is a square, we can let the length and width be equal to x. Therefore, we can use the equation of the height of the bin and the formula of the surface area of the rectangular prism to get:

     2x^2 + 2xh = 2x^2 + 2x(3500/x^2)

Now, we can simplify the above equation to:

       2x^2 + 2x(3500/x^2) = 2x^2 + 70x

To minimize the surface area, we need to minimize the value of x. We can see that the second term of the equation is a linear function of x and has a negative slope, which means that as x increases, the surface area decreases. Therefore, the surface area will be minimized when x is at its maximum value.

   Therefore, the surface area that minimizes the weight of the storage bin is 70x cm^2.

The graphs of absolute value functions are called "V-shaped" or "V-graphs" because their graph is in the shape of a "V".

The graph of an absolute value function is a V-shape that opens upward or downward, depending on the function.

The vertex of the V is the point where the absolute value function equals zero. The two arms of the V extend out from this point, going in opposite directions along the number line.

The absolute value function is defined as |x| where x is any real number and |x| represents the distance of x from zero on the number line, i.e., always non-negative.

Example of an absolute function is f(x) = |x + 3|. The vertex is where

x + 3 = 0

That is at x = -3.

Here the function opens upward, but if the function was -|x + 3|, it will open downward.

Orthocenter: Solve system of 3 eqs. using 3 altitudes' equation & vertices' coordinates.

What is coordinate ?

Coordinate is a value or set of values that identify the position of a point in a certain space. Represented by ordered pair or triple of numbers (x,y) or (x,y,z) respectively.

The orthocenter of a triangle is the point where the three altitudes of the triangle intersect. To find the orthocenter of a triangle with coordinates, you can use the following steps:

1) Find the equation of the three altitudes of the triangle. To do this, you will need the coordinates of the three vertices of the triangle, as well as the slope of the line perpendicular to the side opposite each vertex.

2) Once you have the equations of the three altitudes, you can use them to find the coordinates of the orthocenter. To do this, you will need to solve a system of three equations with three variables (the x and y coordinates of the orthocenter, and the y-intercept of the altitude).

3) Once you have the coordinates of the orthocenter, you can use them to check your work by verifying that the point is indeed on each of the three altitudes.

Answer:

y = 5/2 x - 13

Step-by-step explanation:

A line perpendicular to y=-2/5x-1 has a slope equal to the negative reciprocal of -2/5. The slope of the line passing through (2,-8) can be calculated as follows:

m = -(-5/2) = 5/2

The equation of the line in point-slope form is:

y - (-8) = (5/2)(x - 2)

Expanding the equation gives:

y + 8 = 5/2 x - 5

Solving for y:

y = 5/2 x - 5 - 8

y = 5/2 x - 13

The equation of the line is:
