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.

Therefore, Nico, Raj and Sandra are correct.

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:

y = 5/2 x - 13

The equation of the line that has an undefined slope and passes through the point (4, 7) is y = 4.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know if a line has an undefined slope it is parallel to the y-axis and passes through the point (4, 7).

As it is parallel to the y-axis x-coordinate point remains the same.

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

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: a = 1, b = -11, and c = -42.

Step-by-step explanation:

The solutions to the equation x² - 11x - 42 = 0 are x = -6 and x = 7.

You can find the solutions by factoring the equation, or by using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a.

In this case, a = 1, b = -11, and c = -42.

The rate of change of a horizontal line is zero, this is because it does not rise vertically (i.e. y1 − y2 = 0).

A rate of change of a horizontal line is the same as its slope, which is the change in y over the change in x, or rise over run.

For the horizontal line that is shown in the graph below, the rate of change for this line is 0, and this can be confirmed by utilizing the slope calculation method.

This makes sense because the change in y of the line is zero, which means it it does not rise vertically (i.e. y1 − y2 = 0).

The ratio of the central angle measure to the circumference of a circle is called the "arc measure" and it is given by the formula:

arc measure = central angle measure / circumference

For a given central angle measure in degrees, the formula will be:

arc measure = (central angle measure in degrees) / 360

It's worth noting that this ratio is equal to the fraction of the circumference that the arc of the central angle measures.

For example, if the central angle measure is 90 degrees, the arc measure will be 90/360 = 1/4, meaning that the arc that is formed by the central angle measure is 1/4 of the circle's circumference.

It's also important to note that this ratio is also equal to the fraction of the total area of the circle that the sector formed by the central angle measures.

It's also worth noting that this ratio is always less than 1, since the central angle can't be greater than 360 degrees.

Therefore, The ratio of the central angle measure to the circumference of a circle is called the "arc measure" and it is given by the formula: arc measure = central angle measure / circumference

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
