The midpoint formula helps us to find the midpoint of a line given to us on a coordinate system.

The coordinate system in geometry is a plane space in which points are located using paired numerical values called coordinates. It is of two types Cartesian coordinate system and polar coordinate system

The cartesian coordinate system is further divided into majorly two parts i.e., 2-Dimensional and 3- dimensional systems. A 2-D system has 2 axis X and Y whereas a 3-D system has X, Y, and Z axes. The plane is divided into 4 quadrants

The midpoint formula is used to find the center of a line or a figure. It is a mathematical equation used in geometry and economics. On a line from point (x1,y1) to (x2,y2) the midpoint P= (x1+y1)/2 , (x2+y2)/2. It divides the line in a 1:1 ratio.

If the farmer plotted a straight line graph of how many goats he had left over time, the slope of the line would be -14.

To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:

Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.

In this case:

So the slope of the line is:

The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.

It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.

Answer: y = 8x

Step-by-step explanation:

The line passes through points (1,8) and (2,16).

Using this, we can first find the slope.

Slope = Δy/Δx = 8/1 = 8

So the slope is 8.

The equation is now

y = 8x + b

Let's use the point (1,8) to find the value of b now.

8 = 8 +b

b = 0

Therefore, y = 8x is the answer.

(you can skip the last step by noticing that the graph passes through the origin)

Answer:

y = 8x

Step-by-step explanation:

From inspection of the given graph, two points on the line are:

Substitute the points into the slope formula to find the slope of the line:

[tex]\implies m=\dfrac{16-0}{2-0}=\dfrac{16}{2}=8[/tex]

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

The y-intercept is the y-value of the point where the line crosses the y-axis. From inspection of the given graph, the y-intercept is zero. So b=0.

Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:

The solutions are:

(1,-4), and (-11,56)

Step-by-step explanation:

10 + y = 5x + x^2

5x + y = 1

Rearrange both equations to isolate y:

y = x^2 + 5x - 10

y = -5x+1

Since y=y, we set set the right sides of both equations equal to each other:

-5x+1 = x^2 + 5x - 10

Rearrange

-x^2 - 10x + 11 = 0

x^2 +10x - 11 = 0

Factor

(x+11)(x-1) = 0

x = -11 and 1

The quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

A quadratic equation in standard form is of the form ax² + bx + c, where a, b, and c are constants.

The axis of symmetry of a quadratic equation is given by the line x = -b/2a, so if the axis of symmetry is x=-2, we can set -b/2a = -2, which gives b = 4a.

To find the y-intercept of the quadratic equation, we can set x = 0 and substitute that into the equation: y = a(0)² + b(0) + c = c
So, if the y-intercept is (0,6) then c = 6.

By using above two information, we can write the quadratic equation in standard form as:

a(x+2)² + 4a(x+2) + 6 =0
=> a(x²+4x+4) + 6 = 0
=> a(x²+4x+4) = -6
=> a(x²+4x+4) = -6
=> x² + 4x + 4 = -6/a
=> x² + 4x + 4 = -6/a +10
=> x² + 4x - 6 = 0

So, the quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

The equation of the line given here is 2x + 3y = 12

Now rearranging it to the slope-intercept form we get

3y = -2x + 12

or, y = -2x/3 + 4

Now any 2 lines are perpendicular when the product of their slopes results in -1.

Hence, let the equation of the line perpendicular to the given line be

y = mx + c, where m is the slope of the line and c is the intercept.

Answer:

The following equations are equivalent:

x + (negative 4) = 7

Negative 5 + x = negative 2

All of these three equations are equivalent because they all represent the same mathematical relationship between x and other numbers. The variable x is the same in each equation. We can see this by applying the same operation on both sides of the equations, and the variable x will cancel out and the two sides will be equal.

We can perform a change of units to see that 280 square centimeters is equivalent to 0.028 square meters.

We want to perform a change of units between square centimeters and meters.

Answer:

Step-by-step explanation:

Mary is mistaken in her conclusion that the two triangles are not similar because size does not determine similarity. Similarity is determined by the proportionality of corresponding sides and the congruence of corresponding angles. Congruence is the equality of all the measures of the corresponding parts of two figures.

In order to determine if two triangles are similar, we must compare the ratios of corresponding sides. If the ratios of corresponding sides are equal, then the triangles are similar. In the diagram, it is not specified what the measures of the sides of the triangles are, so it is not possible to determine if the triangles are similar based on the information given. However, if the ratio of corresponding sides are same, then the triangles are similar.

It is important to note that similarity and congruence are different concepts. Congruence refers to the equality of all measures of corresponding parts of two figures, including side lengths and angles. Similarity refers to the proportionality of corresponding parts, including side lengths and angles. A triangle can be similar to another triangle without being congruent, and congruent triangles are always similar.

In summary, Mary is mistaken because the size of the triangle does not determine similarity, it is determined by the proportionality of corresponding sides and congruence of corresponding angles. Without knowing the measures of the sides of the triangles, it is impossible to determine if the triangles are similar based on the information given.

The probability that the 2 marbles taken from the bag are the same color is 25/49.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

The probability of taking two red marbles consecutively with replacement.
