Enter the following data into a graphing calculator. (5, 3) (7, 7) (12, 11) (-2, -3) (-1, 0) (5, 6) (-7, -2) (0, -2) What is the equation of the line of best fit? Round your answer to the nearest hundredth.

The graph of the equation x = -4 is shown in the image attached below.

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis) respectively.

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).

By critically observing the graph (see attachment), we can reasonably infer and logically deduce that the x-intercept is equal to -4.

Step-by-step explanation:

13a ^2+14-17a-12a ^2+12a+6a-a^ 2

=14-17a+12a+6a

=14+a    or     a+14

Answer:

Step-by-step explanation:

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

[tex]y-y_1=m(x-x_1)[/tex]

So, the equation for this problem, let

[tex](x_1,y_1)=(2,-1)[/tex]

then,

[tex]y-(-1)=m(x-2)\\y+1=m(x-2)[/tex]

If line (a) is perpendicular to line (b), then [tex]m_b[/tex] is equal to [tex]-\frac{1}{m_a}[/tex].  For this problem, let

[tex]m_a=-\frac{1}{2}[/tex] and [tex]m_b=2[/tex]

So,

[tex]y+1=(2)(x-2)\\y+1=2x-4\\(y+1)-1=(2x-4)-1\\y=2x-5[/tex]

The equation for capital gain as a percent of the original purchase price will be equal to a = (y - x)/x × 100.

If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.

The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. A mathematical operation like reduction, addition, multiplication, or division is used to include terms in an expression.

As per the given information in the question,

Use the equation for capital gain,

Let the selling price be y and the purchase price is x dollars.

Capital gain = Selling price - Purchase

Substitute the values,

Capital gain = y - x

Now, let's find out the percent increase.

Let's assume that 'a' is the percent increase.

So, the equation will be,

(a)(x) = y - x

ax = y - x

Divide both sides by x.

(ax)/x = (y - x)/x

a = (y - x)/x

Multiply the equation by 100 to show in percentage form,

a = (y - x)/x × 100

For the equation y=0, there is much less math involved. This is because, no matter what, for any value of x, y must always be equal to zero.

This is so because the y-intercept occurs at x = 0. X = 0, mx = 0, and Y = B at this point. When y = 0, we solve the equation for x to determine the x-intercept. The line crosses the x-axis at y=0,

You can mistakenly think of the line y = 0 as the y-axis, be aware of this. It's not right. Simply put, the line y=0 indicates that the y coordinate is always 0 for all locations (x, y) in the x-y plane, indicating that the line y=0 represents the x-axis.

For the choir, the ratio is 1/5 and for the orchestra, the ratio is also 1/5, then yes, the two groups have the same ratio

Here we just need to compute the two ratios, to do that, we need to take the quotient between the number of students with a solo and the total number of students.

For the choir, there are 25 students and 5 with a solo, so the ratio is:

5/25 = 1/5

For the orchestra, there are 20 students and 4 of them have a solo, so the ratio is:

The graph of the equation that is parallel to 4x – 3y = –12 is determined as: A. y = 4/3x - 3/2.

If two lines are parallel to each other, their graph will have the same slope value, m. This means if their equations are expressed as y = mx + b in slope-intercept form, they will both have the same value of m.

Given the equation of a graph as 4x - 3y = -12, rewrite it in slope-intercept form to determine the slope value:

4x - 3y = -12

-3y = -4x - 12

-3y/-3 = -4x/-3 - 12/-3

y = 4/3x + 4

This means the slope, m is 4/3. The slope of the graph that is parallel to it will also have a slope of 4/3.

The slope of y = 4/3x - 3/2 is also 4/3, therefore, the answer is: A. y = 4/3x - 3/2.

To find the perimeter of a triangle, we need to add up the lengths of all three sides. In this case, the sides of the triangle are given by the expressions 3x2 - y2, 4x2 - 7xy + 4y, and -3x + 7xy + 8y2.

To find the perimeter, we can simply add up these three expressions:

Perimeter = 3x2 - y2 + 4x2 - 7xy + 4y - 3x + 7xy + 8y2

= 7x2 - 3xy + 12y

This is the perimeter of the triangle. Note that the perimeter is a scalar quantity, not a vector, so it does not have a direction associated with it.

Answer:

k = -5

Step-by-step explanation:

The scalar product of vectors a and b is zero when the vectors are orthogonal (perpendicular):

[tex]\boxed{\begin{aligned}\vec a \cdot \vec b & = |a||b| \cos \theta\\& = |a||b| \cos 90^{\circ}\\& = 0 \end{aligned}}[/tex]

[tex]\textsf{Therefore, $\vec a$\; and \;$\vec b$\; are orthogonal when\; $\vec a\cdot \vec b=0$}[/tex]

Given:

Substitute the given vectors into the formula and solve for k:

[tex]\implies \langle 2, -2 \rangle \cdot \langle-5, k \rangle=0[/tex]

[tex]\implies (2)(-5) +(-2)(k)=0[/tex]

[tex]\implies -10-2k=0[/tex]
