Triangle a is a shape that is formed by connecting three points.

Triangle is a geometric figure with three sides and three angles. It is one of the basic shapes in geometry. Triangles are either right, acute, or obtuse, depending on the size of each angle. The sum of the angles in a triangle is 180 degrees. Triangles can be classified into equilateral, isosceles, and scalene triangles, depending on the length of the sides. All three types of triangles have various applications in mathematics, physics and engineering.

In order to reflect triangle a in the x axis, triangle b must be a mirror image of triangle a. To achieve this, each point in triangle a must be reflected across the x axis. This is done by multiplying the y coordinate of each point in triangle a by -1. As a result, triangle b will have the same three points as triangle a, except that the y coordinates of each point in triangle b will be the opposite of what they are in triangle a.

After reflecting triangle a in the x axis to form triangle b, the next step is to rotate triangle b around the origin 90°. This can be achieved by finding the coordinates of each point in triangle b, then rotating each point around the origin. To do this, the x coordinates of each point in triangle b remain the same, while the y coordinates are multiplied by -1. As a result, triangle c will be formed as a 90° rotation of triangle b around the origin.

The point that will be part of the linear regression line is (6,7).

The least-squares method is used to perform a linear regression on the given data points (6,7), (8,9), and (13,17). This method finds the line of best fit through the set of data points by minimizing the sum of the squares of the differences between the observed values and the predicted values from the line. To check whether a point is part of the regression line or not, we can substitute the x value of the point into the equation of the line and see if it gives the corresponding y value.

In this case, point (6,7) is part of the regression line because it satisfies the equation of the line.

Answer: The Midpoint of P and Q are (-0.5, -3.5)

Step-by-step explanation: To find the coordinates of the intersection points of the line and the curve, we can substitute the equation of the line into the equation of the curve and solve for x and y.

From the equation of the line: x - y = 3, we can see that y = x - 3

Substituting this into the equation of the curve:

3x^2 - (x-3)^2 + x(x-3) = 9

Now we can simplify and group

3x^2 - x^2 + 6x - 9 + x^2 - 3x = 9

3x^2 + 3x - 9 = 9

3x^2 + 3x = 18

3x(x+1) = 18

x(x+1) = 6

We can see that x = 2 and x = -3 are the solutions.

Substituting the x value back into the original equation of the line to find the y coordinate:

x = 2 => y = 2 - 3 => y = -1

x = -3 => y = -3 - 3 => y = -6

So the intersection points are (2,-1) and (-3,-6)

To find the midpoint of these two points, we take the average of their x and y coordinates:

x = (2 + -3) / 2 = -0.5

y = (-1 + -6) / 2 = -3.5

so the midpoint of the two intersection points is (-0.5, -3.5)

Answer:

Point, [tex](p,q)[/tex], is [tex](\frac{-1}{2} ,\frac{-7}{2} )[/tex].

Step-by-step explanation:

Given the equations  [tex]x-y=3[/tex]  and  [tex]3x^{2} -y^{2} +xy=9[/tex] . Find where they intersect and find the midpoint, [tex](p,q)[/tex], of the two intersection points. To find find points of intersection, you can either set up these equations as a system and solve algebraically or you can use a graphing calculator to graph the functions and see where they cross.

I will set up these equations as a system of equations,

[tex]\left \{ {{x-y=3} \atop {3x^{2} -y^{2} +xy=9}} \right.[/tex]

I will solve the top equation for [tex]x[/tex], and substitute it into the bottom.

[tex]x-y=3 = > x=3+y[/tex]

Now substitute [tex]x=3+y[/tex] for x into the bottom equation. Solve for y,

=> [tex]3x^{2} -y^{2} +xy=9[/tex]

=>[tex]3(3+y)^{2} -y^{2} +(3+y)y=9[/tex]

=> [tex]3(y^{2}+6y+9) -y^{2} +y^{2}+3y =9[/tex]

=>[tex]3y^{2}+18y+27 -y^{2} +y^{2}+3y =9[/tex]

=> [tex]3y^{2}+18y+27+3y =9[/tex]

=> [tex]3y^{2}+21y+27 =9[/tex]

=>[tex]\frac{3y^{2}+21y+27 =9}{3}[/tex]

=>[tex]y^{2}+7y+9 =3[/tex]

=>[tex]y^{2}+7y+6 =0[/tex]

=> [tex](y+1)(y+6)=0[/tex]

=>[tex]y=-1[/tex] or [tex]y=-6[/tex]

Now plug these values for [tex]y[/tex] into [tex]x=3+y[/tex].

When y=-1:

[tex]x=3+(-1)[/tex]

=> [tex]x=2[/tex]

When y=-6:

[tex]x=3+(-6)[/tex]

=> [tex]x=-3[/tex]

The solution to the system (points of intersection) is [tex](-3,-6)[/tex] and [tex](2,-1)[/tex]. I also attached a graph of the intersection points.

Now to find the midpoint of the two intersection points, [tex]midpoint=(\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )[/tex]

[tex](x_{1},y_{1}) = > (-3,-6)[/tex]

[tex](x_{2},y_{2}) = > (2,-1)[/tex]

=>[tex]midpoint=(\frac{-3+2}{2} ,\frac{-6+(-1)}{2} )[/tex]

=>[tex](\frac{-1}{2} ,\frac{-7}{2} )[/tex]

Thus, the point, [tex](p,q)[/tex], is [tex](\frac{-1}{2} ,\frac{-7}{2} )[/tex].

The inverse of f(x) = 2/3 x³ + 1 is f^-1(x) = (3/2)(x-1)^(1/3).

In other words, we can set y equal to the original equation and solve for x.

Let y = 2/3 x³ + 1

We can then subtract 1 from both sides to get y – 1 = 2/3 x³

We can then divide both sides by 2/3 to get (y – 1) • (3/2) = x³

Finally, we can take the cube root of both sides to get the inverse function:

x = (y – 1)¹/₃ • (3/2)¹/₃

Dividing 4x³ + x² - 27x + 18 by 4x - 3 will result to a quotient of x² + x - 6 and a remainder of 0

The long division method will require us to; divide, multiply, subtract, bring down the next number and repeat the process to end at zero or arrive at a remainder.

We shall divide the 4x³ + x² - 27x + 18 by 4x - 3 as follows;

4x³ divided by 4x equals x²

4x - 3 multiplied by x² equals 4x³ - 3x²

subtract 4x³ - 3x² from 4x³ + x² - 27x + 18 will result to 4x² - 27x + 18

4x² divided by 4x equals x

4x - 3 multiplied by x equals 4x² - 3x

subtract 4x² - 3x from 4x² - 27x + 18 will result to - 24x + 18

-24x divided by 4x equals -6

4x - 3 multiplied by -6 equals - 24x + 18

subtract - 24x + 18 from - 24x + 18 will result to a remainder of 0

Therefore by the long division method, 4x³ + x² - 27x + 18 by 4x - 3 gives a quotient x² + x - 6 and a remainder of 0.
