The general solution is [tex]$$\begin{pmatrix}x \\ y\end{pmatrix} = c_1e^{(7+\sqrt{3})t}\begin{pmatrix}5 \\ 1+\sqrt{3}\end{pmatrix} + c_2e^{(7-\sqrt{3})t}\begin{pmatrix}5 \\ 1-\sqrt{3}\end{pmatrix}$$[/tex]
How to find the general solution of the given system?We can write the system of differential equations in matrix form as:
[tex]\frac{d}{dt}\begin{pmatrix}x \\ y\end{pmatrix} = \begin{pmatrix}6 & -5 \\ -2 & 8\end{pmatrix}\begin{pmatrix}x \\ y\end{pmatrix}[/tex]
To find the general solution, we first need to find the eigenvalues and eigenvectors of the coefficient matrix:
[tex]$$\begin{pmatrix}6-\lambda & -5 \\ -2 & 8-\lambda\end{pmatrix} = 0$$[/tex]
Solving the determinant, we get:
[tex]$$(6-\lambda)(8-\lambda) - (-2)(-5) = 0$$[/tex]
Simplifying, we get [tex]$\lambda^2 - 14\lambda + 46 = 0$[/tex]. Using the quadratic formula, we get:
[tex]$$\lambda = \frac{14 \pm \sqrt{(-14)^2 - 4(1)(46)}}{2} = 7 \pm \sqrt{3}$$[/tex]
Thus, the eigenvalues are [tex]\lambda_1 = 7 + \sqrt{3}$ and $\lambda_2 = 7 - \sqrt{3}[/tex]
To find the eigenvectors, we solve the system of equations[tex]$(A - \lambda I)\mathbf{v} = \mathbf{0}$[/tex] for each eigenvalue. For[tex]$\lambda_1 = 7 + \sqrt{3}$[/tex], we have:
[tex]$$\begin{pmatrix}-1-\sqrt{3} & -5 \\ -2 & 1-\sqrt{3}\end{pmatrix}\begin{pmatrix}v_1 \\ v_2\end{pmatrix} = \begin{pmatrix}0 \\ 0\end{pmatrix}$$[/tex]
Solving this system, we get the eigenvector [tex]$\mathbf{v}_1 = \begin{pmatrix}5 \\ 1+\sqrt{3}\end{pmatrix}$[/tex].
Similarly, for [tex]$\lambda_2 = 7 - \sqrt{3}$[/tex], we have:
[tex]$$\begin{pmatrix}-1+\sqrt{3} & -5 \\ -2 & 1+\sqrt{3}\end{pmatrix}\begin{pmatrix}v_1 \\ v_2\end{pmatrix} = \begin{pmatrix}0 \\ 0\end{pmatrix}$$[/tex]
Solving this system, we get the eigenvector[tex]$\mathbf{v}_2 = \begin{pmatrix}5 \\ 1-\sqrt{3}\end{pmatrix}$.[/tex]
Therefore, the general solution is:
[tex]$$\begin{pmatrix}x \\ y\end{pmatrix} = c_1e^{(7+\sqrt{3})t}\begin{pmatrix}5 \\ 1+\sqrt{3}\end{pmatrix} + c_2e^{(7-\sqrt{3})t}\begin{pmatrix}5 \\ 1-\sqrt{3}\end{pmatrix}$$[/tex]
where [tex]$c_1$[/tex] and [tex]$c_2$[/tex] are constants determined by the initial conditions.

Solve for x and find DFG
Since FE bisects <DFG, then the value of x and measure of <DFG are:
a. x = 24
b. m<DFG = 106^o
What is an angle bisector?An angle bisector is a straight line constructed in such a way that it divides a given angle into two equal measures.
Thus given that FE bisects <DFG, this implies that;
i. m<DFE ≅ m<EFG
So that,
3x - 19 = 2x + 5
collect like terms to have;
3x - 2x = 19 + 5
x = 24
To solve for x, the value of x is 24^o.
ii. To determine the measure of DFG;
m<DFG = (3x - 19) + (2x + 5)
= (3(24) - 19) + (2(24) + 5)
= 53 + 53
= 106
m<DFG = 106^o

A graph of the line with slope -3 passing through the point (4, -1) has been plotted in the image attached below.
What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.From the information provided above, we have the following slope and data points on the line:
Points = (4, -1).Slope, m = -3At point (4, -1), a linear equation of this line can be calculated in point-slope form as follows:
y - y₁ = m(x - x₁)
y - (-1) = -3(x - 4)
y + 1 = -3x + 12
y = -3x + 12 - 1

The total measure of the angles is (n−2)·180°, where n=8. The term regular means all interior angle measures are the same. How can you determine each angle measure from the total angle measure?
Each measure of the angle when the total measure of the angles is (n−2)·180° and n is 8 will be 235°.
How to calculate the angle?From the information, the total measure of the angles is (n−2)·180°, where n=8. The term regular means all interior angle measures are the same.
It should be noted that in Mathematics, the value of the sum of angles is Illustrated in this case. We can determine each angle measure from the total angle measure thus:
(n - 2) × 180
n = 8
It should be noted that n in this case simply means the number of sides
= (n - 2) × 180
= (8 - 2) × 180
= 1080°
Each measure of the angle will be:
= 1080° / 8

Mrs. Tenon buys 25 party favors for $5. Find the constant ofproportionality?Mrs. Tenon has spent $5 on 25 party favours.
Equation form of proportional relationships is written as y=kx.
If you substitute $5 for y and $25 for x in the formula for the proportional relationship above, you can find the value of the proportionality constant, or k.
$5=k(25)\sk=$5/25\s=0.2
0.2 is the proportionality constant. Thus, each party favour costs $0.20.
Let's say there are r party favours and the cost is c. c=0.2r
In the equation above, 40 should be substituted for r to get the price of 40 party favours: c=0.2 (60) = 12.00.

Que knows that the required hypotenuse of the given right triangle is 18.35 units from the Pythagorean theorem.
What is the Pythagorean theorem?To determine the undiscovered side of a right-angled triangle, utilize the Pythagoras theorem.
The hypotenuse (third side) of a right-angled triangle, for instance, can be determined using the formula c2 = a2 + b2, where 'c' stands for the hypotenuse and 'a' and 'b' are the two legs.
So, we have:
Height of 6 and bas of 9 units of the right triangle.
Pythagorean formula:
c=√a²+b²
Now, insert values and calculate as follows:
c = √a²+b²
c = √9²+16²
