my question was why the general solution of the linear second order homogeneous equation is represented as combination of two particular solutions
The general solution of a linear second order homogeneous equation is represented as the combination of two particular solutions.
This is because the linear second order homogeneous equation is of the form ax2+bx+c=0 and has two distinct roots, i.e. x1 and x2. The general solution of the equation can be written as y=C1y1+C2y2, where C1 and C2 are constants and y1 and y2 are the two particular solutions. The particular solutions can be derived from the two distinct roots of the equation using the formula y1=e^(x1*t) and y2=e^(x2*t). The constants C1 and C2 can be found by solving the linear combination of the two particular solutions for the given initial conditions of the equation. This gives the general solution of the linear second order homogeneous equation as a combination of the two particular solutions.

A line passes through the point (-8, -9) and has a slope of Write an equation in slope-intercept form for this line.- 5/4
The equation in slope-intercept form for this line is y = -5/4x + 3.
What is the slope-intercept form of the line?
The slope-intercept form is a way of representing the equation of a straight line in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis). The slope of a line represents the steepness of the line, and the y-intercept represents the point at which the line crosses the y-axis.
A line can be represented by two points (x1, y1) and (x2, y2) the slope can be calculated by the formula:
m = (y2 - y1) / (x2 - x1)
In this case, the line passes through the point (-8, -9) and has a slope of -5/4, we can use the point-slope form of the equation of a line to find the equation of this line:
y - y1 = m(x - x1)
y - (-9) = (-5/4)(x + 8)
y = (-5/4)x + (-9) + (2*9)
y = (-5/4)x + 3
Hence, the equation in slope-intercept form for this line is y = -5/4x + 3.

If the ratio of profit shares is 3:7:9, then the total profit yield is 38000.
What is ratio?
Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
The share of Juma's profit is = 3
The share of Ali's profit is = 7
The share of Hassan's profit is = 9
The ratios can be written as 3x : 7x : 9x
The amount of money Juma received is = 6000
The equation for Juma's profit is -
3x = 6000
x = 6000/3
x = 2000
So, the value for Ali's profit -
7x = 7 × 2000
= 14000
The value for Hassan's profit -
9x = 9 × 2000
= 18000
Now, the total profit is represented by the equation -
= 3x + 7x + 9x
= 6000 + 14000 + 18000
= 38000
Therefore, the total profit is 38000.

Answer: The area of the floor can be found by multiplying the width and the length.
Area of the floor = (6x - 9)(6x + 9) = 36x^2 - 63x - 81
The area of each tile can be found by evaluating the expression 24x^2 - 12x - 36.
Area of each tile = 24x^2 - 12x - 36
To find out how many tiles are needed to cover the floor we need to divide the area of the floor by the area of each tile.
Number of tiles needed = (36x^2 - 63x - 81) / (24x^2 - 12x - 36)
The division is simplified by canceling out common factors between the numerator and denominator, the number of tiles is a fraction that can't be simplified any further.
So the answer is (36x^2 - 63x - 81) / (24x^2 - 12x - 36) tiles are needed to cover the floor.

y + 10 = 11y
Option (A) and (C) are correct.
What is a parallelogram?
A parallelogram is a four-sided shape with opposite sides that are parallel and congruent. In other words, opposite sides of a parallelogram are of equal length and parallel to each other. Additionally, opposite angles in a parallelogram are also congruent. It has two pairs of parallel sides. It can be thought of as a rectangle with opposite sides that are not necessarily at right angles to each other.
As the property of the parallelogram says
"Opposite sides of the parallelogram are equal"
So we can write
8x - 6 = 9x
y + 10 = 11y
Hence, The equations for the sides of the parallelogram would be
8x - 6 = 9x
y + 10 = 11y
Option (A) and (C) are correct.

given: pr is parralel to vo; ro is parralel to pv; pr is congruent to ro prove: angle 1 and angle 2 are complementary
According to the information ∠1 and ∠2 are complementary to each other.
∠1 ⊥ ∠2
Since PR is parallel to VO and RO is parallel to PV, it follows that PR is congruent to RO. This means that ∠1 and ∠2 are supplementary angles and thus, complementary.
Since PR // VO and RO // PV, then by the Transitive Property of Congruence, VO // PV.
Since PR ≅ RO and VO // PV, then by the Corresponding Angles Postulate, ∠1 ≅ ∠2.
Since ∠1 and ∠2 are congruent, then by the definition of complementary angles, ∠1 and ∠2 are complementary.
Thus, ∠1 and ∠2 are complementary.
∴ ∠1 and ∠2 are complementary
Congruent refers to something that is "absolutely equal" in terms of size and shape. The shapes hold true regardless of how we rotate, flip, or turn them. Draw two circles with the same radius, for instance, cut them out, and stack them on top of one another.

A bank representative studies compound interest, so she can better serve customers. She analyzes what happens when $2,000 earns interest at a rate of 4% for 3 years. Part a) Find the ending balance if it is compounded continuously. Part b) Find the interest earned if it is compounded continuously
The ending balance if the amount is compounded continusoly is $6,244.84
The interest earned is $4,244.84.
What is the ending balance and the interest?If an amount is compounded continuously, it means that both the amount invested and the interest earned increases in value infinitely over the investment period.
The formula for calculating future value when there is continuous compounding is : A x e^r x N
Where:
A= amount e = 2.7182818 N = number of years r = interest rateInterest = future value - amount invested
2000 x e^0.04 x 3 = $6,244.84
Interest = $6,244.84 - $2000 = $4,244.84

The value of x is 76°. The solution has been obtained using the properties of hexagon.
What is a hexagon?
A closed, two-dimensional, six-sided polygon in geometry is called a hexagon. It has six vertices, which together create six internal angles, and six line segments. The total of a hexagon's internal angles is 720°.
We know that sum of angles on a straight line is 180°.
So, on the first line with angle 60°, the other angle will be
180° - 60° = 120°
Similarly, on the second line with angle 64°, the other angle will be
180° - 64° = 116°
Similarly, on the third line with angle 36°, the other angle will be
180° - 36° = 144°
Similarly, on the fourth line with angle 48°, the other angle will be
180° - 48° = 132°
Similarly, on the fifth and sixth lines with angle x°, the other angles will be
180° - x° = (180-x)°
We know that sum of angles of interior angles of a hexagon is 720°
Therefore,
⇒ 120° + 116° + 144° + 132° + (180-x)° + (180-x)° = 720°
⇒ 512° + 180° - x° + 180° - x° = 720°
⇒ 872° - 2x° = 720°
⇒ 2x° = 152°
⇒ x = 76°
Hence, the value of x is 76°.
