(x'2-3x+5) dived (x-1)
The quotient of the division (x^2-3x+5) divided (x-1) is x - 2 with a remainder of 3
How to determine the quotientFrom the question, we have the following parameters that can be used in our computation:
(x^2-3x+5) divided (x-1)
Using the long division method of quotient, we have
x - 1 | x^2 - 3x + 5
The division steps are as follows
x - 2
x - 1 | x^2 - 3x + 5
x^2 - x
------------------------------------------------
-2x + 5
-2x + 2
------------------------------------------------
3
Hence, the quotient is x - 2

The value of y is directly proportional to the value of x. When x = 3.5, the value of y is 14.
What is the value of y when x = 28?
The value of y when x = 28 in the proportional relationship is 112.
How to find the value of y in the proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent.
The value of y is directly proportional to the value of x. When x = 3.5, the value of y is 14.
Therefore, let's find the constant of proportionality.
y = kx
14 = 3.5k
divide both sides by 3.5
k = 14 / 3.5
k = 4
Let's find the value of y when x = 28.
Hence,
y = 4x
y = 4 × 28
Therefore,
y = 112

Answer:
Step-by-step explanation: The formula for the line that intersects at (8,-5) and is parallel to line x+y = 8 is given by the algebraic expression y = -x +3.
What is Algebraic expression?
The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values.
Variables and constants can both be used in an algebraic expression.
A coefficient is any quantity that is added before a variable and then multiplied by it.
The Algebraic expression in this case is:
x + y = 8
which traverses points (8,-5)
Let's start by utilizing the point-intercept equation of line, which is provided by: to determine the slope of line m, that is parallel towards the line x + y = 8.
y = mx + c →(1)
x + y = 8
y = -x + 8
Comparing the aforementioned Algebraic expression to equation (1), we obtain
m = -1
The slope of the line parallel to the line x + y = 8 will now be the same, and it will be m = -1.
Let's use the point-slope equations of line to determine the linear equation now:
(y-y₁) = m(x-x₁)
Changing every value in the equation above to obtain the Algebraic expression for a line
(y-(-5)) = -1(x-8) (x-8)
(y+5) = -x+8
y + 5 = -x +8
y = -x +3
The formula for the line that intersects at (8,-5) and is parallel to line x+y = 8 is given by the algebraic expression y = -x +3

Step-by-step explanation:
The value of x can be solved as follows, take note of the numbers you will need to drag to complete the equations:
4x + 12x = 320 (segment addition postulate)
16x = 320 (combining like terms)
x = 20 (dividing both sides by 16)

A $659,000 property is depreciated for tax purposes by its owner with the straight-line depreciation method. The value of the building, y, after x months of use is given by
y = 659,000 − 1800x dollars.
After how many months will the value of the building be $450,200?
Answer:
116 months
Step-by-step explanation:
A $659,000 property is depreciated for tax purposes by its owner with the straight-line depreciation method. The value of the building, y, after x months of use is given by:
y = 659,000 − 1800x
After how many months will the value of the building be $450,200?
y = 659,000 − 1800x
450,200 = 659,000 − 1800x
subtract 659,000 from both sides:
450,200 - 659,000 = 659,000 − 1800x - 659,000
-208,800 = − 1800x
divide both sides by -1800:
-208,800/1800 = − 1800x/1800
116= x

What is the equation of a circle with a radius of 4 and a center located at (2,3)
Answer:
x² + y² - 4x - 6y - 3 = 0
Step-by-step explanation:
Formula for equation of circle when the radius r and centre (a,b) is given:
(x-a)² + (y-b)² = r²
(x-2)² + (y-3)² = 4²
Expanding the brackets;
x² - 4x + 4 + y² - 6x + 9 = 16
x² + y² - 4x - 6x + 4 + 9 = 16
x² + y² - 4x - 6x + 13 = 16
x² + y² - 4x - 6x + 13 - 16 = 0
x² + y² - 4x - 6x - 3 = 0 Ans.

Determine the graph that represents a function. On a coordinate plane, a circle is shown that crosses the x-axis at (negative 5, 0), the y-axis at (0, 5), the x-axis at (5, 0), and the y-axis at (0, negative 5). On a coordinate plane, a parabola opens to the left. It crosses the y-axis at (0, 3) and (0, negative 3), and the x-axis at (9, 0). On a coordinate plane, a straight line with a positive slope crosses the y-axis at (0, negative 2) and the x-axis at (1.2, 0).
Answer: The graph that represents a function is the parabola that opens to the left.
This can be determined by the following characteristics of the graph:
It is a parabola because it opens to the left and has a vertex on the y-axis.
It crosses the y-axis at (0, 3) and (0, negative 3), which means that it is symmetric about the y-axis, and also it crosses the x-axis at (9, 0) which means that it is a function.
A circle is not a function because, for any value of x, there are two different values of y that can be plotted on the graph (i.e. the point (5,0) and (-5,0) produce two different y values)
A straight line with a positive slope is not a function because, for any value of x, there is only one value of y that can be plotted on the graph.
So the parabola is the graph that represents a function.

What are composite functions?Composite functions are functions in which the input or argument are also functions.
The values of the composite functions based on the defined functions are found as follows;
f(x) = x² + 1, g(x) = -2·x + 5
Therefore; f(g(x)) is obtained by plugging in x = g(x) in f(x) as follows;
f(x) = x² + 1
f(g(x)) = (-2·x + 5)² + 1 = -2·x × (-2·x + 5) + 5 × (-2·x + 5) + 1
-2·x × (-2·x + 5) + 5 × (-2·x + 5) + 1 = 4·x² - 10·x - 10·x + 25 + 1
4·x² - 10·x - 10·x + 25 + 1 = 4·x² - 20·x + 26
When f(x) = x² + 1, and g(x) = -2·x + 5, f(g(x)) = 4·x² - 20·x + 26
g(f(x)) = is obtained by plugging in x = f(x) in g(x) as follows;
g(x) = -2·x + 5
f(x) = x² + 1
g(f(x)) = -2 × (x² + 1) + 5 = -2·x² - 2 + 5
g(f(x)) = -2·x² + 3
When f(x) = 2·x² - 2·x + 4, and g(x) = x + 3, we get;
f(g(x)) = 2×(x + 3)² - 2×(x + 3) + 4 = 2×(x² + 6·x + 9) - 2·x - 6 + 4
2×(x² + 6·x + 9) + 2·x + 6 + 4 = 2·x² + 10·x + 16
f(g(x)) = 2·x² + 10·x + 16
When f(x) = 2·x² - 2·x + 4, and g(x) = x + 3, f(g(x)) = 2·x² + 10·x + 16
g(f(x)) = is obtained by plugging in x = f(x) in g(x) as follows;
g(x) = x + 3
f(x) = 2·x² - 2·x + 4
g(f(x)) = 2·x² - 2·x + 4 + 3 = 2·x² - 2·x + 7
g(f(x)) = 2·x² - 2·x + 7
When f(x) = [tex]\sqrt{x - 4}[/tex], and g(x) = 2·x² + 4, we get;

Define angles.
An angled structure in geometry is composed of two rays that converge at the vertex, or core, of the angle. These rays are referred to as the angle's faces. Depending upon where they are situated, two beams may be able to form any angle within a plane. The intersection of two planes also produces an angle. Diahedral angles are the name for them. Light beams or lines that share the same endpoint in plane geometry can have a wide variety of shapes or angles. The English term "angle" derives from the Latin term "angulus," which meaning "horn." The intersection of the two rays is known as the vertex, or vertex of the angle.
Here,
QS cuts an angle. PQR, followed by ∠SQR = ∠ PQS and
∠PQS + ∠RQS = ∠PQR.
The equation then changes to
∠PQR = ∠PQS + ∠PQS
∠PQR = 2∠PQS
∠PQS equals ∠PQR/2
assuming∠ PQR = 119°
Replace in the resulting expression from the above;
∠PQS equals ∠PQR/2
∠PQS = 119/2
∠PQS = 59.5°
∠RQS is 59.5 degrees as ∠RQS = ∠PQR.
