calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 9, 31) and (x₂, y₂ ) = (15, - 41) ← 2 ordered pairs from the table
m = [tex]\frac{-41-31}{15-(-9)}[/tex] = [tex]\frac{-72}{15+9}[/tex] = [tex]\frac{-72}{24}[/tex] = - 3
the y- intercept is the value of g(x) when x = 0 , then from the table
y- intercept = 4
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then equation is
y = - 3x + 4

BC = 8, AC = 3x - 8 and AB = 2x - 7
The length of AC and AB is 19 and 11.
What is length?It is the measurement of something from end to end or along its longest side or a measurement of a particular part of something:
We have,
BC = 8
AC = 3x - 8
AB = 2x - 7
We can make the line as:
A______B______C
We can write as:
AC = AB + BC
3x - 8 = 2x - 7 + 8
Simplify all the like terms together.
3x - 2x = 8 - 7 + 8
x = 16 - 7
x = 9
Now,
AC = 3x - 8 = 3 x 9 - 8 = 27 - 8 = 19
AB = 2x - 7 = 2 x 9 - 7 = 18 - 7 = 11
Thus the length of AC and AB is 19 and 11.

The factorization of the given expression 3(a-b)(3r-T)+9(b-a)(2t-5s) will be equal to 3(a-b){[3r-T]-392t-5s]}.
What is an expression?Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Given expression is 3(a-b)(3r-T)+9(b-a)(2t-5s) the factorization will be done as below:-
E = 3(a-b)(3r-T)+9(b-a)(2t-5s)
E = 3(a-b)(3r-T)- 9(a-b)(2t-5s)
E = 3(a-b){[3r-T]-392t-5s]}.

g(n)=-4n-4
h(n)=n² +5+n
Find (g • h)(n)
The equation of the (g • h)(n) is (g • h)(n) = -4n³ - 8n² - 24n - 20 if the g(n)=-4n- 4 and h(n)=n² +5+n.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
g(n) = -4n - 4
h(n) = n² +5+n
(g • h)(n) = g(n)h(n)
= (-4n - 4)(n² +5+n)
= -(4n + 4)(n² +5+n)
After simplification:
(g • h)(n) = -4n³ - 8n² - 24n - 20
Thus, the equation of the (g • h)(n) is (g • h)(n) = -4n³ - 8n² - 24n - 20 if the g(n)=-4n- 4 and h(n)=n² +5+n.

Question: 18 The auditorium at McCaskey East High School in Lancaster, PA has 800 seats. Suppose that the drama club has a goal of making $3400 each night of their spring play to cover expenses and raise money for the club. Adult tickets are $7 and students/senior tickets are $4.
Based on the information, it should be noted that there be 67 adults and 733 students in the auditorium.
How to calculate the value?Let adults tickets = a
Let students tickets = s
The auditorium at McCaskey East High School in Lancaster, PA has 800 seats. This will be:
a + s = 800 ..... i
Therefore, suppose that the drama club has a goal of making $3400. This will be:
7a + 4s = 3400 ..... ii
From equation i, a = 800 - s.
7a + 4s = 3400
7(800 - s) + 4s = 3400
5600 - 7s + 4s = 3400
Collect like terms
-7s + 4s = 3400 - 5600
3s = -2200
s = 2200 / 3
s = 733
a = 800 - 733 = 67
Therefore, there'll be 67 adults and 733 students.

(A) -1 (B) 3+4i/3 (C) 5+4i/5 (D) 3+4 i/ 5
The simplified form of (2 + i)/(2 - i) is (3 + 4i)/5
A Simple Form or simplified form can be defined as When a fraction's numerator and denominator share only one common factor, it is said to be in its simplest form.
Consider the given complex number(2 + i)/(2 - i)
Multiply both numerator and denominator with the complex number (2 + i), and we get
{(2 + i) × (2 + i)} / {(2 + i) × (2 - i)}= {(2 + i) × (2 + i)} / (2² - i²)
(using the formula (x + y)(x - y) = x² - y²)= {(2 + i) × (2 + i)} / (4 - (-1))= {(2 + i) × (2 + i)} / (4 + 1)= {(2 + i) × (2 + i)} / 5= (2² + 2i + 2i + i²)/5= (4 + 4i + (-1))/5= (3 + 4i)/5

According to the question the expression that we have been given to us is :

Note that we know the property of exponent which states that if teh exponents with same base and different power are divided then the powers are subtracted. That is,
[tex]\frac{x^{m} }{x^{n} } = x^{m-n}[/tex] (1)
Now using this rule we will evaluate the equation given that is

If you can fit 19 people in a 5ft x 5ft square, how many people would fit along a parade route, 10ft deep on each side of the street and one mile long?
There are 40128 peoples in the parade route by proportion.
According to the given question.
You can fit 19 people in a 5ft x 5ft square.
Here we need to find the number of peoples in the 10ft x 1 mile parade.
Since, we have to convert miles into feet then,
1 mile = 5280 feet
We know that the parade route is in the form of rectangle.
Also, the process of proportion reasoning involves understanding the multiplicative relationships between rational quantities.
Now we will find the number of peoples by proportions,
Let us consider the number of people in the rectangle as x.
Therefore,
19/25 = x/5280
⇒ (19/25)(5280) = x
⇒ x = 40128
Hence, there are 40128 peoples in the parade route by proportion.

The perimeter of a rectangle is 102 feet. Find the length and width if the length is an integer and the width is 3 times the next consecutive integer.
Length = [_] feet
Width = [_] feet
The length of the rectangle is 12feet and the width is 26feet.
Perimeter of a rectangleThe formula for calculating the perimeter of a rectangle is expressed according to the equation below:
Perimeter = 2(length + width)
If the width is 3 times the next consecutive integer, then;
w = 3(x+1)
l = x
Substitute
102 = 2(x + 3x + 3)
102 = 2(4x + 3)
102/2 = 4x+ 3
51 = 4x + 3
4x = 48
x = 12 = length
For the width
width = 2(x+1)
width = 2(12+1)
width - 26 feet
