What is an example of parallel lines?
Two lines that are equally spaced apart from one another and never cross each other are said to be parallel lines.
Both horizontal and vertical shapes are possible. In our daily lives, parallel lines can be seen in the form of zebra crossings, rows of notebooks, and the nearby railroad tracks.
from the figure , we understand that ∠1 and ∠3 together from a straight line.
thus, ∠1 + ∠3 = 180°
25° + ∠3 = 180°

What does math's slope intercept form mean?
A line's equation can be written in the slope-intercept form such that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are instantly visible.
This form is frequently known as the y = mx + b form.
y = mx + b
Parallel lines have the same slope, so
m = -5
y = -5x + b

Compare the function f(x)=3x-1/2 to the function shown in the graph. Which statements are correct?
Answer: B
Step-by-step explanation:
For [tex]f(x)=3x-\frac{1}{2}[/tex], comparing it with slope-intercept form yields that the slope is [tex]3[/tex] and the [tex]y[/tex]-intercept is [tex]-1/2[/tex].
For the graphed function, the slope is [tex]\frac{-4-0}{-2-6}=\frac{1}{2}[/tex] and the [tex]y[/tex]-intercept is about [tex]-3[/tex].
Since the absolute value of the slope of the graphed function is less than that of [tex]f(x)[/tex], option B is correct.

Given, the [tex]n^{th}[/tex] term of a sequence is: [tex]u_{n}[/tex] = 5 - 4n
We need to find the first three terms, then n= 1, 2, 3 respectively
So, first term, n = 1, [tex]u_{1}[/tex] = 5 - 4*1 = 5 - 4 = 1
second term, n = 2, [tex]u_{2}[/tex] = 5 - 4*2 = 5 - 8 = -3
third term, n = 3, [tex]u_{3}[/tex] = 5 - 4*3 = 5 - 12 = -7
Hence, the first three terms of the sequence are 1, -3, and -7 respectively.

The equation of line which is perpendicular to the given line and passes through the points ( 3, 4) is y = 3x + 5
What is slope intercept form ?The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible.
The slope intercept form of a straight line equation can be written as :
y = mx + c
Where
m = slope = (change in the y-value) axis's / (change in the value of x in the x axis)
The given line's equation is
y = - x/3 + 5
Slope = - 1/3 as compared to the slope intercept form.
The slope of one line is equal to the negative reciprocal of the slope of the other line if two lines are perpendicular.
As a result, the slope of the line through (3, 4) is 3.
In order to calculate the intercept, we would replace m with 3, x with 3 and y with 4
The equation becomes
4 = 3 × 3 + c
c = -5
putting the value of c and m in the slope intercept form equation
We get
y = 3x - 5
The equation of line which is perpendicular to the given line and passes through the points ( 3, 4) is y = 3x + 5

Answer:
A.) y = –3x + 4 and y = –3x – 4
Step-by-step explanation:
The first equation of a system of equations is y = -3x + 4 and the second equation is y = -3x - 4.
We can see that both equations have the same slope of -3 and have different y-intercepts of 4 and -4, respectively.
Because the two lines are parallel, they will never intersect and will overlap each other, resulting in an infinite number of solutions.
Therefore, the system of equations y = –3x + 4 and y = –3x – 4 has infinitely many solutions.

Piper works in a department store selling clothing. She makes a guaranteed salary of $250 per week, but is paid a commision on top of her base salary equal to 15% of her total sales for the week. How much would piper make in a week in which she made $2050 in sales? how much would piper make in a week if she made xx dollars in sales?.
If a piper will make $2050 in sales in a week than she will get 557.5$ including her commission and salary.
What is commission in money?A sales commission is a payment made to an employee after they successfully complete a task, typically selling a predetermined volume of goods or services. Sales commissions are a common incentive used by employers to boost employee productivity. A commission can be paid instead of or in addition to a salary.
As she makes a guaranteed salary of $250 per week
and paid a commission equal to 15% of her total sales for the week
if she made $2050 in sales in a week
so calculating it 15% commission
=(15x2050)/100
=307.5$
now adding the salary with commission:
=$250+307.5$
=557.5$

Answer: 26
Step-by-step explanation:
let t = thomas's age
104 = (3t) + t
104 = 4t
t = 26
Answer: 26 years old
Step-by-step explanation:
We will write a system of equations to help us solve, let h be equal to Huilan's age and t be equal to Thomas's age.
h = 3t
h + t = 104
Now, we will solve by substituting the first equation into the second.
Then, we will simplify the equation on the left side by combining like terms and dividing both sides of the equation by 4 to isolate the variable.
h + t = 104
(3t) + t = 104
4t = 104
t = 26

Left hand side is equal to right hand side that is 7x+19 the missing term is 2x+31 we get equation as 7x+19= 4x+x-12+2x+31.
Given that,
We have to find the fill the blank of the equation with infinite solution is 7x+19= 4x+x-12+------
We know that,
Take the equation
7x+19= 4x+x-12+------
We have to find the missing terms so that the right hand side is equal to left hand side.
Right hand side is 7x+19
Left hand side is 4x+x-12+------
5x-12+----
To get 7x we have to add 2x and to get +19 we have to add 31 to left hand side.

Manas is half his sister's age.
She is eight years younger than
Uncle Mike. Mike is the sum of a
dozen and a score.
In how many years time will the sum of Manas' age and his
sister's age be 48 years?
Answer: In 6 years the sum of Manas' age and his sister's age will be 48 years.
Step-by-step explanation:
We know that value of a dozen is 12 and the score is 20.
Hence,
Uncle Mike's age = 12+20 = 32 years
Since Manas' sister is 8 years younger than Mike,
Her age = 32 - 8 = 24 years
We know that Manas is half her age. Therefore,
Manas' age = 24 ÷ 2 = 12 years
After x years the sum of Manas' age and his sister's age will be 48 years.
Manas' future age = (12 + x) years
His sister's future age = (24 + x) years
The Sum of their ages is 48 years. Hence,
(24 + x) + (12 + x) = 48
36 + 2x = 48
2x = 48 - 36
2x = 12
x = 12 ÷ 2
x = 6
Therefore, in 6 Years sum of their ages is 48 years.

The value for df within in an experiment with two levels of factor a and three levels of factor b and five samples for each treatment condition is between 3.
Explain the term levels of factor?In a two-way ANOVA, the 2 separate variables are known as factors. Two variables, or factors, are supposed to influence the dependent variable. There will be two or even more levels inside each factor, and there are one less degrees of freedom per factor than there are levels.Let n1 represent factor A's level of freedom.
Let n2 represent factor B's degree of freedom.
If factor A has five levels, then n1 = 2.
If Factor B has seven levels, then n2 = 3.
The formula is used to express how the degrees of freedom interact;
df = (n1 - 1)+(n2 - 1) (n2 - 1)
df = n1 -1 + n2- 1
df = n1 + n2 -2
Replace n1 and n2 to obtain df;
df = 2 + 3 - 2
df = 3

A linear regression equation that represents this set of data is y = 31x + 799.8.
The calendar year in which the number of new cases would reach 1141 is 2022.
How to write the linear regression equation?In this scenario, the Year since 2011 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.
On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.
By critically observing the scatterplot (see attachment) which models the relationship given in the table for the Year since 2011 (x) and the New cases (y), an equation for the linear regression is given by:
y = 31x + 799.8
Now, we can estimate the calendar year in which the number of new cases would reach 1141:
1141 = 31x + 799.8
31x = 1141 - 799.8
31x = 341.2
x = 341.2/31
x = 11.0
