∠1 and ∠8 are alternate exterior angle.
∠2 and ∠4 are corresponding angle.
∠3 and ∠6 are alternate interior angle.
∠6 and ∠7 are consecutive interior angle.
What is alternate exterior angle ?When a transversal intersects two or more lines, alternate exterior angles are produced. These angles are created on the various transversal sides' outer sides.Any two parallel lines that cross a transversal produce a few pairs of angles with the transversal. In the area inside the parallel lines, interior angles are generated, whilst alternate external angles are created in the area outside the parallel lines.
what is corresponding angle ?Corresponding angles are those that are created when two parallel lines are intersected by another line, whether it be a transversal or a matching corner (i.e. the transversal). Angle p and angle w, for instance, are the matching angles in the illustration below.
What is alternate interior angle ?The pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. All of these angles are equal. There is another way to look at this. The alternative interior angles can establish the parallelism or non-parallelism of the given lines. The supplied lines that are crossed by a transversal are said to be parallel if these angles are equal.
What is consecutive interior angle ?The pair of interior angles that are not contiguous to one another and are on the same side of the transversal are referred to as consecutive interior angles. Things that follow one another are referred described as being "consecutive." On a transversal's internal side, adjacent interior angles are found next to one another.

Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form.
(-3,5), (9,1)
What is the point-slope form of the equation of the line?
(Simplify your answer. Use integers or fractions for any numbers in the equation.)
The x and y coordinates of the line are utilized to compute the steepness of the line using the slope formula.We are aware that one of a line's most crucial qualities is its slope because it aids in determining the pace of change.
What is the point-slope form of the equation of the line?
A line's steepness can be determined by looking at its slope.Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Using the formula
m=y2y1/2x1,
which is the change of y over the change of x, determine the slope of the line between (3,5) and (9,1).
Slope is equal to the change in y over the change in x
, or rise over run.
m=change in y /change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
To determine the slope, enter the values of x and y into the equation.
m=1−(5)/9−(−3)
m=-4/12
m=12/4
m=3
To replace x1 and y1 in the point-slope form yy1=m(xx1), which is derived from the slope equation
m=y2y1/x2x1,
use the slope 3 and the specified point (3,5).
y−(5)=3(x+3)
Keep the equation in point-slope form and make it simpler.
y−5=3(x+3)

As per the long division, the value of 19 divided by 6,927 is 0.002742
Long division:
Long division is the mathematical method for dividing large numbers into multiple smaller groups or parts. The number which we divide into small groups is called the dividend, the number by which we divide is called the divisor.
Given,
Here we have to divide the number 19 by 6927.
When we divide the number, we have to following the following steps,
1) Set up the problem with long division bracket. Put dividend inside bracket and divisor on outside left.
2) 6927 goes into 19000 (2-times). Put a 2 in the next place of quotient and multiply 6927 by 2 to get 13854. Subtract 13854 from 19000 to get remainder (19000-13854=5146).
3) Now, bring down 0 from the dividend, to make 51460
4) 6927 goes into 51460 (7-times). Put a 7 in the next place of quotient and multiply 6927 by 7 to get 48489. Subtract 48489 from 51460 to get remainder (51460-48489=2971).
5) Now, bring down 0 from the dividend, to make 29710
6) 6927 goes into 29710 (4-times). Put a 4 in the next place of quotient and multiply 6927 by 4 to get 27708. Subtract 27708 from 29710 to get remainder (29710-27708=2002).
7) Now, bring down 0 from the dividend, to make 20020
8) 6927 goes into 20020 (2-times). Put a 2 in the next place of quotient and multiply 6927 by 2 to get 13854. Subtract 13854 from 20020 to get remainder (20020-13854=6166).
This process is continued so we have to take only up to these one.

Peter has 480 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed area. What is the maximum area?
A rectangle that maximizes the enclosed area has a length of _____ yards and a width of _____
1. Length of rectangular area = 120 yards
Width of rectangular area = 120 yards
2. Maximum area = 14,400 square yards.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Total fencing Peter has = 480 yards
Now,
We can say that the total fencing he has in terms of length L and width W of the rectangle will be;
⇒ L + L + W + W = 480
⇒ 2(L+W) =480
Divide both sides by 2 to get
⇒ L+W = 240
Subtract W from both sides so we get L in terms of W;
⇒ L= 240 - W
Since, The area of a rectangle is Length times width.
So, Area = (L × W)
⇒ Area = (240-W) W
⇒ Area = 240W - W²
Now, By comparing the equation with an quadratic equation
ax² + bx + c , we get;
⇒ a = -1 and b = 240
Since, Area is maximum when;
W = -b/2a
W = - 240/-2
W = 120
So, for W = 120 yards area is maximum.
Hence, Length of yards = 240 - 120 = 120 yards.
(b) Maximum area of the rectangle can be found by substitute this
W = 120 in the Area equation;
So, the maximum area ,
A = 240 (120) - 120²
A = 28800 - 14400
A = 14400
Hence, Maximum area = 14,400 square yards.
Thus,
1. Length of rectangular area = 120 yards
Width of rectangular area = 120 yards

The volume of a cylinder is the product of its base area and its height. In this problem, the radius of the base of the cylinder is 5 mm, and its height is 25.5 mm. The volume is,
[tex]V=B\cdot h=(\pi\cdot r^2)\cdot h=\pi\cdot5^2mm^2\cdot25.5mm=\pi\cdot25\cdot25.5mm^3=637.5\pi\text{ }mm^3[/tex]Hence, the volume is 637.5π mm³.
Find 3/4 divided by 2/3 then draw a picture and write an explanation describing how to get the answer.
The outcome of the quotient between the two fractions 3/4 and 2/3 is 9/8
How to find the quotient between the two fractions?So let's define two fractions as:
a/b and c/d.
The quotient between the fractions a/b and c/d can be written as:
(a/b)÷(c/d).
Now, the quotient is equal to the product with the inverse, so we can rewrite this as:
(a/b)÷(c/d) = (a/b)*(d/c)
Now, in this case, we want to find 3/4 divided by 2/3, this will be:
(3/4)÷(2/3) = (3/4)*(3/2) = 9/8

What is f^-1(-7) plus f(-7)? I need help answering this question
Answer:
13
Step-by-step explanation:
You want the sum of f^-1(-7) and f(-7) given the function definition in the table.
Inverse functionThe inverse function f^-1(x) consists of ordered pairs that are the reverse of the ordered pairs (x, f(x)). That is ...
(x, f^-1(x)) ≡ (f(x), x)
Another way to describe f^-1(x) is "the value of z that gives f(z) = x". This means f^-1(-7) is the value of x that gives f(x) = -7. That x-value is 6:
f^-1(-7) = 6 . . . . . from the 4th column of the table
Function valueWe can read the function value directly from the table:
f(-7) = 7 . . . . . . the first column of the table
SumThen the sum of interest is ...
f^(-1)(-7) +f(-7) = (6) +(7)
f^(-1)(-7) +f(-7) = 13

Additional comment
The inverse function ordered pairs are ...
(x, f^-1(x)) = {(7, -7), (12, 11), (8, -13), (-7, 6), (13, 5)}
