The expression that can be used to determine the slope of the line is (1 + 4)/(-3 - 2)
What are slopes?The slope of a line is the gradient or the average rate of change of the line or a line equation
Note that linear equations are equations that have constant average rates of change, slope or gradient
How to determine the slopes?The two points are given as
(2,-4);(-3,1)
The slope of a line is calculated using
m = (y2 - y1)/(x2 - x1)
Substitute the coordinates of the points in the above equation
m = (1 + 4)/(-3 - 2)
Evaluate the numerator
m = 5/(-3 - 2)
Evaluate the denominator
m = 5/-5
Rewrite the quotient as
m = -5/5
Evaluate the quotient
m = -1
Hence, the expression that can be used to determine the slope of the line is (1 + 4)/(-3 - 2)

The figure below is composed of square ABCD and equilateral triangle
Answer: 225°
Step-by-step explanation:
The correct option is D)
Refer Figure
Given:
ABCD is a square
ABP is an equilateral triangle
AB=BP=BC (△ABP is equilateral and AB and BC belong to a square, hence all are equal)
∠ABC=∠ABP+∠PBC=60°+∠PBC
90°−60°=∠PBC
∠PBC=30°
In △BPC
BP=BC
∠BPC=∠BCP= 2
180−∠PBC
( angles opposite to equal sides of a triangle are equal)
∠APC=∠APB+∠BPC=(60+75)°=135°
Hence, Reflex ∠APC=(360−135)°=225°

The sum of the two digits number is nine
If the sum of two digits t and u is t + u = 9, then the second equation is option 2: t = 1/2 u.
What is a digit?
In math, single integers called digits are used to represent values. To represent all mathematical values, the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 are employed in various combinations and repetitions.
The first equation is as given t + u = 9
Second equation t = u/2 since the number in the tens position is one half of the one in the units. So if you divide u by two, you should have one t, as the equation states.
The second equation is t = (1/2)u => u = 2t
When we replace this in first equation we get -
t + 2t = 9
3t = 9
t = 9/3
t = 3
When we replace it again in the equation -
u = 2 t
= 2 · 3
= 6
The requested number is 36.
Therefore, the number is 36 and the second equation is t=u/2.

The midpoint of AB = ([?], [])
When A point is (3, 1) and B point is (-1 , -1), the midpoint of AB is ( 2, 1) . The line segment's exact midway is where the midpoint is located.
what is mid point ?The term "midpoint" describes a point along a line that connects two points. The midway is situated between the two reference locations, which are the line's ends. The line connecting these two places is split into two equally sized sections by the middle. A point that splits a line segment into two equal halves is known as the midway. In other words, the line segment's exact midway is where the midpoint is located. It is demonstrably true that the middle of a number line has the same value as the average of any two matching places on the line.
given
midpoint of AB is equal to (x2 - x1) / 2 (3 + 1) / 2 = 2.
the midpoint of AB is 1

3(4x-10)= 2(3x-30) help
The solution to the equation 3(4x-10) = 2(3x-30) is x = -5.
What is algebra?
Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.
Let's solve for x:
3(4x - 10) = 2(3x - 30)
First, we can simplify both sides by distributing the coefficients:
12x - 30 = 6x - 60
Next, we'll move all the x terms to one side of the equation and the constants to the other side:
12x - 6x = -60 + 30
Simplifying further:
6x = -30
Finally, we can solve for x by dividing both sides by 6:
x = -5
Therefore, the solution to the equation 3(4x-10) = 2(3x-30) is x = -5.

suppose we want to choose 7 objects without replacement from 11 distinct objects  how many ways can this be done if the order of the choices is relevant
In 1663200 ways objects can be chosen if the order of the choices is relevant. The solution has been obtained using permutation.
What is permutation?
An arrangement of items in a specific manner or sequence is referred to as a permutation. It is important to think about both the selection and the arrangement when dealing with permutation. Briefly put, permutations depend much on ordering. In other words, a permutation is a combination that is ordered.
We want to choose 7 objects without replacement from 11 distinct objects
So, since the order of the choices is relevant, we will use permutation.
Therefore,
⇒nPr = n! ÷ (n - r)!
⇒11P7 = 11! ÷ (11 - 7)!
⇒11P7 = 11! / 4!
⇒11P7 = (11 * 10* 9 * 8 * 7* 6 * 5)
⇒11P7 = 1663200 ways
Hence, in 1663200 ways objects can be chosen if the order of the choices is relevant.

the volum of the wood in a tree varries directly as height and the square of length
Answer:
The volume of wood in a tree varies directly with the height and the square of the length of the tree. This means that if we increase the height of the tree, the volume of wood in the tree will also increase, and if we increase the length of the tree, the volume of wood will increase by the square of that increase.
This relationship can be expressed mathematically as:
V = khl^2
Where V is the volume of wood in the tree, h is the height of the tree, l is the length of the tree, and k is a constant of proportionality.
This relationship is based on the assumption that the cross-sectional area of the tree remains constant, and that the volume of wood in the tree is directly proportional to the height and the square of the length of the tree.

Therefore , the solution to the given problem of function comes out to be ss a result, Rolle's Theorem remains true.
What does the word function mean?Mathematics deals with numbers and their variants, formulae and associated structures, geometries and their areas, and locations where they might be found. The term "function" describes the connection between a group of input, of which each has a corresponding output. A function is an association among inputs and outputs where each input results in a single, unique output. A realm as well as a codomain, or scope, are assigned to each function. Functions are typically denoted by the letter f. (x). The input is an x. On activities, one-to-one activities, many-to-one functions, within operations, and on functions are the four main categories of functions that are available.
Here,
Consider
f(-1)=1-[tex](-1 )^{\frac {2}{3}}[/tex]=0
and f(1)=1-[tex](-1 )^{\frac {2}{3}}[/tex]=0
So, f(-1)= f(1) (1)
As a result of differentiating f(x) with regard to x, we now have
f'(x)= -2 / 3
Consequently, f'(0) is false.
So, at 0inleft (-1,1 ), f cannot be deduced.
Therefore, the given function in the range (-1,1) does not satisfy Rolle's theorem.
As a result, no c exists in (-1,1) for which f'(c )=0 even though f(-1)=f(1 ).
As a result, Rolle's Theorem remains true.

What are vertically opposite angles?
Opposite angles are the angles directly opposite each other where two lines cross. The intersection point is called the vertex, which is where the lines connect to form the angle. Opposite angles are also called vertical angles. In this instance, the word vertical refers to the vertex as opposed to direction.
We have given,
Two opposite angles:
(6x + 1)°, and 67°
So, We need to determine the value of x.
We know that the property of opposites angles, which the opposite angles are equal to each other.
So, (6x + 1)° = 67°
By calculating further:
6x + 1 = 67
6x = 67 - 1
6x = 66
x = 66/6

A vertical line in geometry is one that crosses the page from top to bottom.
What is meant by horizontal and vertical segments?A vertical line in geometry is one that crosses the page from top to bottom. Its cousin is the horizontal line that spans the page from left to right. A horizontal line and a vertical line are perpendicular.
Businesses utilize segmentation as a marketing strategy to focus on a certain market segment or type of customer. While vertical segmentation sharpens your marketing emphasis to target customers in a smaller demographic, horizontal segmentation entails offering a product to a broad range of consumers.
A horizontal object is one that is perpendicular to the horizon. Due to the fact that vertical is the polar opposite of horizontal, anything that forms a 90° (right angle) with either the horizontal or the horizon is referred to as vertical. This means that the horizontal line is one that crosses from left to right. Mathematical applications of the horizontal and vertical.
