Write the slope-intercept equation of a line that passes through the points (-2, 5) and (6, -4)
The slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is y = (-9/8)x + 11/4.
According to the question.
A line passes through the two points (-2, 5) and (6, -4).
As we know that, the slope intercept formula y = mx + b is used when you know the slope of the line to be examined and the point given is also the y intercept (0, b). In the formula, b represents the y value of the y intercept point.
So, the slope of the line = -4 -5/(6 + 2) = -9/8
And, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is given by
y = (-9/8)x + b
Since, the line passes through (-2, 5) and (6, -4). So, both the points must statisfy the above equation.
⇒ 5 = (-9/8)(-2) + b
⇒ 5 = 9/4 + b
⇒ b = 5 - 9/4
⇒ b = (20 - 9)/4
⇒ b = 11/4
Therefore, the slope intercept form of a line which passes through the points (-2, 5) and (6, -4) is y = (-9/8)x + 11/4.

The seaside train runs along a 156 mile route that takes 3 hours to complete. if it always runs at the same speed, write an equation to represent the distance and time.
The equation to represent the relationship between Distance and Time will be 52y = x, where Speed remains constant
In the given question, it is said that the train runs along a distance of 156 miles, which takes 3 hours to complete.
The equation that represents the relationship between Speed, Distance, and Time is as follows :
=> Speed = Distance/Time
It is also stated that the train runs at the same speed so the Speed will be constant while deriving the relationship between Distance and Time.
First, we have to find the speed of the train with the given Distance & Time by the formula => S = D/T, where Speed = S, Distance = 156 miles, and Time = 3 Hours
=> S = 156/3 => S = 52 miles/hour
As we got our constant speed for the train, We can now find out the Distance Time relation of the train. By taking Distance = x, Time = y, Speed = 52 miles/hour
=> 52 = x/y => 52y = x
Hence, we get the relationship between Distance and Time where Speed is constant at 52 miles/hour

each year a certain amount of money is deposited in an account which pays an annual interest rate of r at the end of each year the balance in the account is multiplied by a growth factor of x = 1 + r. 1,000 is deposited at the start of the first year, an additional 300 is deposited at the start of the next year and 500 at the start of the following year
1. write an expression for the value of the account at the end of three years in terms of the growth factor x
2. determine to the nearest cent the amount in the account at the end of three years if the interest rate is 4 %
Check the picture below.
now if the interest rate is 4%, that's in percentage form, we need to use the decimal version of it, namely 4/100 = 0.04, and since we know that x = 1 + r, whilst r = 0.04, that means that x = 1 + 0.04, x = 1.04.

Find the degree measure of each angle in the triangle
The degree measure for angle B is 28° and angle D is 62°.
We are given that:
∠ C = 90°
∠ B = ( 2 x + 10 )°
∠ D = ( 5 x + 17 )°
Now, using the angle sum property of a triangle, we get that:
∠B + ∠ C + ∠ D = 180°
Substituting the values:
2 x + 10 + 90 + 5 x + 17 = 180
7 x + 117 = 180
7 x = 63
x = 63 / 7
x = 9
∠ B = ( 2 x + 10 )
∠ B = 2(9) + 10
∠ B = 18 + 10
∠ B = 28°
∠ D = ( 5 x + 17 )
∠ D = 5 (9) + 17
∠ D = 45 + 17
∠ D = 62°
Therefore, the degree measure for angle B is 28° and angle D is 62°.

We are given some coordinates:
T(0, - 2), U(2, - 1), V(3, - 4)
We have to first plot them on a graph.
Now, we have to reflect them over x - axis.
To reflect over x- axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.
For point T:
Additive inverse of - 2 = 2
T' = (0, 2)
For point U:
Additive inverse of - 1 = 1
U' = (0, 1)
For point V:
Additive inverse of - 4 = 4

The perimeter of the triangle formed by the points B(7,-9), C(7,-2) and D(0,0) is 25.68 square units.
Perimeter is defined as the distance or the enclosed path that surrounds the 2-D shapes or polygon. The perimeter of a triangle is the sum of all the three sides of a triangle.
The perimeter of a triangle formed by the points B(7,-9), C(7,-2) and D(0,0) can be determined by finding the distance between two points.
The distance between two points A(x1,y1) and B(x2,y2).
√[(x2-x1)²+(y2-y1)²]
Therefore, BC = √(7-7)²+(-2+9)²
BC = √49
BC = 7 square units.
and CD = √(0-7)²+(0+2)²
CD = √53
CD = 7.28 square units.
and DB = √(7-0)²+(-9-0)²
DB = √130
DB = 11.40 square units.
Therefore, perimeter of triangle formed from given points is BC+CD+DB = 7+7.28+11.40 = 25.68 square units.

Given a table that showing different prices for cans of soup as shown in attached image.
Here, we will calculate the price of 1 quantity of each type of soup.
The Price of 3 quantities of soup price A=$3.87
Now, we will find the price of soup A for the 1 quantity.
The Price of 1 quantity of soup price A=$3.87/3=$1.29
The Price of 2 quantities of soup price B=$2.38
Now, we will find the price of soup B for the 1 quantity.
The Price of 1 quantity of soup price B=$2.38/2=$1.19
The Price of 7 quantities of soup price C=$8.75
Now, we will find the price of soup C for the 1 quantity.

What is a dot-product?The dot product, also known as the scalar product, is an algebraic operation that takes two sequences of numbers of equal length (often coordinate vectors) and outputs a single number. The dot product of two vectors' Cartesian coordinates is frequently used in Euclidean geometry. Although other inner products can be defined in Euclidean space, it is frequently referred to as the inner product (or, less frequently, projection product) of Euclidean space (see Inner product space for more).
The sum of the products of the matching entries of the two number sequences is the dot product, according to algebra. B, it is the result of adding the cosine of the angle between the two vectors and the Euclidean magnitudes of the two vectors.
The vectors that make up the triangle must first be located. The vertices are subtracted to achieve this.
QP=(2,0,-4)-(1,-3,-2)=(1,3,-2)
PR=(1,-3,-2)-(6,-2,-5)=(-5,-1,3)
RQ=(6,-2,-5)-(2,0,-4)=(4,-2,-1)
QP.PR = (1, 3, -2).(-5, -1, 3) = -5-3-6= -14
PR.RQ = (-5, -1, 3).(4, -2, -1) = -20+2-3 = -21
RQ.QP = (4, -2, -1).(1, 3, -2) = 4-6+2 = 0
Calculate the dot products to see if these vectors are perpendicular now.
They are perpendicular if the dot product of two vectors equals zero. As you can see, RQ.QP is zero in your triangle, which supports this. Consequently, a right-angled triangle results.

The median of a set of numbers is the middle number in the set (after the numbers have been arranged from least to greatest) -- or, if there are an even number of data, the median is the average of the middle two numbers.
For example:
Find the median of the set {2,5,8,11,16,21,30} .
There are 7 numbers in the set, and they are arranged in ascending order. The middle number (the 4 th one in the list) is 11. So, the median is 11.
The center of a data set is also a way of describing the location. The two most widely used measures of the center of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50. To find the median weight of the 50 people, order the data, and find the number that splits the data into two equal parts. The median is generally a better measure of the center when there are extreme values or outliers because it is not affected by the precise numerical values of the outliers.
