Answer:
The value of x can be 10
The value of y can be -4
Step-by-step explanation:
Assume the function is linear of the form
y = mx
When x = 5, y = -2
Simply multiply x by 2 and equivalently multiply -2 by 2
x = 5 x 2= 10
y = -2 x 2 = -4
write an equation in slope intercept form of the line that passes through (2,8) and (-3,6)
The equation of the line that passes through the point (-6,8) and has a slope of -5/3 is y=-5/3x-2.
Given that the line passes through the point (-6,8) and has a slope of -5/3.
We are required to find the equation of the line whose description is given.
Equation is basically the relationship between two or more variables that are expressed in equal to form. It may be linear equation, quadratic equation or cubic equation. Slope intercept form in the equation be y=mx+c.
We have been given slope be -5/3.
y=mx+c--------------1
Put m=-5/3 in equation 1.
y=-5/3x+c------------2
Put (-6,8) in equation 2.
8=-5/3 *(-6)+c
8=-5*(-2)+c
8=10+c
c=-2
Use the value of c in equation 2.
y=-5/3x-2
Hence the equation of the line that passes through the point (-6,8) and has a slope of -5/3 is y=-5/3x-2.

Answer:The width of the rectangle is 1 unit
Step-by-step explanation:Let the length of the rectangle be x
let the breadth be x-5
Since ,area of rectangle=length*breadth
area = x*(x-5)
6=x^2-5x
x^2-5x-6=0
solving the above equation,
x^2-(6x-x)-6=0
x^2-6x+x-6=0
x(x-6)+1(x-6)=0
(x-6)(x+1)=0

The scale factor of the preimage to the image is 5/2
The length of BC is 10 units
How to find the scale factor of the preimage to the image?The scale factor is the size by which the shape is enlarged or reduced. It is used to increase the size of shapes like circles, triangles, squares, rectangles, etc.
The scale factor of the preimage to the image can be found by finding the ratio of the corresponding sides of the preimage to the image. That is:
scale factor = DC / D'C'
scale factor = 5/2
Also, the scale factor = BC / B'C' and the scale factor is constant (i.e. 5/2)
scale factor = BC / B'C'
5/2 = BC/4
BC = 5/2 * 4
BC = 10 units

what is coefficient of variation calculator
The coefficient of variation (CV) calculator is a tool that helps you calculate the relative variability of a dataset. The coefficient of variation is the ratio of the standard deviation (SD) to the mean (μ) expressed as a percentage, and it is used to compare the variability of datasets with different units or scales.
The formula for the coefficient of variation is:
CV = (SD / μ) x 100%
To use a coefficient of variation calculator, you need to input the values of the dataset, either one by one or as a list, and select the type of data you have (sample or population). The calculator will then calculate the mean, standard deviation, and coefficient of variation of the dataset.
The coefficient of variation is commonly used in quality control, finance, and other fields to compare the variability of different datasets. A high coefficient of variation indicates that the dataset has a large amount of variability relative to the mean, while a low coefficient of variation indicates that the dataset has a small amount of variability relative to the mean.
The coefficient of variation is only meaningful when the mean is non-zero. If the mean is zero or close to zero, the coefficient of variation can be infinite or undefined.

What is the total amount spent and the final temperature?In order to determine if your friend has enough money to buy all the items, the total cost of the items have to be determined. The total cost is the sum of all the items bought.
here, we have,
Total cost = total cost of the first three items + total cost of the second three + total cost of the last three
Total cost = (3 x 15.99) + (3 x 10.40) + (4 x 4.50)
Total cost = $47.97 + $31.20 +18
Total cost = $97.17
An increase in temperature would be represented with a positive number. While, a decrease in temperature would be represented with a negative number. The final temperature can be determined by adding the temperature increase and decease together.
Final temperature = increase in temperature - decrease in temperature
Final temperature = 32 - 14 = 18 degrees

How do you find the coordinates of a polar point?
To discover the coordinates of a polar point, you need to recognize its distance from the origin (the polar axis) and the perspective it makes with the superb x-axis.
The space is commonly denoted via the image r, and the angle is denoted by means of the image θ. To devise a polar point, you start by locating the foundation and drawing a line alongside the polar axis.
Subsequently, you measure the angle θ from the fine x-axis, shifting counterclockwise.
In the end, your degree the distance r from the starting place and plot the factor on the corresponding location.
To find the coordinates of a polar point, you can use the subsequent formulas:
x = r cos(θ)
y = r sin(θ)
Right here, x and y constitute the rectangular coordinates of the factor, while r and θ constitute the polar coordinates.
Those formulas let you convert between polar and rectangular coordinates, which can be useful for graphing and solving problems in diverse branches of mathematics and physics.

What are the trigonometric ratios?The three trigonometric ratios are defined as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the adjacent side.For the height, we have that:
The opposite angle is of 32º.The side adjacent to the angle of 32º is of 71 feet.Hence the height is obtained as follows:
tan(32º) = h/71.
h = 71 x tangent of 32 degrees
h = 44.4 feet.

What is a matrix?A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics. In computer graphics, where they have been used to describe picture rotations and other transformations, matrices have vital applications as well.
Mathematically, assume that B = {v₁, v₂, v₃, ........} is the set of vectors. Then B will be linearly independent if the vector equation
y₁v₁ + y₂v₂ + y₃v₃ + ........ = 0 possesses the trivial solution such that
y₁ = y₂ = y₃ = ........ = 0.
Let A be a matrix, then columns of A will be linearly independent if the equation Ax = 0 possesses the trivial solution. In other words, The row space of matrix A is the span of its rows. The column space denoted by
C(A) is the span of A’s columns. The dimension of the row and column spaces is always the same, which is known as the rank of A.
