Step-by-step explanation:
The sides on the smaller triangle are 15, 25, and 30.
The sides of the larger triangle are 42, 70, and 84.
15*X = 42
X = 2.8
25 * 2.8 = 70
30 * 2.8 = 84
Since all sides of the larger triangle are 2.8 times the sides of the smaller triangle, the two triangles are similar.

Just add or subtract an m value for all X coordinates as well as add or subtract an n value for all Y coordinates of the figure.
P(X; Y) → P'(X ± m; Y ± n)If the figure has 3 points (A, B and C), we would be left with:
A(X, Y) ; B(X₂; Y₂) ; C(X₃; Y₃)
A(X, Y) → A'(X ± m; Y ± n)
B(X₂; Y₂) → B'(X₂ ± m; Y₂ ± n)
C(X₃; Y₃) → C'(X₃ ± m; Y₃ ± n)
in our example - see attached figure - let
m = 4
n = - 1
(these values of m=4 and n=-1 were chosen by me arbitrarily)
A(1; 2) → A'(1 + 4; 2 - 1) ⇒ A'(5; 1)
B(2; 3) → B'(2 + 4; 3 - 1) ⇒ B'(6; 2)
--------------------------------------------------------------------------
Rotations
The expression (formula) for rotation will be:
P(X; Y) → P'(Xcos θ - Ysen θ; Xsen θ + Ycos θ)
Let rotate 90° (counter-clockwise): cos 90 = 0 and sen 90 = 1, then
P(X; Y) → P'(-Y; X)in our example - see attached figure
A(1; 2) → A''(-2; 1)
B(2; 3) → B''(-3; 2)

can someone solve m - 4m= -6 step by step please?
Answers
Answer:
m = 2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
m - 4m = -6
Step 2: Solve for m
Combine like terms: -3m = -6Divide -3 on both sides: m = 2Step 3: Check
Plug in m into the original equation to verify it's a solution.
Substitute in m: 2 - 4(2) = -6Multiply: 2 - 8 = -6Subtract: -6 = -6Here we see that -6 does indeed equal -6.
∴ m = 2 is the solution to the equation.
Abe starts working out at a gym and begins to lose weight. His weight can be calculated using the equation y = 250 − 3x where y is his current weight and x is the number of weeks he has been working out. Which statement best describes Abe's weight loss?
Answers
Answer:
The number of weeks Abe has been working out is the independent variable in the equation.
Step-by-step explanation:
Since Abe's weight is given by the equation
y = 250 − 3x
Every increase or decrease in the value of x in the equation will invariably lead to a change in the value of y.
If for instance Abe works out 5 weeks, her weight would be:
y= 250- 3*5
y=250-15
y=235
If she works out 3 weeks, her weight would be
y=250-3*3
y=250-9
y=241
Hence y weight is dependent variable while x weeks worked out is the independent variable in the equation

Answers
The constant of proportionality is comes out to be 3.
What is constant of proportionality?When two variables are proportional to one another, their relationship can be expressed as y = kx or y = k/x, where k defines how the 2 factors are related to one another. The above k is recognized as the proportionality constant.
The proportionality constant is the constant value of the ratio of two proportional quantities. When the ratio or product of two varying quantities yields a constant, they are said to be in a proportional relationship. The proportionality constant's value is determined by the type of proportion between both the two given quantities: direct variation or inverse variation.Now according to the question.
The proportionality constant denotes the ratio of the words x and y.
It is found by dividing Δy by Δx.
Δy/Δx = (y₂ - y₁)/(x₂ - x₁)
Consider two values from the table;
y₂ = 39 ; x₂ = 13
y₁ = 30 ; x₁ = 10
Substituting the values in the formula;
Δy/Δx = (39 - 30)/(13 - 10)
Δy/Δx = 9/3
Δy/Δx = 3
Therefore, the value of constant of proportionality is 3.

Christie has a total of 15 pieces of fruit are bananas and apples worth $1.59 bananas are $.13 each and apples are seven cents each how many bananas and how many apples does she have
Answers
Answer:
a = apple
b = banana
a + b = 15 so a = 15 - b
0.07a + 0.13b = 1.59
substitute a = 15 - b into 0.07a + 0.13b = 1.59
0.07a + 0.13b = 1.59
0.07(15 - b) + 0.13b = 1.59
1.05 - 0.07b + 0.13b = 1.59
0.06b = 0.54
b = 0.54/0.06
b = 9
a = 15 - b
a = 15 - 9
a = 6

Based on what we established about the classification of x and using the closure of integers, what does the equation tell you about the type of number x must be for the sum to be rational? What conclusion can you now make about the result of adding a rational and an irrational number?
Answers
The conclusion that we now make about the result of adding a rational and an irrational number is that the sum of any rational number and any irrational number will always be an irrational number.
What is a rational number?Irrational numbers cannot be stated as a fraction, although rational numbers can be expressed as ratios (such as P/Q and Q). However, both of the numbers are genuine and can be shown on a number line.
It should be noted that the conclusion that we now make about the result of adding a rational and an irrational number is that the sum of any rational number and any irrational number will always be an irrational number.
For example, we can conclude that ½+√2 is irrational.

What is the least amount of information that you need to construct a triangle congruent
Answers
Answer:
6 points of data, minimally.
Easiest if they are 3 points.
All data is going to be comprised of more than one unit of data itself.
For 3 points, we need 6 coordinates.
For 3 lines, we need 2 points each, and then 2 coordinates for each point.
Pretty much since any other way to describe it is relying on points, I would say 3 points, each comprised of 2 coordinates are necessary as a minimum.
Even an angle is defined from points. The angular distance between two lines relies on the two lines, which each relies on 2 points to describe, and each point is 2 coordinates.
So in a 2D space, the information required to make a figure is twice the number of vertices.
Assuming a pattern, in 3D space, a cube would be minimally determined as 8 vertices times the 3 coordinate requirements of each. 24 data points to minimally describe a cube.
“A figure can precisely and minimally be described by a number of data points equal to its vertices multiplied by the number of dimensions it exists in.”
Edit… A closed figure made only of straight line segments.

The total amount of money Sarah will spend is given by the equation y=1.5x+16 where y represents the total amount of money, in dollars and cents, and x represents the number of rides Sarah goes on. What is the meaning of the y-value when x=1?
Answers
Sarah had spent a total amount of $17.5 as y represents the total amount when x which represents the number of rides which will be 1.
In the given question, It is stated that Sarah had a set price for admission and for ride tickets. The equation representing this situation given in the question is y = 1.5x + 16, where y represents the total amount of money Sarah will spend, and x represents the number of rides she will have in the park.
We have been given a situation in which the value of x is set to be 1. So, taking x = 1 in the equation y = 1.5x + 16, We get :
=> y = 1.5(1) + 16 => y = 17.5
Here we get y = 17.5 which will be the total amount Sarah will spend in the amusement park.
Hence, when x = 1, y tells us the total amount Sarah spends in the amusement park which will be $17.5
