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?
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

Answer:5 Hours
Step-by-step explanation:
160/4 = 40 miles per hour
200/40 = 5
Answer:
8 hours
Step-by-step explanation:
there are 360 miles total because it already covered 160 and there are 200 left. 160 / 4 = 4 hours per 40 miles. 200 is 40 more miles than 160. This means that it is the 4 hours of 160 miles in that 200 + 4 more hours for 40 miles. Add them together and you get 8 hours.

solve for x- 5(x+4)=30
Answer: x= -12.5
Step-by-step explanation:
Start with distributing-5(x+4) or you get
x-5x-20=30
Add x and -5x to get -4x
Thank you add 20 to each side and get
-4x = 50
Divide by -4 on each side to get x=-12.5
Answer:
x=-25/2 is the answer.
Step-by-step explanation:
Below are the steps for solving the equation:
Step 1: Simplify, combine like terms, and distribute:
x−5(x+4)=30
x+(−5)(x)+(−5)(4)=30
x+−5x+−20=30
(x+−5x)+(−20)=30
−4x+−20=30
−4x−20=30
Add 20 to each side:
−4x−20+20=30+20
−4x=50
Divide each side by -4:
-4x/-4=50/-4
x=-25/2, which is -12.5 as a decimal.
So, your answer is x=-25/2 as a fraction, which is also -12.5 as a decimal.

What is the least amount of information that you need to construct a triangle congruent
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.

Write a segment addition problem using three points that asks the student to solve for x but has a solution x=20
A segment addition problem with three points is: DE + EF = DF, which is 2x + 3x = 100. The solution is, x = 20.
How to Apply the Segment Addition Postulate?Assuming point E is located between points D and F on a straight line, points D, E, and F are collinear, and based on the segment addition postulate, we have the equation that is true:
DE + EF = DF.
Let's assume that we have the following lengths:
DE = 2x
EF = 3x
DF = 100
Therefore, we would have the following:
2x + 3x = 100
5x = 100
5x/5 = 100/5
x = 20.
Therefore, a segment addition problem with three points is: DE + EF = DF, which is 2x + 3x = 100. The solution is, x = 20.

washington high school's head tennis coach, ms. racket, runs a tennis camp for middle school students every summer. the students bring their own lunches, but ms. racket provides them with snacks.there is a proportional relationship between the number of students who enroll in ms. racket's tennis camp, x, and the total number of snacks she buys, y.what is the constant of proportionality? write your answer as a whole number or decimal.snacks per student
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.

terms.
(8,7) & (4,5)
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
To find the slope you can use the slope equation:
[tex]slope = \frac{y2 - y1}{x2 - x1}[/tex]
Let's define the terms in the equation:
y2 = 5
y1 = 7
x2 = 4
x1 = 8
Now, let's put these into the equation and solve:
[tex]slope = \frac{5 - 7}{4 - 8} = -\frac{2}{4} = -\frac{1}{2}[/tex]
Therefore, the slope is -1/2.

Sarah is going to the amusement park, where she has to pay a set price of admission and another price for tickets to go on each of the rides. 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?
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

The Nut House sells peanuts for $6.75 per pound and cashews for $9.50 per pound. On Saturday, they sold 32 pounds more peanuts than cashews. The total sales for both types of nuts was $1,012.25. Write and solve an equation to find the number of peanuts sold. Round your answer to the nearest whole pound.
Answer:
81 pounds
Step-by-step explanation:
Given that:
Peanut per pound = $6.75
Cashew per pound = $9.50
Let
Number of cashews sold = x
Number of peanuts sold = x + 32
Total sales made = $1,012.25
(Number of caahew sold * cost of cahew) + (Number of peanut sold * cost of peanut) = total sales made
(x * 9.50) + [(x + 32) * 6.75)] = 1012.25
9.50x + 6.75x + 216 = 1012.25
16.25x = 796.25
x = 796.25 / 16.25
x = 49
Number of peanuts sold = x + 32 = 49 + 32 = 81

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.

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)
