Find the slope of a line that passes through the
following ordered pairs. Reduce to lowest
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.
I hope this helps!!

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

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.
I'm sorry if it has any wrong ♀️

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.
he table shows the amount of money raised by each region. The four regions raised a total of $ ( 5 . 38 × 10 4 ) . Region Amount Raised ($) East 1 . 46 × 10 4 North 2 . 38 × 10 4 South 6 . 75 × 10 3 West ? How much did the West raise? Express the result in scientific notation.
Answer: 8.65*103
Step-by-step explanation:
Using scientific notation, it is found that the amount raised by the West, in dollars, is of:
[tex]8.65 \times 10^3[/tex]
What is scientific notation?A number in scientific notation is given by:
[tex]a \times 10^b[/tex]
With the base being [tex]a \in [1, 10)[/tex].
Combined, the amount raised by the North, South and East is:
[tex]2.38 \times 10^4 + 6.75 \times 10^3 + 1.46 \times 10^4[/tex]
To add numbers, they need to have the same exponent, hence:
[tex]6.75 \times 10^3 = 0.675 \times 10^4[/tex]
To add the numbers, we add the bases and keep the exponents, hence:
[tex]2.38 \times 10^4 + 0.675 \times 10^4 + 1.46 \times 10^4 = 2.38 + 0.675 + 1.46 \times 10^4 = 4.515 \times 10^4[/tex]
The total amount is given in the problem, hence the amount raised by the West is:
[tex]5.38 \times 10^4 - 4.515 \times 10^4 = 0.865 \times 10^4 = 8.65 \times 10^3[/tex]

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.

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)

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?
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.

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.

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
