(3,5) and (-1,2) --> positive slope
(-7,8) and (-7,0) --> undefined slope
Step-by-step explanation:
To find the slope of a function, we use the formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{rise}{run}[/tex] (rise/run)

Answer:
y = - [tex]\frac{1}{4}[/tex] x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line
m = [tex]\frac{-4+3}{4-0}[/tex] = - [tex]\frac{1}{4}[/tex]
Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = - [tex]\frac{1}{4}[/tex] x - 3 ← equation of line

Derek sent a chain letter to his friends, asking them to forward the letter to more friends. The group of people who receive the email gains 9/10 of its size every week and can be modeled by a function, P, which depends on the amount of time, t (in weeks).
Derek initially sent the chain letter to 40 friends.
Write a function that models the group of people who receive the email t weeks since Derek initially sent the chain letter
Answer:
Step-by-step explanation:
P(t)= 40*1.9^t/3
A function that models the group of people who receive the email t weeks since Derek initially sent the chain letter is p(t) =[tex]40 + 12t[/tex] (in t weeks).
What is a function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The number of people who received letters three weeks later:
= [tex]40 + \frac{9}{10} \times40[/tex]
= [tex]76[/tex]
The number of people who received letters one week later:
= [tex]40+(\frac{9}{10} \div3)\times40[/tex]
= [tex]52[/tex]
The number of people who received letters t week later:
= [tex]40+(\frac{9}{10} \div3).t\times40[/tex]
= [tex]40 + 12t[/tex]
So, a function that models the group of people who receive the email t weeks since Derek initially sent the chain letter is p(t) = [tex]40 + 12t[/tex] (in t weeks).

Answer:
The first one is a right triangle. The second one is C. (13,9)
Step-by-step explanation:
For each ordered pair, go over first, then up. For the first question, if all points are plotted, it makes a right triangle.
With the second question, the point must be the same distance from Q as P is already. That's 3 lines over and 7 lines up and down. It could stay at (__,9), so 3 spaces over is (13,9).
Ben and Roberto each own stores that sell video games. A) Ben’s Game World is having a sale on video games. The store is offering a sale pack of 4 video games for $43.80. What is the unit price of a video game in the sale pack? What would 7 games cost at Ben's Game World? B) Roberto’s Electronics is also having a sale on video games. The unit price of any video game at Roberto’s Electronics is 3/5 of the unit price of a video game in the sale pack at Ben’s Game World. How much would it cost a customer for 7 video games at Roberto’s Electronics?
Ben- unit price is 10.95
7 games= 76.65
Roberto- unit price is 6.57
7 games= 45.99
The unit price of a video game at Ben's Game World is $10.95, and 7 games would cost $76.65. Video games at Roberto's Electronics would cost $6.57 per game after applying the discount, with 7 games totaling $45.99.
Explanation:The student has asked for help with finding the unit price of video games in a sale at Ben's Game World and comparing this to the cost of video games at Roberto's Electronics. We are given that Ben is selling a pack of 4 video games for $43.80. To find the unit price, we divide the total cost by the number of games.
Calculate the unit price of a video game at Ben's Game World by dividing the total pack price by the number of games in the pack: $43.80 / 4 games = $10.95 per game.To find the cost for 7 games at Ben's game store, multiply the unit price by 7: $10.95 * 7 games = $76.65.Roberto's Electronics sells video games at 3/5 the price of Ben's unit price. First, calculate this discounted unit price: $10.95 * (3/5) = $6.57.To find the cost for 7 games at Roberto's store, multiply this discounted unit price by 7: $6.57 * 7 games = $45.99.A recipe for bread calls for 4 1/4 cups of flour.

Which statement is an important part of the proof of the converse of the Pythagorean
theorem?
A. It must be assumed that the Pythagorean theorem is true.
B. It must be assumed that the sum of the lengths of any two sides of a triangle are less than the length of the third one.
C. It must be assumed that the Pythagorean theorem is false.
D. It must be assumed that the sum of the lengths of any two sides of a triangle are greater than the eleventh of the third side.
To prove the converse of the Pythagorean theorem, it must be assumed that the Pythagorean theorem is true. This assumption is fundamental to the proof. Option A is correct answer.
The proof of the converse of the Pythagorean theorem.
To prove the converse of the Pythagorean theorem, it is important to start by assuming that the Pythagorean theorem itself holds true.
Therefore, option A is the correct answer: It must be assumed that the Pythagorean theorem is true.
This fundamental assumption is crucial since the converse states that if the sum of the squares of two sides of a triangle is equal to the square of the third side, then the triangle is a right triangle.
This is a direct implication assuming the Pythagorean theorem's validity.
An essential part of a mathematical proof, especially in geometry, involves using established theorems and logical deductions.
It's also worth mentioning Euclid's proposition that states, "Any two sides of a triangle are together greater than the third side." While this proposition is relevant to the properties of triangles, it is not a component of the proof for the converse of the Pythagorean theorem.

Circle o has a circumference of 42 pi
What is the length of the radius, r?
a. √21 cm
b. √42 cm
c. 21 cm
d. 42 cm
PLEASE HURRY!! I HAVE LIMITED TIME!! :)
Look at the attached picture⤴
Hope this will help u...
The length of the radius, r, is 21 cm. The correct answer is **c. 21 cm**.
Here's why:
- The circumference of a circle is calculated by the formula C = 2πr, where C is the circumference and r is the radius.
- We are given that the circumference of circle O is 42π.
Substituting the given value into the formula:
42π = 2πr
Dividing both sides by 2π:
r = 42π / 2π
Simplifying:
r = 21
Therefore, the length of the radius, r, is 21 cm.
Options a, b, and d are incorrect because they either involve taking the square root of the circumference directly (invalid formula for radius) or miscalculating the result of the division.
