Answer: A segment AB with Endpoints A (-8, 4) and B (2,4) is a horizontal line segment with (-3,4) as the midpoint.
A segment CD with endpoints C(-3,9) and D(-3,-1) will create a vertical line segment with (-3,4) as the midpoint.
A line segment FG with endpoints F (-6,0) and G(0,8) is a diagonal line with a slope of 4/3 and its midpoint is (-3,4)
Step-by-step explanation: For a horizontal or vertical line segment, choose the x-value or the y value of the midpoint. subtract 5 to get the lower endpoint, add 5 to get the higher endpoint. Keep the other coordinate the same.
The diagonal line segment is based on the hypotenuse of a triangle with side lengths corresponding to the Pythagorean Triple 3,4,5 Add and subtract 3 to the x-value od the midpoint, add and subtract 4 to the y value of the midpoint and the hypotenuses will extend 5 units in both directions from the midpoint.

Answer:
[tex]m = \frac{-1}{6}[/tex]
Step-by-step explanation:
You are solving for the slope (m). Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) =(-2 , 1)\\(x_2 , y_2) = (4 , 0)[/tex]
Plug in the corresponding numbers to the corresponding terms:
m = [tex]\frac{0 - 1}{4 - (-2)}[/tex]
[tex]m = \frac{-1}{4 + 2} \\m = \frac{-1}{6}[/tex]
[tex]m = \frac{-1}{6}[/tex] is your answer.

Step-by-step explanation:
A rectangular piece of cheese is 9 centimeters long is 5 centimeters wide. What is the perimeter
Solution:
We know that:
Perimeter of rectangle = 2L + 2BGiven:
L = 9 cmW = 5 cmSubstitute the values into the expression to find the perimeter.
Perimeter of rectangle = 2L + 2B=> 2(9) + 2(5)=> 18 + 10=> 28 cmAnswer: 28cm
Step-by-step explanation:
The perimeter formula for a rectangle = 2(l + w); where:
length = 9cm
width = 5cm
P = 2(l + w)
= 2(9 + 5)
= 18 + 10
= 28cm
Therefore, the perimeter of the cheese is 28cm

Identify the statement(s) that are both biconditional and false. Three points are not in the same plane if and only if exactly one line passes through them. Exactly one line passes through three points if the points are in an infinite number of planes. an infinite number of planes pass through the same three points if and only if the points are not on the same line. three points on the same line if and only if exactly one plane passes through them.
Answer:
Step-by-step explanation:
1) Three points are not in the same plane if and only if exactly one line passes through them.
It is biconditional and false because more than one plane can pass through three points
2)Exactly one line passes through three points if the points are in an infinite number of planes.
It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane
3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them
4). three points on the same line if and only if exactly one plane passes through them.
It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

Anna and Betty share 24 sweets in the ratio 3:5. How many sweets do they get each?
Answer:
Anna 9 and Betty 15
Step-by-step explanation:
sum the parts of the ratio , 3 + 5 = 8 parts
divide number of sweets by 8 to find value of one part of the ratio
24 ÷ 8 = 3 ← value of 1 part of the ratio , then
3 parts = 3 × 3 = 9
5 parts = 5 × 3 = 15
Anna gets 9 sweets and Betty gets 15
The volume of the shaded portion of the cylinder help??????????????
Answer:
56.52mm²
Step-by-step explanation:
Based on observation, sum of diameters of small circles = diameter of the big circle.
In question, diameter of big circle = 12 mm.
And radius of big circle = 12mm/2 = 6mm
Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.
=> 2a + 2a = 12mm
=> 4a = 12mm
=> a = 3mm
=> radius of each small circle = 3mm
Area of big circle = πr²
= (3.14)(6mm)²
= 113.04 mm²
Area covered by 2 small circles is: 2 * area of 1 one circle.
=> 2 * π(3mm)² = 18π mm²
=> 56.52 mm²
Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²
