Suppose A,B,C and D are different points on the same line. How many segments have endpoints at these points?
The number of line segments that can be formed on the same line is A = 6
What are Combinations?The number of ways of selecting r objects from n unlike objects is given by combinations
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
If A, B, C, and D are different points on the same line, then the number of line segments with endpoints at these points can be calculated by counting the number of ways to choose 2 points from the 4 points.
The number of ways to choose 2 points from 4 points is given by the binomial coefficient 4 choose 2, which is:
So , the combination is ⁴C₂
4 choose 2 = ⁴C₂ = (4!)/(2!(4-2)!) = (4 x 3)/(2 x 1) = 6
Hence , there are 6 line segments with endpoints at A, B, C, and D.

The number of tiles = 12b+38, where b is the number of bundles ordered
(a) If a customer needs 150 tiles, how many bundles will need to be ordered?
answer. Why do we need to round our answer up in this problem?
undles will need to be ordered? Explain how you got your
Step-by-step explanation:
Given the equation that represents this order expressed as;
The number of tiles = 12b + 38 where;
b is the the number of bundles ordered
If a customer needs 150 tiles, the total number of bundles ordered can be gotten by simply substituting The number of tiles into the modeled equation and find the value of b. This is as shown below;
On substituting;
150 = 12b + 38
12b = 150 - 38
12b = 112
b = 112/12
b = 9.33
b ≈ 9 bundles
We need to round up the problem because the number of tiles can not be in fraction but as whole numbers.
The inequality compare between two parameters with a certain extent. The number of bundles to be ordered are 10.
Given that:
Number of tiles the customer needs is 150.
Number of tiles supplier already has is 38.
Tiles per bundle is 12.
And we don't want to supply less tiles to the customer, that is why we will order equal or more tile bundles that will satisfy the customer's needs.
Let b be the number of bundles.
Or symbolically, using inequality, we can say that:
[tex]12\times b \: + 38 \geq 150\\\\b \geq \dfrac{112}{12}\\\\b \geq 9.333...\\[/tex]
Since bundles ordered will be counted in positive integers, thus we have:
b = 10
Thus, the number of bundles to be ordered are 10.

Which is a factor of 6x2 x − 7? x 1 2x 1 6x 7 3x 7
The factor of the polynomial 6x² + x − 7 using factorization is (x − 1) and (6x + 7). Then the correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The polynomial is given as 6x² + x − 7
On factorization, we have
6x² + x − 7
6x² + 7x − 6x − 7
x (6x + 7) −1 (6x + 7)
(x − 1)(6x + 7)

Solve for X. Show your work.
Answer:
x=9
Step-by-step explanation:
since the location of 4x+2 and 7x-25 is across from each other that means that they are equal to each other so you have to set them equal to each other by doing 4x+2=7x-25 then you add like terms you add 25 and 2 together which gives you 27 and the equation will look like 4x+27=7x and then you subtract 4x from 7x which gives you 3x and u get the equation 27=3x now you divide 27 by 3 and get 9 so the equation will be x=9

Item 12
SA−→ bisects ∠RST and m∠RST=54.2∘. Find m∠RSA and m∠AST.
Answer:
m∠RSA is 27.1° and m∠AST is 27.1°
Step-by-step explanation:
If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half the measure of this angle
In the given question
∵ Ray SA bisects ∠RST
→ That means it divides it into two angles RSA and AST
∴ m∠RSA = m∠AST = [tex]\frac{1}{2}[/tex] m∠RST
∵ m∠RST = 54.2°
→ Multiply its measure by to find the measures its parts
∴ m∠RSA = [tex]\frac{1}{2}[/tex] × 54.2°
∴ m∠RSA = 27.1°
∴ m∠AST = [tex]\frac{1}{2}[/tex] × 54.2°
∴ m∠AST = 27.1°

Shaun's parents agreed to pay 2/5 of the cost of a
bike, if he was able to save the rest. If his parents
gave him $92, how much did the bike cost?
Answer:
The bike was $230
Step-by-step explanation:
If 2/5 is $92 you can divide 92 by two like so,
92 ÷ 2 = 46
So ONE fifth is 46 to find out the total (5/5) you multiply by 5 so it would turn up like this,
46 × 5 = 230
The bike was $230

its a math question!!! please help! Find the image points given the following triangle reflected across the line y = -1
D(-1,-1), E(1,3), F(3, -2)
Question options:
D'(-2,-2), E'(0,-6), F'(2,-1)
D'(2,-1), E'(21,3), F'(0,-2)
D'(1,1), E'(-1,-3), F'(-3,2)
D'(-1,-1), E'(1,-5), F'(3,0)
Answer:
Step-by-step explanation:
Point D lies on the line, so it is invariant.
Point E is a distance of 4 units away from the line y=-1, so E is now (1, -1-4)=(1, -5).
By the same logic, F' is now (3, 0).
The image points of triangle reflected across the line y = -1 is D'(-1,-1) ,E'(1,-5) , F'(3, 0) .
What is image point?The given point P is "reflected" in the mirror and appears on the other side of the line an equal distance it. Drag the point P to see this. The reflection of the point P over the line is by convention named P' (pronounced "P prime") and is called the "image" of point P.
According to the question
Triangle points given
D(-1,-1), E(1,3), F(3, -2)
and reflected across the line y = -1
As, we have to reflect from y = -1 , there will be no change in x axis in image points only y axis will be change .
D(-1,-1)
x axis = -1
y axis = -1
x' axis = -1
y' axis = distance from -1 to -1 = 0
therefore,
y' axis = -1
D'(-1,-1)
E(1,3)
x axis = 1
y axis = 3
x' axis = 1
y' axis = distance from 3 to -1 = |3 -(-1 ) |= 4 unit
therefore, 4 unit form -1 in negative
y' axis = - 5
E'(1,-5)
F(3, -2)
x axis = 3
y axis = -2
x' axis = 3
y' axis = distance from -2 to -1 = |-2 -(-1 )| = 1 unit
therefore, 1 unit form -1 in positive
y' axis = 0
F'(3, 0)
Hence, the image points of triangle reflected across the line y = -1 is D'(-1,-1) ,E'(1,-5) , F'(3, 0) .
