For triangle UTV reflection across y = 1 would be,
U' = (0, 2)
T' = (-3, 3)
V' = (-1, 5)
And for triangle HIJ the reflection across y = -2 would be,
H' = (-5, 1)
I' = (-3, -3)
J' = (-2, -1)
1)
In this question, we have been given a triangle UTV.
We need to find the the coordinates of the triangle if it is reflected across the line y = 1
Coordinates of UTV are:
U = (1, 2)
T = (-3, -1)
V = (-1, -3)
If we take the reflection across line y = 1 then,
U(1, 2) --> U'(0, 2)
T(-3, -1) --> T'(-3, 3)
V(-1,-3) --> V'(-1, 5)
2)
In this question, we have been given a triangle HIJ.
We need to find the the coordinates of the triangle if it is reflected across the line y = -2
Coordinates of HIJ are:
H = (-5, -5)
I = (-3, -1)
J = (-2, -3)
If we take the reflection across line y = -2 then
H(-5, -5) --> H'(-5, 1)
I(-3, -1) --> I'(-3, -3)
J(-2, -3) --> J'(-2, -1)
Therefore, for triangle UTV reflection across y = 1 would be,
U' = (0, 2)
T' = (-3, 3)
V' = (-1, 5)
And for triangle HIJ the reflection across y = -2 would be,
H' = (-5, 1)
I' = (-3, -3)
J' = (-2, -1)

The dependent variable is "Bonding of veneer to cabinets" and the independent variable is "a cabinet shop".
What is a Dependent variable?In mathematical modeling, statistical modeling, and experimental sciences, there are dependent and independent variables. Dependent variables get their name because, during an experiment, their values are investigated under the presumption or requirement that they are dependent on the values of other variables due to some law or rule. A test score, for instance, could be a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.So, in the given sentence, the dependent variable is "Bonding of veneer to cabinets" and the independent variable is "a cabinet shop".

On Gabriela’s first birthday, her parents gave her a $50 savings account. On every birthday after that her parents added to the account, increasing the amount they deposited by $25 each year. Complete the recursive definition for the sequence that represents this situation by finding the values for a1 and d.
We will see that the first term is $50, and the common difference is $25, then the recursive formula is:
aₙ = aₙ₋₁ + $25.
How to get the recursive formula?Here we will have something like an arithmetic sequence, such that the recursive sequence is something like:
aₙ = aₙ₋₁ + d
Where d is the common difference.
We know that the first value (the first amount that she has in her savings account) is $50, so we can write the first term as:
a₁ = $50
Now, each new year (the subindex "n" represents the number of the year) $25 are added to that savings account, then we will have:
a₂ = $50 + $25 = $75
a₃ = $50 + $25 + $25 = $100
And so on..
So the common difference is d = $25, then the recursive relation is:
aₙ = aₙ₋₁ + $25.

A 30cm 40cm page of a book includes a 2cm margin on each side, as shown. What percentage of the page is occupied by the margins
If a (30cm by 40cm) page of a book includes a 2cm margin on each side, then the margins occupy 11.67 percentage of the total surface area of one side of the pages.
As per the question statement, a (30cm by 40cm) page of a book includes a 2cm margin on each side.
We are required to calculate the percentage of the total surface area of one side of the pages, occupied by the margins.
To solve this question, first we will need to calculate the total surface area of one side of the pages, and also the surface area occupied by the margins on one side, and then simply, calculate the percentage amount between the two area values.
Since the dimensions of the pages of the book are (30cm by 40cm), therefore, area of one side of each page = (30 * 40) sq. cm.
= 1200 sq. cm.
And, area occupied by the margins on each side of the page
= [(2 * 30) + (2 * 40)] sq. cm.
= (60 + 80) sq. cm.
= 140 sq. cm.
Therefore, percentage of the total surface area of one side of the pages, occupied by the margins = [(140/1200) * 100] = 11.67%

M = ( (x₁+x₂)/2, (y₁+y₂)/2 )
Given the data in the question;
Point 1( 0,-10 )
x₁ = 0y₁ = -10Point 2( -6,-8 )
x₂ = -6y₂ = -8Midpoint = ?
To determine the midpoint, plug the given points into the midpoint formula above and simplify.
M = ( (x₁+x₂)/2, (y₁+y₂)/2 )
M = ( ( 0 + (-6) )/2, ( (-10) + (-8) )/2 )
M = ( ( 0 - 6) )/2, ( -10 - 8 )/2 )
M = ( ( -6 )/2, (-18 )/2 )
Midpoint M = ( -3,-9 )

fifteen dots are evenly spaced on the circumference of a circle. how many combinations of three dots can we pick from these 15 that do not form an equilateral triangle?
There are 450 triangles, we can pick that do not form an equilateral triangles when 15 dots are evenly spaced on the circumference of a circle.
Let's calculate the total no. of possible triangles, it depends on the combination. To make a triangle, we have to choose 3 dots out of 15.
Here, we will use the combination rule to find out the possible triangles,Thus, the total number of possible triangles = 15C3 = (15.14.13) / (1.2.3) = 455
Note that an equilateral triangle would be formed by connecting 3 equally spaced dots.
For an equilateral triangle, out of 15 dots, there would be 15 - 3 = 12 dots that will not be connected.
And 12/3 = 4 dots would be between any two connecting dots.
Taking 1st connecting dot, the second connecting dot would be
1 + 4 + 1 = 6th
Similarly, the third connecting dot would be 6 + 4 + 1 = 11th
So, the following connecting dots will form equilateral triangles: (1, 6, 11); (2, 7, 12); (3, 8, 13); (4, 9, 14); (5, 10, 15);
After applying the combination rule we found the total number of the possible triangle and there are 5 equilateral triangles:
So, there are 455 - 5 = 450 triangles that are not equilateral triangles.

3/5x + 1/4y=-1/2 slope intercept form
Answer: [tex]y= \frac{-12}{5}x -2[/tex]
Step-by-step explanation:
1) Move x to the right.
1/4y = -1/2 - 3/5x
2) Multiply both sides by 4 to make y by itself.
-1/2 * 4 = -2 (Multiply the top by 4 and you will get -4/2 = -2)
-3/5x * 4 = -12/5x (Multiply the top by 4 and you will get -12/5x)
y= -2 - 12/5x
3) Reorder the terms so that x goes first.
y= -12/5x -2
Answer: y=-12/5(x-2)
Step-by-step explanation:
Move x to the right.
1/4y = -1/2 - 3/5x
2) Multiply both sides by 4 to make y by itself.
-1/2 * 4 = -2 (Multiply the top by 4 and you will get -4/2 = -2)
-3/5x * 4 = -12/5x (Multiply the top by 4 and you will get -12/5x)
y= -2 - 12/5x
3) Reorder the terms so that x goes first.
y= -12/5x -2
