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)

In a scale drawing, a rectangle has a length of 6.1 inches. The actual rectangle has a length of 85.4 inches.
Using proportions, it is found that the scale of the rectangle is of 1:14.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division to find the unit rates.
One example of application of proportions is for scale problems, as the scale is given by the following equation:
Scale = Drawn distance : Actual distance.
For this problem, we have that:
The drawn distance is of 6.1 inches.The actual distance is of 85.4 inches.Hence the scale is of:
6.1 : 85.4.
We can simplify dividing 85.4 by 6.1, hence:
85.4/6.1 = 14.
Hence the simplified scale is:
1:14.
What is the missing information?This problem is incomplete and could not be found on any search engine, hence we are going to suppose that it asks for the scale of the drawing of the rectangle.

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

a collection of 65 coins contains one with two heads. the remainder of the coins are fair. if a coin, selected randomly from the collection, turns up heads 6 times in 6 tosses, 1/65 is the probability it’s a two-headed coin
Definition of probability
(1) : the chance that a given event will occur. (2) : the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
We know that one coin in a collection of 65 has two heads. If a coin, chosen at random from the lot and then tossed, turns up heads 6 times in a row. We calculate the probability that it is the two-headed coin.
We calculate the number of possible combinations:
C₁⁶⁵= 65!/1!(65-1)!
= 65
Number of favorable combinations is 1.
Therefore, the probability is
P=1/65.

Step-by-step explanation:
Given quadratic equation:

Move the constant to the right side of the equation:
[tex]\implies x^2+2x-15+15=0+15[/tex]
[tex]\implies x^2+2x=15[/tex]
Step 2
Add the square of half the coefficient of the term in x to both sides to form a perfect square trinomial on the left side:

Work shown for part a)
density = mass/volume
density = (6775 kg)/(2.5 m³)
density = (6775/2.5) kg/m³
density = 2710 kg/m³
-----------------------------------
Work shown for part b)

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%

The equation y=0.74x+64 gives the cost y of renting a car if the car is driven x miles. Based on this equation, for every mile the car is driven the cost of increases by how much?
For every mile the car is driven the cost increases by $ 0.74 or 74 cents.
It is given in the question that the equation y = 0.74x + 64 gives the cost y of renting a car if the car is driven x miles.
It is a linear equation in 2 variable.
We have to find, for every mile the car is driven the cost increases by how much.
As we can observe from the equation, 64 is the fixed cost of renting a car, $ 0.74 is the cost of driving per mile.
Hence, for every mile the car is driven the cost increases by $ 0.74 or 74 cents.

The midpoint of the given coordinates of points (0,-10) and (-6,-8) is ( -3,-9 )
How determine the midpoint between two point?A midpoint is simply a point that divides a line segment into two equal halves.
The midpoint formula is expressed as;
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.
