how to translate by the rule (x,y)->(x +6,y -3) then reflect image over the y axis
Transformation of Reflect image over the y axis for this equation (x ,y)->(x +6,y -3) is (3, -1)
Reflecting point (-6,1) on y = x
gives (1, -6)
Translating, (1, -6) by 2,5 is
(1 + 2, - 6 + 5) = (3, - 1)
Therefore, reflect image over the y axis translate by rule (x ,y)->(x +6,y -3) is (3, - 1)
transformation :A function, f, itself is called the transformation, i.e., f: X → X. After the transformation the pre-image X becomes the image X. This transformation can be any part or the mixture of operations such as translation, reflection, rotation and dilation. The translation is working a function in a particular direction, rotation is rotate the function to a point, reflection is the mirror image of the function, and dilation is the ascend of a function.
Translation, rotation, reflection, and dilation are the four most prevalent types of transformations. From the transformation, we have a rotation about any point, reflection over any line, and translation along any angle. The picture is congruent to its pre-image in these stiff transformations.. They are also called as isometric transformations. Dilation is performed at about any point of angle and it is non-isometric.
Rules for Transformations
Consider a function f(x). On a coordinate grid, we use the x-axis and y-axis to check the movement. Here are the rules for transformations of function that could be applied to the all graphs of functions. Transformations can be shown algebraically and graphically. Transformations are commonly found in algebraic functions. We can use the formula of transformations in graphical functions to obtain the graph just by transforming the fundamental or the parent function, and thereby move the graph around, rather than tabulating the coordinate values. We can visualize and learn algebraic equations with the aid of transformations.
Formula of Transformations
Let us consider the graph f(x) = [tex]x^{2}[/tex]
Suppose we have need to graph f(x) = [tex]x^{2}[/tex] -3, we shift the vertex 3 units down.
Suppose we have need to graph f(x) = 3 [tex]x^{2}[/tex]+ 2, we shift the vertex two units above and extend vertically by 3 factor
Suppose we have need to graph f(x) = 2(x-1)^2, we shift the vertex one unit to the right and extend vertically by 2 factor
Thus, we know the formula of transformations as
f(x) =a(bx-h) n + k
where k is the vertical shift,
h is the horizontal shift,
a is the vertical stretch and
b is the horizontal stretch

An angle measures 111.4° more than the measure of its supplementary angle. What is the measure of each angle?
The measure of the supplementary angles are 34.3 and 145.7 degrees.
What are supplementary angles?Supplementary angles are those angles that sum up to 180 degrees.
In other words, two angles are Supplementary when they add up to 180 degrees.
Therefore, the angles measures 111.4° more than the measure of it's supplementary angle.
Hence,
let
x = measure of the other angle
x + x + 111.4 = 180
2x + 111.4 = 180
subtract 111.4 from both sides
2x + 111.4 - 111.4 = 180 - 111.4
2x = 68.6
divide both sides by 2
x = 68.6 / 2
x = 34.3
Other angle = 34.3 + 111.4 = 145.7°
Therefore, the measure of the supplementary angles are 34.3 and 145.7 degrees.

Step 1 of 2 : How many different combinations of 4 movies can he rent?
Hector can have a total of 14950 number of combinations of 4 movies, from his shortlist of 11 documentaries and 15 foreign films, that he can rent.
As per the question statement, Hector has shortlisted 11 documentaries and 15 foreign films, from which he wants to rent any 4 movies.
We are required to calculate the total of number of combinations of 4 movies from his above mentioned shortlist.
Total number of movies Hector has shortlisted = (11 + 15) = 26.
That is, we will have to calculate the total of number of combinations of 4 movies, Hector can rent from a lot of 26 movies.
Now, we need to know the formula of combination which goes as [tex][nCr=\frac{n!}{r!(n-r)!} ][/tex],
When "r" objects are to be selected from a set of "n" objects, such that order of selection does not matter.
Here, (n = 26) and (r = 4), and using these values in the above mentioned equation of nCr, we get
[tex]26C4=\frac{26!}{4!(26-4)!} =\frac{26!}{4!*22!}=\frac{22!*23*24*25*26}{24*22!}=(23*25*26)=14950[/tex]
That is, Hector can have a total of 14950 number of combinations of 4 movies, from his shortlist of 11 documentaries and 15 foreign films, that he can rent.

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, the given expression is :
(-2 ¹/₂n + ¹/₄) + (3 ³/₄n - 5/8)
simplifying the above expression by taking like considering like terms :
= -2 ¹/₂n + 3 ³/₄n + ¹/₄- 5/8
= (15/4)n - (5/2)n + (2-5)/8
= (15-10)n/4 -3/8

The amount of the total rent is 120 dollars.
How to find the total rent using average?Four students plan to rent a minivan for the weekend and equally share the rental cost.
By adding one more people, they can each save $6.
Therefore, the 4 students equally share the rent.
Hence,
average for 4 student = total amount shared / number of student
average for 4 student = x / 4
When you add one more person,
average for 5 student = x / 5
Therefore, the difference, will give you the total amount of the rent.
x / 4 - x / 5 = 6
5x - 4x/ 20 = 6
x / 20 = 6

The circumference of the circle with radius 7 and value of pie 3, using the formula C= 2pie r is 42 unit.
Circumference of this circle using 3 for TT and 7 as radius.
The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference. There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.
Circumference of circle = π x Diameter of circle.
You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.
Here, π = 3, r = 7,
So C = 2*7*3 = 42 units.
