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

Drag the tiles to the boxes to form correct pairs.
Match the pairs of equivalent expressions.
The pairs of equivalent expressions are:

(7/2b - 3) - (8 + 6b) --> -5/2b - 11
(-10 + b) + (7b - 5) --> 8b - 15
How to Determine Equivalent Expressions?Evaluate each of the given expressions in order to find out which expression is equivalent to each.
(-14 + 3/2b) - (1 + 8/2b) = (-14 + 3/2b) - (1 + 4b)
= -14 + 3/2b - 1 - 4b
= -15 - 5/2b
(5 + 2b) + (2b + 3/2) = 5 + 2b + 2b + 3/2
13/2 + 4b
4b + 13/2
(7/2b - 3) - (8 + 6b) = 7/2b - 3 - 8 - 6b
-5/2b - 11
(-10 + b) + (7b - 5) = -10 + b + 7b - 5
= -15 + 8b
= 8b - 15
Thus, the pairs of equivalent expressions are:
(-14 + 3/2b) - (1 + 8/2b) --> -15 - 5/2b
(5 + 2b) + (2b + 3/2) --> 4b + 13/2
(7/2b - 3) - (8 + 6b) --> -5/2b - 11
(-10 + b) + (7b - 5) --> 8b - 15

Apple weights in an orchard are normally distributed. From a sample farmer Fred determines the mean weight of a box of apples to be 270 oz. with a standard deviation of 10 oz. He wonders what percent of the apple boxes he has grouped for sale will have a weight less than 255 oz.
Carl calculates the z-score corresponding to the weight 255oz= -1.5.
Now, Carl decides to find the percent associated with boxes less then 255 oz, so he rounds to hundred and substract 50% - 7% = 43%.
Given that,
In an orchard, apple weights are typically distributed. Fred the farmer concludes from a sample that the average weight of a box of apples is 270 ounces, with a standard deviation of 10 ounces.
He is interested in knowing what proportion of the apple boxes he has gathered for sale will weigh less than 255 oz.
Mean is 270
Standard deviation is 10
x = 255
Formula for z-score,
z = (x - mean)/SD
z = (255 - 270) / 10
=> z = -15 / 10
=> z = -1.5
Hence, by using z-table,
-1.5 equates to 0.0668, which suggests that 0.07
Therefore, 7% of Apple boxes weigh less than 255 oz.
The ratio of boxes is between 255 oz and 270 oz,
Calculating the proportion
Now,
50% - 7% = 43%.
Therefore, Carl calculates the z-score corresponding to the weight 255oz= -1.5.

The cost to send a letter that weighs 5 ounces is $11.75.
Flat rate = $8.00
Charges on every ounce = $0.75
Given equation :
y = 0.75x + 8.00
'y' = Cost of the postage
'x' = Weight of the letter in ounces
According to the question we can determine the cost of mailing a letter with the help of given equation (y = 0.75x + 8.00).
We have given that the weight of letter that need to send is 5 ounces.
So, x = 5
Lets find the cost of postage,
y = 0.75x + 8.00
y = (0.75 × 5) + 8.00
y = 3.75 + 8.00
y = $11.75
Hence, it will take $11.75 to mail a letter or we can say cost of postage.

Using linear function concepts, it is found that this doubling property does not hold for every linear relationship.
What is a linear function?A linear function is modeled by:
y = mx + b

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.One example of function is:

When x = 1:
y = 4 + 3 = 7.
When x = 2:
y = 8 + 3 = 11.
