In this given graph, f(x) is a polynomial modeling the Pi-guy, the math superhero, flying around. Write an equation in terms of
saw5 [17]

Answer:

The given transformation are;

1) Parent function = f(x)

2) Transformation A = f(x + 5)

3) Transformation B = f(x) + 3

Step-by-step explanation:

1. The question being asked in the problem is the representation of the transformation of the given figure which is a function (the curved line that runs through the hands of Pi-guy in the drawing) in functional notation using f(x) to represent the function

2. Try using changes along the x axis as changes in the independent variable, x, in the function f(x) as follows;

Initial position of the parent function = f(x)

Transformation A, which is a translation, 5 units to the right along the x axis = f(x + 5)

Transformation along the y-axis where x = 0, as addition or subtraction to the parent function

Therefore;

Transformation B, which is a translation, 3 units to the up along the y-axis with x at 0 = f(x) + 3

3. The outline of the answers can be presented as follows

The given transformation are;

1) Parent function = f(x)

2) Transformation A = f(x + 5)

3) Transformation B = f(x) + 3

4. The above expression can be checked by considering the curve of the function as a figure and performing the given translations on all points on the figure

A shop sells fruit in two types of gift boxes: standard and deluxe. Each standard box contained 1kg of peaches and 2kg of apples
Morgarella [4.7K]
Let's call the number of standard boxes sold x and the number of deluxe boxes sold y.
The kg of peaches sold will be 1 for each standard box and 2 for each deluxe, so we know:
x + 2y = 12
The kg of apples sold will be 2 for each standard box and 1.5 for each deluxe, so:
2x + 1.5y = 14. Now we solve the two equations as a system:
From the 1st one:
x = 12 - 2y
We substitute in the second one:
2(12 - 2y) +1.5y = 14;
24 - 4y +1.5y = 14;
-2.5y = -10;
y = 10/2.5 = 4;
Now we substitute in the first equation:
x = 12 - 2y = 12 - 2*4 = 12 - 8 = 4.
So the shop sold 4 standard boxes (x) and 4 deluxe boxes (y).

Two numbers are in the ratio 2:3 and their sum id 45 then find both numbers​
iragen [17]

Let the numbers be 2x and 3x.

<u>According to the Question</u>,

⇒ 2x + 3x = 45

⇒ 5x = 45

⇒ x = 45/5

⇒ x = 9

<u>Now finding the values of both the number,</u>

⇒ 2x = 2 × 9

= 18

⇒ 3x = 3 × 9

= 27

<u>Hence, the value of both the number is 18 and 27 respectively.</u>
