Y = 2 - 4x input output
tester [92]

Every function is a rule which tells you how to associate inputs and outputs. The input, also known as independent variable, is often indicated with the letter x, while the output, also known as dependent variable, is often indicated with the letter y.

With this notation, we write y = f(x), read "y is a function of x", in the sense that the value of the variable y depends on the value of the variable x, and f is the function that tells you how y depends on x.

In your example, you have y = f(x) = 2-4x, which means "subtract four times the input (4x) from 2"

So, it doesn't matter which input you chose (i.e. the value for x), because you will always have to behave this way:

  • Pick an input value, x
  • Multiply it by four to get 4x
  • Subtract this number from 2: 2-4x

Here are some examples of explicit calculations: if I choose x = 2 and input, the workflow will be

  • Pick an input value, 2
  • Multiply it by four to get 8
  • Subtract this number from 2: 2-8=-6

So, if the input is 2, the output is -6

Similarly, if we choose x = 0 as input, we have:

  • Pick an input value, 0
  • Multiply it by four to get 0
  • Subtract this number from 2: 2-0=2

So, if the input is 0, the output is 2. And so on: for every possible value for x you have the correspondant value for y, with the function f telling you how to associate one with the other.

your bakery is in a large shopping center. The entrie shopping center is 4,500 square feet. Your bakery takes up only 1/10 of th
Kisachek [45]
So if the bakery is 1/10 of the shopping center's area, and the shopping center's area is 4500 feet, then the bakery's area is 1/10th of 4500 feet. 1/10th of 4500 feet is 450.

A more in-depth explanation:

A fraction is:
x/y
where y would equal how many parts you wanted to split a number into and x would equal how many parts you want to take.

So splitting 4500 into 10 parts and then taking one is basically 1/10 of 4500.

4500 in 10 parts, one would be 450.

Each person would get \frac{5}{8} pizza.

Solution:

Total quantity of pizza = 1\frac{7}{8}

Number of persons shared = 3

To find how much pizza would each person get:

Let us first convert  improper fraction into mixed fraction.

$1\frac{7}{8}=\frac{1\times8 + 7}{8}=\frac{15}{8}

Now divide the total quantity of pizza by the number persons shared.

$\text{Quantity of pizza each person get}=\frac{(\frac{15}{8}) }{3}

                                                    $=\frac{15}{8\times3}

                                                    $=\frac{15}{24}

Divide both numerator and denominator by 3.

                                                    $=\frac{15\div3}{24\div3}

                                                    $=\frac{5}{8}

Quantity of pizza each person get = \frac{5}{8}

Hence each person would get \frac{5}{8} pizza.
