Write 80% as a decimal number and as a reduced fraction

Answers

Answer:

Decimal: 0.80      Reduced fraction: [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Take 80% and move the decimal two place values to the left.

This makes 0.80              (The decimal point is where the percent sign is.)

0.80 is [tex]\frac{8}{10}[/tex]  because the 8 is in the tenths place value.

[tex]\frac{8}{10}[/tex] can be simplified by dividing both the numerator and the denominator by 2.

[tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

What is function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x)=1/2x-3

Now, subtract 6 from the input of f to create a new function​ g

g(x)= 1/2x-3 -6

g(x)= 1/2x -9

and, multiply the input of function g by 4

h(x)= 4( 1/2x -9)

h(x) = 2x- 36

Hence, the value of h(x)= 2x- 36.
