195+1800=1995
Answer:

IN YOUR OWN WORDS How can you use function notation to represent a function? How are standard notation and function notation similar?
Standard Notation:
y = 2x + 5
Function Notation:
f ( x ) = 2x + 5
Please help, due tomorrow
Answer:
Step-by-step explanation:
N^2-10n+9
The function notation to represent a function is f(x) and standard notation and function notation are similar because y = f ( x).
What is function notation?Function notation is a way in which a function can be represented using symbols and signs. Function notation is a simpler method of describing a function without a lengthy written explanation. The most frequently used function notation is f(x) which is read as “f” of “x”. In this case, the letter x, placed within the parentheses and the entire symbol f(x), stand for the domain set and range set respectively.
What is domain?The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
According to the question
Standard Notation:
y = 2x + 5
Function Notation:
f ( x ) = 2x + 5
Function notation can be used to represent the function as it represent function using symbols and signs .
An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”;
that is, y = f ( x).
This last expression is read as “ y equals f of x” and means that y is a function of x.
Standard notation and function notation are similar because
An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”;
that is, y = f ( x).
Hence, function notation to represent a function is f(x) and standard notation and function notation are similar because y = f ( x).

Answer:
x= 4
Step-by-step explanation:
2x + 3( 5x - 7) = 47
2x + 15x - 21 = 47
17x -21 = 47
17x = 47 + 21
17x = 68
x = 68 / 17
x = 4
hope it helps plzz mark me brainliest
Answer:
X = 4 plz brainliest
Step-by-step explanation:
2x+3(5x-7)=47
Distribute
2x + 15x - 21 = 47
Combine like terms
17x -21 = 47
Add 21 to both sides
17x = 68
Divide by 17 both sides
X = 4
