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

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

Answers

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).

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Answer:

1,955 miles

Step-by-step explanation:

For this problem all we have to do is, assuming they were constantly going that speed and never stopped, multiply the items and the mph.

SO, to the airport is 65mph*3 hours, which would give 195 miles.

Then, To their destination, 450mph * 4hours = 1,800 miles

Now all that is left to do is add

195 + 1,800 = 1,995
