Keshawn is asked to compare and contrast the domain and range for the two functions.

Lapatulllka [165]

Answer: The correct option is 'The domain of both functions is all real numbers'.

Step-by-step explanation:

Here, functions are f(x) = 5x and g(x) =5x

Since the domain of f(x) is, D= { x : x belongs to all real numbers.}

Therefore, Domain of f(x) is all real numbers.

Since f(x) and g(x) have the same value,

Therefore, Domain of g(x) is also the set of real numbers.

Now, range of f(x) is , R= { 5x : x belongs to all real numbers.}

Therefore, Range of f(x) is all real numbers.

⇒ Range of g(x) is also all real numbers.

So, we can say by the above explanation, only option (1) is correct.

The product of 5 and the cube of x, increase by the difference of 6 and x3

lawyer [7]

Answer:

$4x^{3} +6$

Step-by-step explanation:

The product of 5 and the cube of x

$5*x^3\\\\=5x^3$

the difference of 6 and x^3

$6-x^3$

I understand as increase as sum so

$(5x^3)+(6-x^3)\\\\5x^3+6-x^3\\\\(5-1)x^3+6\\\\4x^3+6$

A student factors 10x^2+3x-27 to the following. (2x-3)(5x+9)

bearhunter [10]

Answer:

Step-by-step explanation:

The form (2x-3)(5x+9) is fully factored. To determine if it is equivalent, multiply the parenthesis out.

(2x-3)(5x+9) = 10x² - 15x + 18x - 27 = 10x² + 3x - 27

Yes this is equivalent.

The solution is A.

Which of the following options have the same value as 80% of 22?

Alex_Xolod [135]

80% of 22 can be written in the following ways:

1) 80% of 22 = 17.6

2) 0.8 x 22 = 17.6
The percentage is converted into decimal form.

3) 80/100 x 22 = 17.6
The percentage is converted into fraction form.

80/100 can be simplified to 4/5, and the point 3 can also be written as:

4) 4/5 x 22 = 17.6

Thus, following options have the same value as 80% of 22.
Option <span>A. 80/100 ⋅ 22
Option </span><span>D. 0.8 ⋅ 22
Option E. 4/5 ⋅ 22</span>
