Given f(x) = 3/4 x + 12, find the value of x when f(x) = x.

12345 [234]

Answer:

The rigth answer is, x = 1

Step-by-step explanation:

As:

f (x) = 3/4 x + 12

They separate the terms:

3/4 x = 12

Then, what you are multiplying happens to divide:

x = 12/1/3/4

Media are divided by means and ends with ends, and we have as a result that:

x = 3/3 = 1

Simplify the expression with using scientific notation (4 times 10 8)2

kifflom [539]

The scientific notation:

$a\cdot10^n\\\\1\leq a < 10;\ n\in\mathbb{Z}$

$(4\cdot10^8)^2=4^2(10^8)^2=16\cdot10^{8\cdot2}=16\cdot10^{16}\\\\=1.6\cdot10\cdot10^{16}=1.6\cdot10^{17}$

Used:

$(a\cdot b)^n=a^n\cdot b^n\\\\(a^n)^m=a^{n\cdot m}\\\\a^n\cdot a=a^{n+1}$

Answer: (4 × 10⁸)² = 1.6 × 10¹⁷

Match the solution set given in inequality notation with the solution set given in interval motion x > 7.8

Maslowich

Answer:

(7.8, ∞)

Step-by-step explanation:

Given the inequality :

x > 7.8 ; the inequality can be explicitly interpreted as x greater than 8 ; this means that the inequality holds for all values of x above 7.8

The interval for which the inequality holds true is :

x > 7. 8 - - - > (7.8, ∞)
