Answer:  The correct option is

(1) The commutative postulate for multiplication

Step-by-step explanation:  We are given to select the correct postulate that is illustrated for the real numbers as follows :

6 . 12 = 12 . 6.

We know that

if a and b are any two real numbers, then the equality a . b = b . a illustrates the commutative postulate for multiplication.

So, if a = 6  and  b = 12, then we get

6 . 12 = 12 . 6.

Thus, the illustrated postulate is the commutative postulate for multiplication.

Option (1) is CORRECT.

Seven times a number minus the number is -48. Find the number.
irinina [24]
The answer is -8 I believe.

To put this into an equation, we get 7x-x=-48. This is equal to 6x=-48. When we divide we get -8.

F(x+1)+f(x+2)=2x+3; f(x)=?
Rama09 [41]

Answer:

F=\frac{-xf+f+2x}{x+1};\quad \:x\ne \:-1

Step-by-step explanation:

1. \mathrm{Subtract\:}f\left(x+2\right)\mathrm{\:from\:both\:sides}\\
F\left(x+1\right)+f\left(x+2\right)-f\left(x+2\right)=2x+3f-f\left(x+2\right)



2. \mathrm{Simplify}\\
F\left(x+1\right)=-xf+f+2x\\


3. \mathrm{Divide\:both\:sides\:by\:}x+1;\quad \:x\ne \:-1\\
\frac{F\left(x+1\right)}{x+1}=-\frac{xf}{x+1}+\frac{f}{x+1}+\frac{2x}{x+1};\quad \:x\ne \:-1

4. \mathrm{Simplify}\\
F=\frac{-xf+f+2x}{x+1};\quad \:x\ne \:-1

Final Answer: F=\frac{-xf+f+2x}{x+1};\quad \:x\ne \:-1
