Answer:

n=3 5/7

Step-by-step explanation:

8(n+7) Multiply each term in the parenthesis by 8

8n + 8 x 7

8n + 56

4 - 6n = 8n + 56

move variable to the left by adding its opposite to both sides

-6n - 8n + 4 = 8n - 8n +56

eliminate the opposites

-6n - 8n + 4 = 56

collect like terms by calculating the sum or difference of their coefficients

-6n - 8n

(-6 - 8)n

calculate the difference

-14n

divide both sides of the equation by -14

-14n / (-14) = 52 / (-14)

n = 52 / (-14)

n = -52/14

n= -26/7

alternative form of writing the answer is

n= -3 5/7 or n= 3.71429

yaroslaw [1]

Answer:

(a) Is not possible

(b) It is possible

(d) Is NOT possible.

Step-by-step explanation:

(a)

Is not possible, notice that for any function $g$ such that

$g : \mathbb{R} \rightarrow \mathbb{R}$

you would have that

$(g\circ f)(x) = g(f(x)) = g(|x|)$

And for, lets say -3,3 you have that

$g(|-3|) = g(|3|) = g(3)$ therefore is not possible to find a function that is one to one.

(b)

It is possible. Take the following function

$g(x) = x\sin(x)$ since $\sin$ is periodic it will take positive and negative numbers and if you multiply by $x$ each period will become bigger and bigger.

(c)

It is possible. Take the function

$g(x) = \sqrt{x}$

Then

$(f \circ g )(x) = | \sqrt{x} | = \sqrt{x}$ and $\sqrt{x}$ is one to one.

(d)

It is NOT possible because $(f\circ g)(x) = f(g(x)) = |g(x)|$ and that will always be positive.
