B. Add -12x to both sides. Then divide all terms by -2. The positive 12 on the right side will be a -6 and the -42 will be a positive 21. The inequality sign is always switched whenever the equation is divided by a negative number.

How do you do this problem?

PIT_PIT [208]

Answer:

Step-by-step explanation:

Let f(x) = 2x – 1

Substitute (x + b) in place of x.

f(x + b) = 2(x + b) – 1

= 2x + 2x –1

To find $\frac{f(x+b)-f(x)}{(x+b)-x}$ :

$\frac{f(x+b)-f(x)}{(x+b)-x}=\frac{(2x+2b-1)-(2x-1)}{(x+b)-x}$

$=\frac{2x+2b-1-2x+1}{x+b-x}$

$=\frac{2b}{b}$ (Cancel common term)

$=2$

Hence, $\frac{f(x+b)-f(x)}{(x+b)-x}=2.$
