Infinite.

By solving for slope-intercept form you will find that these two equations produce the same exact line.

viva [34]

$f(x)=|x-4|\\
f'(x)=\text{sgn} (x-4)\\
\text{sgn} (x-4)=0\\
x-4=0\\
x=4\\\\

$

For $x$ $f'(x)$ .
For $x>4$ $f'(x)>0$ .
$\Downarrow\\
$
At $x=4$ there's turning point, which is equal $|4-4|=|0|=0$ .

What is the slope of a line perpendicular to the line whose equation is y = 2x+5?

zubka84 [21]

Answer:

slope = - $\frac{1}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 5 is in this form with slope m = 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$

Which of the following is another way to express the difference between -5 and 8?

dmitriy555 [2]

Answer: -5+8 because the difference (-) of -5 and 8 is 8 - (- 5) which can also be expressed as -5+8. All that matters is that 5 stays negative and 8 stays positive.

Ad libitum [116K]

Bianca is 4'12, cause brian is 4'6, brianna is 3 inches taller so thats 4'9, Bianca is 3 inches taller than Brianna so she is 4'12

Just add three each time, 6+3=9 9+3=12
