What is the slope of a line that is perpendicular to the line y=8x+5

statuscvo [17]

Answer:

-1/8

Step-by-step explanation:

Perpendicular slopes are negative reciprocals

The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.

Negative:

8/1--> -8/1

Reciprocal:

Flip the numerator and denominator

-8/1--> -1/8

So, the perpendicular slope of 8 is -1/8

Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type the answer exactly in this f

WINSTONCH [101]

We can get the inverse function by first setting f(x) = y, solving for x, and after that switching y and x. So, let's solve for x:
$f(x)= \frac{1}{2}x+4$
$y= \frac{1}{2}x+4$
$2(y-4)=x$
$2x-4=y=f (x)^{-1}$

Then, just plug in 4 for x, and solve:
$2(4)-4= f (x)^{-1}$
$4=f (x)^{-1}$

There you have your answer.
