If f(x)= -6x+6 then f^-1(x)=

drek231 [11]

Recall that, to get the inverse relation of any expression, we start off by doing a quick switcharoo on the variables, then we solve for "y".

$\bf \stackrel{f(x)}{y}=-6x+6\qquad inverse\implies \boxed{x}=-6\boxed{y}+6
\\\\\\
x-6=-6y\implies \cfrac{x-6}{-6}=y\implies -\cfrac{x}{6}+1=\stackrel{f^{-1}(x)}{y}$

On a bicycle, Rosa rides for 3 hours and is 20 miles from her house. After riding for 5 hours, she is 32 miles away.What is Rosa

mel-nik [20]

Answer:

Rosa's rate is 6 miles per hour

Step-by-step explanation:

Rosa rides for 3 hours and is 20 miles from her house.

After riding for 5 hours, she is 32 miles away

Let x represents the number of hours

and y represents the number of miles away

(3,20) and (5,32)

rate is the slope

to find rate we find change in miles over change in hours

$slope =\frac{y_2-y_1}{x_2-x_1} =\frac{32-20}{5-3} =6$

so Rosa's rate is 6 miles per hour
