6 0
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7

Round Ed to the nearthest tenth and answer now question
Vikki [24]

Answer:

y = 9.1

Step-by-step explanation:

y can be found using the Law of sines as explained below:

m < Y = 106°

m < X = 58°

WY = x = 8

WX = y = ?

Thus,

\frac{x}{sin(X)} = \frac{y}{sin(Y)}

\frac{8}{sin(58)} = \frac{y}{sin(106)}

\frac{8}{0.848} = \frac{y}{0.961}

Multiply both sides by 0.961 to solve for y

\frac{8}{0.848}*0.961 = \frac{y}{0.961}*0.961

\frac{8*0.961}{0.848} = y

\frac{8*0.961}{0.848}*0.961 = y

9.07 = y

y = 9.1 (to the nearest tenth)

What percent of 20 is 6
Luba_88 [7]

Answer:  30 percent of 20 is 6.

_______________________________________________

Step-by-step explanation:

_______________________________________________

(n/100)  * 20 = 6  ?  

Solve for "n"  .

_______________________________________________

Divide each side of the equation by "20" :

{ (n/100) * 20 }  / 20  = 6 / 20 ;

to get:

n/100  = 6/20 ;  

↔ 6/20 = n/100 ; solve for "n" ;

Look at the denominators:


20 * ? = 100 ?

  100/ 20 = ?  ;

  100/20 = 5 ;


So, 20 *  " 5" = 100 ;

Then 6* 5 = "n"  (for the numerator, "n";  in  :   "n /100" ) ;

                  →  6 * 5 = 30 ;

                  →  n = 30 .

_______________________________________________

 Answer:  30 percent of 20 is 6.
