Answer:

x = 2 and x = 10

Step-by-step explanation:

(x+3)^2 = (x - 5)^2 + (x + 2)^2

x^2 + 6x + 9 = x^2 - 10x + 25 + x^2 + 4x + 4

x^2 + 6x + 9 =2x^2 - 6x + 29

x^2 - 12x + 20 = 0

(x - 10)(x - 2) = 0

x - 10 = 0; x = 10

x - 2 = 0; x = 2

What is the inverse of the function f(x)=4x+8
Leno4ka [110]

Answer:

f  ( x )  − 1  = ( 1/ 4  x )  − 2.

Step-by-step explanation:        

For inverse function, the x and y interchanges and then make y the subject again of the equation. See the working out below:

f  ( x )  =  4 x  +  8

 f  ( x )  =  y

y    =  4 x  +  8

 x  =  4 y  + 8  ----- interchanging  y  and  x

Now make  y  the subject of the equation:

x  =  4 y  +  8

 − 4 y  =  -   x  +  8

 y  =  ( − 1/ 4  ) .  −  x   +  ( − 1/ 4  )  .8

 y  =  ( 1/ 4  x )  − 2

So the inverse function is:

f (x)  − 1  =  ( 1/ 4  x )  − 2

Solve for x: 1 over 4 (2x − 14) = 4. 15 15 over 2 9 11
zloy xaker [14]
1/4(2x - 14) = 4....multiply both sides by 4
2x - 14 = 4 * 4
2x - 14 = 16
2x = 16 + 14
2x = 30
x = 30/2
x = 15 <==
