Question

Given the function f(x)=9-2x, find x when f(x)=25 -41 17 -8

Answer 1

F(x)=9-2x move negative two over to f(x) and combine the two so it then becomes 3x then combine 9 and 25 and you get 34 then subtract f(x)to 3x and you get 2x and then divide 34 by 2x and you get 17

Answer 2

Answer:

x = -8

Step-by-step explanation:

Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:

9 - 2x = 25.

Isolate the -2x term by subracting 9 from both sides:

-2x = 16

Finally, solve for x by dividing both sides by -2:

x = -16/2, or x = -8
