Hi!
30 = x
f(x) = -1/5x - 14 find x when f (x) = -8
Set the equation equal to -8
-8 = -1/5x - 14
Add 14 to both sides.
6 = -1/5x
Multiply both sides by -5.
30 = x
Hope this helps! :D
Answer:
Step-by-step explanation:
You must have made a mistake
the point-slope equation y – 8 = 1/2 (x – 4)?
If so，res is f(x)=1/2 x+6
