Answer:
I got A= -2/5
Step-by-step explanation:
4a-3(a-2)=2(3a-2)
4a -3a -6=6a-4
1a-6=6a-4
-1a   -1a
-6=5a-4
+4 Â Â +4
-2 =5a
 5   5
A= -2/5
Hope my answer has helped you and if not I am sorry.
Answer:
a = 2
Step-by-step explanation:
4a - 3a + 6 = 6a - 4

-i  -  6i = -7i
Combine to get 1 -7i
Answer:
f-1(x) = (x+4) / 2
Step-by-step explanation:
given f(x) = 2x – 4
let y = f(x) and rearrange to express x in terms of y
y = 2x – 4  (add 4 to each side)
y + 4 = 2x (divide both sides by 2)
(y+4) / 2 = x (rearrange)
x = (y+4) / 2
f-1(y) = (y+4) / 2
hence
f-1(x) = (x+4) / 2
