Answer:
-1 x - 2
f (x) = -----------
3
Step-by-step explanation:
Then we have y = 3x + 2.
Next, interchange x and y, obtaining x = 3y + 2
Next, solve this result for y: 3y = x - 2; then divide both sides by 3:
y = (x-2)/3
Last, replace "y" with the inverse function label:
-1 x - 2
f (x) = -----------

<span>a || b
4x + 72 + 2x - 12 = 180
6x + 60 = 180
6x = 180 -60
6x = 120
x = 120/6
x = 20</span>
First you to eliminate i from denominator.
mult by (7+3i) above and below
=(49+42i-9)/(49-9)
which is (40+42i)/40 which can simplify
B
Because 2 sqrt5 is = to sqrt 20.
4^2=16, 6^2=36
The third one is the answer but i may be wrong
