given s(x) = 3x - 6 and t(x) = 6 - 3x.
find the simplified formula and domain for v(x) =(s/t)(x) and w(x)=(t/s)(x)
i have a few more if you want to plz message me : )

the y will be in still but your answer will be y x 3

step-by-step explanation:

jk: )

i want to die

what the hell man, i just want the points lol

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
