The answer is b I did this test yesterday
Answer:
1 is false
2 is true
3 is false
4 is false
Step-by-step explanation:
y-33=-2
y-33+32=-2+33
y=31
31=3x-2
31+2=3x-2+2
33=3x
33/3=3x/3
11=x
solution is (11,31)
graph of y=-3x-2... y=31 would be a horizontal line on 33 at the y axis
Answer:
-cot(x)
Step-by-step explanation:
tanx-(sec^2x / tanx)
Lets get a common denominator of tan
tan x * tan x/ tan -sec ^2 x/ tan x
tan ^2 x - sec ^2 x
---------------------------
tan x
We know than sec^2 - tan^2 =1 (trig identity) so factor out -1
-1(-tan ^2 x + sec ^2 x)
---------------------------
tan x
-1(1)
---------------------------
tan x
-1
----------
tan (x)
We know 1/ tan x = cot (x)
- cot(x)
