So you can actually use a couple trig identities
tan(x-a) =(tan x-tan a)/(1+tan x*tan a)
From there, easy!
(tan x-tan a)/(tan x-tan a)/(1+tan x*tan a)
1/1/(1+tan x*tan a)
which is
(1+tanx*tana)
1+tan^2a
sec^2 a
typo, forgot the 1/1
Answer:
(-3,-4)
Step-by-step explanation:
Graph the line. Any point which falls within the shaded red of the graph is a solution. No points on the line since it is not equal to (its dashed) are solutions. Check the location of your points to verify that they fall within this area.
(-2,-3)---No
(-3,-4)---Yes
(0,-3)---No
(1,1)---No
you need to add the problem
