The answer to this question is A
Step-by-step explanation:
first of all
put above of equation
(sin/cos)(sin)+cos =sec
sin²/cos +cos=sec
take l.c.m
sin²+cos²/cos=sec
as sin ²+cos²=1 so
1/cos=sec
sec=sec
hence proved
Answer:
3x-6=2x x=6
Step-by-step explanation:
3x-6=2x
-6=2x-3x
-6=-x
6=x
Answer:
The inequality representing the shaded area is y < 3 - 2.5·x
Step-by-step explanation:
The given equation of the graph is 5·x + 2·y = 6
Therefore, we have;
2·y = 6 - 5·x
y = 6/2 - 5/2·x
y = 3 - 2.5·x
Given that the graph is represented by a shaded region on the left and lower side of a broken line, the inequality relationship for the graph is that of a lesser than area inequality with a symbol of < and the inequality for the graph can be represented as follows,
y < 3 - 2.5·x.
