Cross multiply the expression so that we can get
(1+sinx)(1-sinx) = cos^2 x
1 - sin^2 x = cos^2 x
cos^2 x + sin^2 x = 1
since
cos^2 x + sin^2 x = 1
therefore
1 = 1
the two expressions are identical in a trigonometric sense
C is the answer. Hope this helps!
Answer:
Step-by-step explanation:
Let's get all of the terms with the on the right-hand side of the equation, and everything else on the left-hand side of the equation.
To do this, we should add to both sides of the equation to remove the from the left-hand side of the equation:
Finally, to get the by itself, we can divide both sides by :
Answer:
y=4-1/3x
Step-by-step explanation:
1/3x+y=4
y=4-1/3x
Answer:
x = 4
y =
Step-by-step explanation:
Ummmm
I'm not sure if this is corrrect but this is what I got
So first you solve 2x+4y=22 to find x
and you get x =
Then you have to subtitute for in
which you then get y=
After you have to subttitute y= for y in x =
which you get as x=4
Finally you get the answer as:
x = 4
y =
