Answer:
I believe your answer would be C
Answer:
C. 9
Step-by-step explanation:
it's multiple choice so plug each value in
A = -26
B = -34
C = 22
D = 46
so the answer is c
The answer is. A) y=-4/5x-7
Just compare, and they will equal each other.
<u>Answer and explanation</u>
(1+sinθ)(1-sinθ)=cos²θ
We are to prove that the left hand side is equal to the right hand side.
(1+sinθ)(1-sinθ) = 1(1-sinθ) + sinθ(1-sinθ)
= 1 - sinθ + sinθ - sin²θ
= 1 - sin²θ
From the trigonometric identity sin²θ + cos²θ = 1,
1 - sin²θ = cos²θ
