Answer:
-1
Step-by-step explanation:
5 to the 2nd power is the same as 5 times 5... so, 24 - 25 is -1.
Step-by-step explanation:
To prove :
( 1 - sin x ) ( 1 + sin x ) = sec² x
LHS : -
( 1 - sin x ) ( 1 + sin x )
Formula / Identity : -
( a - b ) ( a + b ) = a² - b²
Here,
a = 1
b = sin x
( 1 - sin x ) ( 1 + sin x )
= 1 - sin² x
Identify : -
sin² θ + cos² θ = 1
cos² θ = 1 - sin² θ
Similarly,
1 - sin² x
= cos² x
= RHS
Hence verified.

-y - 718 + 11y413 - 77y412
Answer to your question
No y=mx+b your missing the b in the formula which stands for y intercept
