Hello,
sin² x-cos² x=sin² x-(1-sin² x)=2sin² x-1
==============================
Answer:
Step-by-step explanation:
If you meant to type x+1<21, then we simplify this inequality by subtracting 1 from both sides, ending up with x < 20.
I do not recognize what your "4" represents.
4 divided by 3 = a whole and 3 repeated more than 4 times
(to use the number 4)
:D
8 days because 4/5 = 8/10 and he is using 1/10 a day.
The slope of this line is -2.
rise/run
rise = 4
run = -2
4
------- = -2
-2
Using the points (1,0) & (0,2)
2 - 0 2
----------- = ----- = -2
0 - 1 -1
