Hello,
sin² x-cos² x=sin² x-(1-sin² x)=2sin² x-1
==============================
Answer:
The answer is C.24 - 9x3 - 8x2 + 15x
A. F(x)= 3x+6 =12
3x = 12-6
3x = 6
x=2
B. x=10, f(x)= 3*10+6 = 30+6 = 36
C. f(x) = 3x+6 = 6
3x = 6-6
3x=0
x=0
D. x=5, f(x) = 3x+6 = 3*5+6 = 15+6 = 21
Y = 2x + 2
Y = 2x -
Subtract
0 = 2
This makes no sense meaning the lines are parallel. Therefore there are 0 solutions.
