2cos^2 x = 1 + cos 2x
cos^2 x = 1/2(1 + cos 2x)
f(x) = 6cos^2 x - 4 sin 2x = 6(1/2(1 + cos 2x) - 4 sin 2x = 3 + 3cos 2x - 4sin 2x
First, set up the equation.
365x + 125 = 250x + 175
Second, combine like terms on the same side by subtracting 250x and 125 from both sides.
365x +125 = 250x + 175
-250x -125 -250x -125
__________________
115x = 50
Third, divide both sides by 115 to solve for x.
115x = 50
---- ----
115 115
Fourth, simplify.
x=50/115=10/23 or 0.435
Answer:
No Solution.
Step-by-step explanation:
Equality equation:
— 2y – Зу +8 = 8 — 5у – 12 (Given)
-5y + 8 = -4 - 5y (distributive property of equality)
-5y = -12 - 5y (subtraction property of equality)
= -12 (addition property of equality)
when you add 5y on both sides it cancels the 5y out, it's no solution.
