The second choice.................................
Answer:
no solution (parallel lines )=1/1=1/1=5/1
Step-by-step explanation:
trigonometric functions state that cosine functions are even so that automatically rules out the first two options.
sine functions are odd so the last two are right.
odd functions: f(-x)=-f(x)
so the sine would be: sin(-x)=-sin(x)
the third option should be the right answer

Answer:
-12
Step-by-step explanation:
−2.5+(−7.4)−(−1.2)−(+3.9)+(+0.6)
Subtracting a negative is adding
−2.5+(−7.4)+(1.2)−(+3.9)+(+0.6)
Combine like terms
-9.9 +(1.2)−(+3.9)+(+0.6)
-8.7-3.9+.6
-12.6+.6
-12
