Answer: Number one would be 3x+2y+-14 and x+y=-4, second one is x=-3, y=7
Step-by-step explanation:
The first one is solved by inputting the x and y in each one and finding which one comes out true, the second on is solved by substitution. to find x you would subtract x in the first equation and make it y=4-x then input that equation in the y in the second equation.
Answer:
thethe answer is the 3rd one
Equate whats inside (arguments) 
with base period of sine function 
and solve for x to get period,
So the period of the graph of the given function is precisely 2.
Hope this helps :)
