Answer:
We can not see all the graphs, so i will just do a graph of the system of inequalities, and you can select the option that matches it.
We have the system:
y ≥ 2x + 1
(to represent this, we need to have a solid line y = 2x + 1, and shade all the region above this)
y ≤ 2x - 2
(to represent this, we need to have a solid line y = 2x - 2, and shade all the region below this)
The graph of this system is shown below:
Answer:
A
Step-by-step explanation:

as 0≤θ≤90
so θ/2 is also in 0≤θ≤90
hence sin θ/2 and cos θ/2 are positive.
Answer: 3(4+6+7)
Explain: greatest common factor of the 3 numbers is 3. After you get 3 out of the 3 numbers, you will end up with 3(4+6+7)
