Answer: D
Step-by-step explanation:
trust me
Answer: c
Step-by-step explanation:
It can be b), c) and d).
b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.
c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.
d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.
a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)

Answer: All points in the shaded region after 2y<-12x+4 is the solution.
Step-by-step explanation:
Since we have given that

We need to find the point of solution to the system of inequalities:
Suppose

We first check the consistency of the system of equation:

So, it is parallel system of equations, but we consider it as an inequality, so all the points in the shaded region is the solution.
Using zero test,

0<4 it is true so, shaded part is towards the center.
Similarly,

0<4 again it is true it would be shaded towards the center.
So, the common part will be after 2y<-12x+4 .
Hence, all the points in the shaded region is the solution.
