Answer:
Inconsistent
Step-by-step explanation:
we know that
If a system of two linear equations have at least one solution, it is said to be consistent .
If a consistent system has exactly one solution, it is independent .
If a consistent system has an infinite number of solutions, it is dependent .
If a system of two linear equations no have solution, it is said to be inconsistent.
Remember that
When solving a system of linear equations by graphing, the solution of the system is the intersection point both graphs
In this problem we have
----> equation A
----> equation B
Their slopes are equal (m=-2) and their y-intercept are different
so
we have two different parallel lines
The lines not intersect
therefore
The system has no solution, because is inconsistent
Answer:
say what
Step-by-step explanation:
I assume you mean, that an angle and two sides are known.
A formula that can be used for irregular triangles is the cosine rule.

'b' and 'c' must be sides that are beside the angle 'A' (angle opposite 'a').
Answer:
yes yes no no
Step-by-step explanation:
use the Pythagorean theorem. sub a^2+b^2=c^2.
c is the largest number, and you can plug the 2 other values into a and b.
