Answer: All Real Number
Step-by-step explanation:
This is a system of equation, and generally, there are three ways to solve:
- elimination
- substitution
- augmented matrix
Here, we are going to use elimination
------------------------------------------------------------------------------------
Given
-2x-y=1
-6x=3y+3
Put them in the same order
-2x-y=1
-6x-3y=3
Multiply 3 on both sides for the first equation
-6x-3y=3
-6x-3y=3
We subtract the first equation from the second equation
0=0
The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.
Hope this helps!! :)

Answer:
14: B. 40 C. 40 D. 100
Step-by-step explanation:
a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100.
To double check just add 100+40+40=180
