Answer:
infinitely many solutions
Step-by-step explanation:
We want to find solution to the system:
-4y=-20x+40
y+10=5x
We make y the subject in the second equation to get;
y=5x-10
We substitute y=5x-10 into the top equation to get:

We expand to obtain;

This implies that:

Therefore the system has infinitely many solutions.

The correct answer is parallel
Answer:

Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n
The side opposite to 60 degree angle: 
The side opposite to 90 degree angle: 2n
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x =
