The answer is a because it has a negative slope and to find it i did rise over run it rises one block for every four it goes over
Okay, so this is basically telling you that there is no solution. You don't have to worry about there being one. You just have to justify (or explain) why there isn't one.
Basically, neither y or x is equal to anything. You couldn't make x equal to a value in y because x and y are both together in the equation and equal to numbers.
We can always move a factor to the other side. So,
x-2y= -8
Add 2y to the other side.
x= -8+2y
Now, plug in -8+2y as x.
3(-8+2y)- 6y=-12
-24+6y-6y= -12
The 6y's cancel out. So, we can't figure out what y is.
-24=-12 <- no y.
These two lines are parallel. They have direct proportion in each other. That is why there is no solution because the lines never cross. Parallel lines do not cross.
I hope this helps!

The answer is 10.
4 a + 5 b when a = 4 and b = - 1.2
Answer: See explanation
Step-by-step explanation:
First and foremost, we should not that:
1 yard = 3 feet
We are informed that Wyatt uses 200 feet of rope for each doormat and that he wants to make 25 doormats.
The expression that shows a correct way to find how many yards of rope he needs will be:
= (200 × 25) / 3
= 5000/3
= 1666.67 yards
10 - 2x
10 - 2(7)
= 10 - 14
= -4
