Answer: C is correct, No solution
Step-by-step explanation:
Let’s simplify the second equation,
8x-4y=-20
We can divide the whole equation by 4...
8x/4-4y/4=-20/4
Which becomes....
2x-y=-5
Now let’s move things around to see if it’s the same equation as the one on top...
-y=-2x-5
y=2x+5
Now we need to solve the systems...
y=2x-5
y=2x+5
Since their slopes are both 2 and their y-intercepts are not identical, the answer is no solution. The two lines will continue on without ever crossing because they have the same slope.
Answer:
The other side = 
units
Step-by-step explanation:
A right triangle has a side of length 
units and;
the hypotenuse is 
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² = 
and c² = (
b² = c² - a²
b² = 
- 
= 
So b = 
= units.
So the other side = units.

You multiply 86 by 42.5 because each board is 42.5 and there are 86 boards.
Yes it will. For every one hour, the train travels 170 miles. That’s the rate of change/ the ratio-> 1:170
