Answer:
Step-by-step explanation:
{2x - 6y = 28
{−x - y = 14
−⅙[2x - 6y = 28]
{−⅓x + y = −4⅔
{−x - y = 14
____________
[Plug this back into both equations above to get the y-coordinate of −7];

Distance=rate times time
rate=xmiles per hour
time=y hours
total distance=distance1+distance2
distance1=45mph times 2=90mi
distance2=30mph times 3=90mi
total distance=90mi+90mi=180mi
total is 180mi

Answer:
Distance between two points calculator, formula, work with steps, step by step ... Distance between two points = √(xB−xA)2+(yB−yA)2 ( x B - x A ) 2 + ( y B - y A ) 2 ... theorem is used for measuring the distance between any two points A(xA,yA) ... for grade school students (K-12 education) to learn what is distance between ...

Answer:
The system has no solution.
Step-by-step explanation:
In order for the system to have a solution, both graphs must have an intercept to each others. We see in the picture that both graphs are parallel and do not have any interceptions which we don't know the solution to the system.
That means if graphs are parallel and have no interceptions, there are no solutions. The system of equations are for finding the interceptions of both graphs. But of course! Parallel lines do not intercept.
