Answer:
The system of the equations has no solution; the two lines are parallel
Step-by-step explanation:
we have
----> equation A
-----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
The lines does not intersect, the lines are parallel
see the attached figure
therefore
The system of the equations has no solution
Answer:
$212.50
Step-by-step explanation:
So you have to multiply 8.5 by 25 because for every hour she gets $25. And if she works for 8.5 hours then you multiply both numbers to get your answer.
Hope this helps!

Answer:
x=5, y=6
Step-by-step explanation:
7x+2y=47
5x-4y=1
to use elimination method , you want to add the two equations together so that either x or y cancels out. For these equations, we will multiply the first equation by 2. (This will cancel out y value)
2(7x+2y)=2(47)
14x+4y =94
————————
add above equation to second equation:
14x+4y=94 above equation
5x-4y=1 second equation
19x=95 added together
x=5
—————————————
‘solve for y by substituting x value (5) into either original equation
5x-4y=1
5(5)-4y=1
25-4y=1
-4y=-24
y=6
