Answer:
No solution
Step-by-step explanation:
The given equations are :
9x-3y=-6
3x-y=2.....(1)
5y=15x+10
5y-15x=10
or
y-3x=2 .....(2)
Equations (1) and (2) shows that the lines are parallel. We know that for parallel lines, there is no solution.
Answer:
The graph which shows the solution to the system of equations
y = 5x – 1
y = x + 3 is:
Graph D
Step-by-step explanation:
We are given system of equations:
y = 5x – 1
y = x + 3
on subtracting first equation by second, we get
0=4x-4
i.e. x=1
when x=1 y=4
Hence, solution of this system of equation is:
(1,4)
Which is represented by graph D
Answer:
