Answer:
Hence, the system of equation does not have solution.
Step-by-step explanation:
You have the following 2x2 system:
![x-2y=1\ \ \ \ (1)\\\\-4x+8y=-4\ \ \ \ (2)](https://tex.z-dn.net/?f=x-2y%3D1%5C%20%5C%20%5C%20%5C%20%281%29%5C%5C%5C%5C-4x%2B8y%3D-4%5C%20%5C%20%5C%20%5C%20%282%29)
You can obtain the solution to the system by using substitution method.
You solve the first equation for x:
(3)
Next, you replace (3) in the equation (2), and you solve for y:
![-4(1+2y)+8y=-4\\\\-4-8y+8y=-4\\\\0=0](https://tex.z-dn.net/?f=-4%281%2B2y%29%2B8y%3D-4%5C%5C%5C%5C-4-8y%2B8y%3D-4%5C%5C%5C%5C0%3D0)
The last result is the trivial solution. This means that the equation (2) is a multiple scale of the first equation. In fact, if you multiply equation (1) by -4, you obtain the equation (2).
Hence, the system of equations does not have solution.
X=-2 y=-1 these are x and y values

Answer:
answers B and E are true.
Step-by-step explanation:
(5,0) means x=5, y=0
the point of origin is (0,0) with x=0, y=0
therefore, A is wrong. yes, the point is 5 units to the right of the origin, but 0 (no) units up. and not 1.
B is therefore true.
C is therefore wrong.
D is wrong, because the point is to the right of y-axis (the vertical axis) and not on it.
E is true, because we go only to the right of the origin, but neither up or down. so, we stay on the x- axis (horizontal axis).
