Step-by-step explanation:
lets separate z from each equation
2z=x-2y-2
4z=5x+2y+2
5z=-5y
so
z=x/2-y-1
z=5x/4+y/2+1/2
z=-y
lets use the first and third equation
we have z=-y we replace this z at the first equation
-y=x/2-y-1 so x/2-1=0
x/2=1
x=2
now we replace z=-y and x=2 at the second equation so
-y=5*2/4+y/2+1/2
-y/2-y=5/2+1/2
-3y/2=6/2
-3y/2=3
-y/2=1
y=-2
we know that z=-y
so z =-(-2)=2
finaly we have that
x=2 ,y=-2 ,z=2
Answer: 180
Step-by-step explanation:
If it gets reflected over the x-axis and then the y-axis, it would be in the opposite quadrant of it’s origin. A 180 degree rotation would give you the same result.
