Answer:
A
Step-by-step explanation:
Remember that the x-value of the vertex when an equation is given in standard form can be found with the equation 
. So, we can take the coefficients from the equation and plug them in.
Now we know that the x-value of the vertex is 8. Next, the equation for the y-value is 
, where h is the x-value of the vertex (8).
So the vertex is (8,-1).
Finally, the axis of symmetry is the x-value of the vertex, also called h.
Final answer, vertex: (8,-1) and axis of symmetry: x=8
Hope this helps!
Answer:(1,1)
Step-by-step explanation:
y=4.5x
x=y/4.5
put value of x
y=4.5(y/4.5)
y=y
Answer:
one solution (-3, -6)
Step-by-step explanation:
the two line cross at the point (-3, -6) and only at that one point so there is only one solution (-3, -6).
Answer:
Perpendicular
Step-by-step explanation:
If you look at the image, it shows a rectangular prism. The line CD is next to the line AD. It is perpendicular because someone could draw a right angle where the lines CD and AD meet.
