Answer:
x
=
5 and (
5
,
−
9
)
Explanation:
The equation of a parabola in vertex form is.
2
2
y
=
a
(
x
−
h
)
2
+
k
2
2
Where (
h
,
k
) are the coordinates of the vertex and a is a multiplier
f
(
x
)
=
(
x
−
5
)
2
−
9 is in this form
with (
h
,
k
)
=
(
5
,
−
9
)
⇒
vertex =
(
5
,
−
9
)
the axis of symmetry passes through the vertex is vertical with equation
x
=
5
← axis of symmetry graph{(y-x^2+10x-16)(y-1000x+5000)=0 [-20, 20, -10, 10]}
This isn't a valid answer but that looks alot like a Parcc test. Are you cheating?And it's .0318 %
Answer:
20/36 = 5/9
Step-by-step explanation:
The fraction could be represented by ( # of pages that typed / # of total pages that has to type).
So
20 is number of pages that typed
36 is the total number of pages that has to types
20/36
