See the attached picture:
X = 9
Answer:
verticle
you are correct
Step-by-step explanation:
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
Where (
h
,
k
) are the coordinates of the vertex and a is a multiplier
f
(
x
)
=
(
x
−

−
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]}
She knits 18 squares on Monday.
Then she knits 7 more squares each day:
Tuesday: +7, Wednesday: +7, Thursday: +7 and Friday: +7
18 + 7 * 4 = 18 + 28 = 46
Answer: She has 46 squares on Friday.
