Answer:
If y = x then when x = -1 then y = -1
Step-by-step explanation:
Volumen carton= 64000 inches³
Volume of a candy box= 6 inx 5 inx 1/2
Volume of a candy box=15 inches³
Then, you have that the total candy boxes in the carton is:
x=640000 inches³/15 inches³
x=4267 candy boxes
About how many candy boxes are in the carton? There are 4267 candy boxes
1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.



1. m{t}°=64 m{I}°=58
2. This one is easy because algebra is the key.

Add like-terms.



x=5
The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
Answer:
Vertex is (-1, -9)
Step-by-step explanation:
To find the x-value of the vertex, we use the formula
x
=
−
b
2
a
(This is considered the axis of symmetry).
a
=
1
and
b
=
2
with
c
=
−
8
(These are the numbers in order)
By substituting we get
x
=
−
(
2
)
2
⋅
1
, which simplifies to
x
=
−
1
.
Once you find x, substitute back into the equation to find y.
y
=
(
−
1
)
2
+
2
(
−
1
)

y
=

y
=

Putting the two numbers together you get the coordinates
