Answer:
B:J:S
6:8:10
6+8+10= 24 parts all together
Sarah has $50 and equals 10 parts. So, each part is worth $5. (50/10=5)
Thus, Ben receives 6 parts, with each part being $5. So, Ben gets $30. (6x5=30)
1) (-7)3
2) PEMDAS; simplify (5-3)
3) 5^3, 5x5x5 and 125
4) -8^4
5) 36
6) 7
7) -100
8) 30
There ya go! Pretty sure they're all right!
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

y
=

Putting the two numbers together you get the coordinates
