Answer:
Step-by-step explanation:
Many ways to do this in the details.
All start by writing three equations with three unknowns
<em>-56 = a(3²) + b(3) + c</em>
-56 = 9a + 3b + c 1)
<em>-16 = a(-1²) + b(-1) + c</em>
-16 = a - b + c 2)
<em>-51 = a(-2²) + b(-2) + c </em>
-51 = 4a - 2b + c 3)
subtract equation 2 from equation 1
-40 = 8a + 4b
--10 = 2a + b
b = -10 - 2a 4)
subtract equation 3 from equation 1
-5 = 5a + 5b
-1 = a + b 5)
substitute 4 into 5
-1 = a + (-10 - 2a)
-1 = - a - 10
a = - 9
substitute a into 4
b = -10 - 2(-9)
b = 8
substitute a and b into any of 1, 2, or 3
-51 = 4(-9) - 2(8) + c
-51 = -36 - 16 + c
c = 1
y = -9x² + 8x + 1
We can use a plotting calculator to confirm our result.
Answer:
1.74 m
Step-by-step explanation:
8.7/5 =1.74
1.74 x 5 = 8.7 (proving equality)
Ana: 0.15(46) = 6.9 pages per day
Hillary: 0.11(72) = 7.92 pages per day
Roger: 0.12(68) = 8.16 pages per day
Juan: 0.14 (69) = 9.66 pages per day

Answer:
C. 452.16 in²
Step-by-step explanation:
Calculating for area of the pizza is the same as calculating for the area of the circle.
Area = πr²
Radius = 24 ÷ 2 = 12 in
Area = (3.14)(12)²
Area = (3.14)(144)
Area = 452.16 in²
Answer:If shoes are for all games in row, P
=
2
+
3
g
If not, P
=
5
g ,with g the number of games
Explanation:
The price depends:if shoes are included for the whole games, you just have to pay them once and then you have to pay
g
g
a
m
e
s
, so P
(
g
)
=
2
+
3
g Else, you have to pay g
s
h
o
e
s and g
b
o
w
l
p
a
r
t
y
,so
P
(
g
)
=
2g
+
3
g⇔
P
(
g
)
=
5
g
