The option that is the best buy is option 3.
<h3>What is the best buy? </h3>
The best buy is the option that has the lowest average cost. Average cost is the total cost of the bottles divided by the number of bottles.
Average cost = total cost / number of bottles
Option 1: $8.75 / 5 = $1.75
Option 2: $5.97 / 3 = $1.99
Option 3: $6.36 / 4 = $1.59
Option 4: $12.60 / 7 = $1.80

Answer:
x = - 2.5
Step-by-step explanation:
Given that the sketch represents
y = x² + bx + c
The graph crosses the y- axis at (0 , - 14), thus c = - 14
y = x² + bx - 14
Given the graph crosses the x- axis at (2, 0), then
0 = 2² + 2b - 14
0 = 4 + 2b - 14 = 2b - 10 ( add 10 to both sides )
10 = 2b ( divide both sides by 2 )
b = 5
y = x² + 5x - 14 ← represents the graph
let y = 0 , then
x² + 5x - 14 = 0 ← in standard form
(x + 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2
The x- intercepts are x = - 7 and x = 2
The vertex lies on the axis of symmetry which is midway between the x- intercepts, thus
the x- coordinate of the turning point is
=
= - 2.5
Answer:
1.5/8 of the bag
Step-by-step explanation:
1/4 * 2 = 2/8
----------------------
3/8 + 2/8 = 5/8
1 - 5/8 = 3/8
3/8 divided by 1/2 = <u>1.5/8</u>
Object a:
perimeter is all the sides added together!
9+9=18
4.1+4.1= 8.2
18+8.2=36.2
object A’s perimeter is 36.2 CM
————————————————————
object b:
7.2+3+ 3.6= 13.8
object B’s perimeter is 13.8 CM

hope this helped! xoxo
C.
y - 65 = -10(x - 6)
is what i say it is but im not for sure, so sry if im wrong.
