Each pound costs $1.19 .
So 15 pounds cost
(15) x ($1.19) = $17.85 .
Answer:
D
Step-by-step explanation:
-61>-10>0 is not true
The greater the negative number is the smaller it becomes.
Try this option:
the rule: if f(-x)=f(x), then the function f(x) is even, if f(-x)=-f(x) then the function is odd.
1. f(x)=-5x⁴-2;
if to substitute x→(-x), then f(-x)=-5*(-x)⁴-2; ⇔ f(-x)=-5x⁴-2, in other words f(x)=f(-x), it means that this function is even.
2. f(x)=x³+2x.
if to substitute x→(-x), then f(-x)=(-x)³+2*(-x); ⇔ f(-x)=-(x³+2x), in other words f(-x)=-f(x), it means that this function is odd.
Fist convert the equation to vertex form
y = 2(x^2 + 14x) - 8
y = 2 [(x + 7)^2 - 49] - 8
y = 2(x + 7)^2 - 106
So the vertex is at (-7,-106)
32 players = 16 matches ( 32/2)
16 players = 8 matches ( 16/2)
8 players = 4 matches (8/2)
4 players = 2 matches ( 4/2)
2 players = 1 match
16 + 8 +4 +2 +1 = 31 matches
