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.
Answer:
s = the price of a silver ticket
g = the price of a gold ticket
s = 7 + (1/2)*g (first relation)
s = (6/5)*g - 14 (second relation)
but (first relation) = (second relation) so we get
7 + (1/2)*g = (6/5)*g - 14
(6/5)*g - (1/2)*g = 7 + 14
(7/10)*g = 21
g = 30
from (first relation) we get s = 7 + (1/2)*30 = 22.
how much would someone save? the answer is g - s = 8.

Answer:
1010a
Step-by-step explanation:
Mathematically, when a number is raised to a fraction, it simply means we are to find the root of that number to the denominator of the given fraction
For example;
100,000^1/5
= 5 x√((100,000) = 10
Likewise;
1,000,000^1/2 = √(1,000,000) = 1000
Thus, we have it that;
10 * a + 1000 * a
= 10a + 1000a = a(1000 + 10) = 1010a
