That's the ratio of the ducks and chickens.
We don't know what ( 5 2 , 7 2 ) is supposed to represent, but it seems unlikely that the sum of those numbers is -6. Hence that is not a solution to the system.
The sum of -4 and 10 is +6, not -6, so that point is not a solution, either.
Neither offering is a solution to the equations.
When you have something to an exponent and the exponent is a fraction it basically means the numerator is the power of the number and denominator is the root of the number.
81^3= 531441
4 root (531441)=27
if you have a graphing or scientific calculator you should be able to enter straight in 81^(3/4).

Explanation:
The formula for calculating the sales price of an item is:
s
=
p
−
(
p
×
d
)
Where:
s
is the sales price: what we are calculating in this problem.
p
is the regular price of the item: $40 for this problem.
d
is the discount rate: 45% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 45% can be written as
45
100
.
Substituting and calculating
s
gives:
s
=
