ANSWER
4 roots.
EXPLANATION
The given polynomial function is

This is a fourth degree polynomial.
According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.
This roots include both real and complex roots.
Also repeated roots or roots with multiplicity greater than one are counted as distinct.
Since the given polynomial function is a fourth degree polynomial, the Fundamental Theorem of Algebra, says that this polynomial has 4 roots.
The equation that best represent the actual prices of the skis is,
I x - 500 I ≥ 250
Solving the absolute value equation,
x ≤ 750 and x ≥ 250
Thus, the prices of the skis ranges from 250 to 750.
So, to turn this into a percentage, we have to turn this into a decimal by dividing:
80/100 = 0.80
80% of tart cherries are produced in this state.
Answer:
x-30y=100 and 10y=x-20
Step-by-step explanation:
I would say the third one would be the correct or the second one
