Answer:
End behavior of a polynomial function depended on the degree and its leading coefficient.
1. If degree is even and leading coefficient is positive then


2. If degree is even and leading coefficient is negative then


3. If degree is odd and leading coefficient is positive then


4. If degree is odd and leading coefficient is negative then


(a)

Here, degree is even and leading coefficient is positive.


(b)

Here, degree is even and leading coefficient is negative.


(c)

Here, degree is odd and leading coefficient is positive.


(d)

Here, degree is odd and leading coefficient is negative.


Answer:
-2/3
Step-by-step explanation:
= 1/5 + (-2/3) = -7/15
(A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Rational number can be both positive and negative.)
Answer:
9
Step-by-step explanation:
use half the x coefficent and square it
x^2 − 6x + (-3)^2 = 10 + (-3)^2
x^2 - 6x + 9 = 10 + 9
(x - 3)^2 = 19
Make a proportion 20 miles/4 hours= 75miles/x. cross multiply gives you 20x=300. this will give you x = 15 hours
