WILL MARK BRAINLIEST!!!PLZ HELP!!!
Andrei [34K]

Answer:

Step-by-step explanation:

Hello,

<em>"Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only."</em>

We know that Kelsey is right, a polynomial of degree 3 has maximum 3 zeroes, so it means that the graph of this polynomial has maximum 3 x-intercepts.

<u>So how Ray can be right too?</u>

we need to think of y-intercept, if we add the y-intercept then Ray can be right too,

as you can see in one example below

there are 3 x-intercepts and 1 y-intercept.

This being said, Ray is not always right. For instance x^3

has only 1 zero (multiplicity 3) its graph has only 1 intercept in the point (0,0)

hope this helps

How do you write 9/10 as a decimal?
kykrilka [37]
Hey there! 

In order to turn a fraction into a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction. 

So, 
\frac{9}{10} as a decimal would be 0.9. Simply divide 9 by 10 

Answer: 0.9
