Answer:
1/2
Step-by-step explanation:
The Rational Root Theorem says that any rational root has
1. a numerator that is a factor of the constant term
2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)
Numerator: 
Denominator: 
That means there are only two possible rational roots: 
Try them both by plugging them into the polynomial.

Aha! The negative one-half value does not produce 0
Never seen this type of question but the bottom (4th last answer) makes the most sense
Answer:
4.05+4.05+12.9=21
Step-by-step explanation:
Take 21 subtract 12.9 first, then you take the leftover number which is 8.1 then divide it by 2 giving you 4.05.
Answer:
False
Step-by-step explanation:
The left side 0.8 does not equal to the right side -0.22, which means the given statement is false. Thank you and have a good day. Judging by this question, I presume that you are doing homework or classwork, and I wish you good luck.
Hello,
(x/(1/3))²-(y/(1/2))²=1 is an hyperbola.
y=0==>x=1/3 or x=-1/3 (-1/3,0) and (1/3,0) are x -intercepts
There are no reals y-intercepts.[(0,-i/2) and (0,i/2)]
