I can see that 2 is a root but not 1? So I tried -1 by substitution and that works.
So to work out the 3rd root we just use the sum and product of roots theorem.
We have the sum of the roots = 11/7 and from there the third root is 4/7
C. This is because you have equal odds, so you are not leaning heavily in one direction!
Answer:
$1200
Step-by-step explanation:
According to the question,
$500 for airline ticket plus $100 each day .
Therefore, a seven day vacation would cost you $500 for the airline ticket plus $100 times seven days .
That is $500 + ( $100 x 7)
$500 + $700
$1200
