We will assume that the number is n
one eighth of the number = 1/8 x n = n/8
we know that this result n/8) is less than or equal (<=) 3
therefore, the inequality is:
n/8 <= 3
The given quadratic expression; 5b² -6b -2 is prime because the discriminant is not a perfect square.
<h3>
What is the discriminant of the expression?</h3>
According to the task content; it is required to identify if the expression is prime.
On this note, it follows that the discriminant of the expression can be evaluated as follows;
= 36 -(4× 5 × -2)
= 76.
Hence, the expression is prime since 76 is not a perfect square.

The range is the y values that can be gotten from inserting the domain
we will assume the domain to be all real numbers
when x approahces infinity, y approaches inifnity
when x approaches negative inifnity, y appraoches negative infinity
no holes
range is all real numbers
A1 is the 1st term
r is the difference, they can say "r" or "d" for the difference
1st a1 is the first term = -3
2nd "r" is the difference between each consecutive terms (coming after each other) = 1.5
the rule to get any term of the sequence as we add 1.5 each time is --> a1+(n-1)*d
a1 --> 1st term , n --> order of the term u want whether 2nd, 3rd , 25th
d --> difference
so to get the 2nd--> -3+(2-1)*1.5= -1.5
to get the 3rd --> -3 +(3-1)*1.5 = 0

Y = 2^x
For a 64 team tounament, 64 = 2^6, so there will be six rounds of play.
For a 128 team tounarment, 128 = 2^7, so there will be 7 rounds of play.
Any number of teams which is not a power of 2 is an inappropriate number of team for tounament play.
