minimum = 80
Q1 = 84
Q2 (median) = (85 + 86) / 2 = 171/2 = 85.5

80, minimum, is on outside of box (before Q1)......84 (Q1) is where box starts.....85.5 (median or Q2) is inside the box.....87 (Q3) is the end of the box......90, maximum, is outside the box (after Q3)
141 (The original number) ;1 + 4 + 1 = 6 (Add each individual digit together) ;6 is divisible by 3 ;Then 141 is divisible by 3 ;141 isn't a prime number ;In the same way, 171 is divisible by 9 ; then, 171 isn't a prime number ;
161 = 7 x 23; 161 is divisible by 7 ; then, 161 isn't a prime number ;
Test whether 171 is divisible by 2, 3 , 5 , 7 , 11 , 13 ( <span>an algorithm that tests each incremental </span>m<span> against all known primes < </span> division ) ;
but, 171 isn't divisibile by 2,3,5,7,11,13 ;
Finally, 171 is a prime number ;
Mixed Number Form: 6 11/45
Exact Form: 281/45
the answer is -12.
3+-3 is 6 and squared is 36 and divide that by -3 is -12
Answer:
The vertex is the point 
Step-by-step explanation:
we know that
The general form of an absolute value equation is
The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h, and k, tell us how far the graph shifts horizontally and vertically
The vertex is the point (h,k)
we have
Rewrite the expression (3x+1)
substitute
therefore
The vertex is the point
