Hello from MrBillDoesMath!

Answer:

y >= 8

Discussion:

The equation

y - 16 > = -8 => add + 16 to both sides

y - 16 + 16 > = -8 + 16 =>

y >= 8

NOTE: in your figure you show y > 8. That is NOT correct as it excludes the point 8 which is a valid solution. Similarly your graph shows an open circle (for not included, for x = 8). That should be a FILLED circle as x= 8 is included in the solution set. Get it? You had the solution but for some reason you incorrectly excluded x = 8.

Thank you,

MrB

Which number is a prime number? 141 161 171 151

Law Incorporation [45]

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 ( an algorithm that tests each incremental m against all known primes < division ) ;
but, 171 isn't divisibile by 2,3,5,7,11,13 ;
Finally, 171 is a prime number ;
