For each of the following claims, prove or disprove the claim:
(a) For the domain of all 3-digit numbers n, if the sum of the digits of n is divisible by 9, then n is divisible by 9.
(b) For natural numbers n, n² + n + 17 is always prime.

ok

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.

x=0.8898305 is the answer to that equation
