If d=6, there are two real solutions.
Rule if d=discriminant:
d>0, two real solutions
d=0, one real solution
d<0, no real solutions (but there are two imaginary solutions)
26. Given
#2. Theorem: Vertical angles are congruent.
#3. Theorem: Congruence of angles is transitive.
#4. Postulate: If two lines are cut by a transversal such that corresponding angles are congruent, then the lines are parallel.
There are <em>3 </em><em />terms in the expression 5m, 2- mn + 4n + 7
Your answer is 3
Linear, because it would be a function something like y = .46 + .2x. Which is linear.
