Answer:

Step-by-step explanation:


Let's find the discriminant of <span>x^2+9x+14=0. Here, a=1, b=9 and c=14.
The discriminant is b^2-4ac. Substituting the above numeric values,
9^2-4(1)(14) = 81-56 = 25
The sqrt of 25 is 5. Thus, your polynomial has two unequal, real roots.
Off the point example: If the discriminant were zero, your poly would have two real, equal roots.</span>

Answer:
r = 14
Step-by-step explanation:
Slope = 

Cross multiply,
-4 - r = -3*6
-4 - r = -18
-4 = - 18 + r
-4 + 18 = r
r = 14
