Answer:

If a quadratic has nonreal roots, then the discriminant .  b^2 - 4ac

Plug in the values for b, a, and c into this equation to get .  k^2-4 *12*27 < 0

Rearrange to get .  k^2 < *12*27

Now factorize 4*12*27 and solve to get - 36 < k<26

Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB
Snezhnost [94]

Answer:

Step-by-step explanation:

Slope: \frac{y_2-y_1}{x_2-x_1} when the given points are (x_1,y_1) and (x_2,y_2)

Plug in A(8,3) and B(4,8)

=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}

Therefore, the slope of AB is -\frac{5}{4}.

I hope this helps!
