Dicriminant of x² – 49 = 0
Mama L [17]

Answer:

196

Step-by-step explanation:

The discriminant (Δ) is given by:

\Delta = b^2-4ac

Where the polynomial is in the form:

ax^2+bx+c=0

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

\Delta = 0^2-4(1)(-49) = -(-196) = 196

Thus, the discriminant of x² – 49 = 0 is 196.

Consider m = y2 - y1/ x2 - x1 . Which x1 and x2-values would determine that the line is vertical? Justify your answer
Y_Kistochka [10]

Answer:

x_2=x_1

Step-by-step explanation:

We were given the slope formula;

m=\frac{y_2-y_1}{x_2-x_1}

This line is vertical if the denominator is zero.

That is when x_2-x-1=0

This implies that;

x_2=x_1

Justification;

When x_2=x_1, then, the line passes through;

(x_1,y_1)  and (x_1,y_2)

The slope now become

m=\frac{y_2-y_1}{x_1-x_1}=\frac{y_2-y_1}{0}

The equation of the line is

y-y_1=\frac{y_2-y_1}{0}(x-x_1)

This implies that;

0(y-y_1)=(y_2-y_1)(x-x_1)

0=(y_2-y_1)(x-x_1)

\frac{0}{y_2-y_1}=(x-x_1)

0=(x-x_1)

x=x_1... This is the equation of a vertical line.
