Answer:

f(9) = 61

Step-by-step explanation:

You know f(x) = 8x - 11. So, to find f(9), you have to replace x with 9 on the other side.

f(9) = 8(9) - 11

You can solve this.

f(9) = 72 - 11

f(9) = 61

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.
