If x= 6 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the
equation?
o the discriminant is 0.
o the discriminant is 6.
o the discriminant is positive.
o the discriminant is negative.

The discriminant is 0.

Step-by-step explanation:

we know that

In a quadratic equation of the form

The discriminant is equal to

If D=0 -----> The equation has only one real solution

If D>0 ----> The equation has two real solutions

If D<0 ----> The equation has complex solutions

In this problem

If the equation has only one intercept (x=6)

then

The equation has only one real solution

therefore

The discriminant is 0.

yes. we do proportions in probabilities.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
