The discriminant of the equation x^2 - 4x + 4 = 0 shows there will be solution(s).
Alex787 [66]

Answer:

one real

Answer: 1

Step-by-step explanation:

Givens

a = 1

b = -4

c = 4

Discriminate

Discriminate = sqrt(b^2 - 4*a*c)

Discriminate  = sqrt(  (-4)^2 - 4 * (1)(4) )

Discriminate = sqrt ( 16 - 16)

Discriminate = sqrt(0)

Discriminate = 0

That means the 1 real root is -  b / 2a = 4/(2*1) = - -2 = 2

A half of a class and a half of a student got A on a test. If yet another student got an A, then two-thirds of the class would h
svlad2 [7]

Answer:

6 students.

Step-by-step explanation:

let the number of students in class be<em> x</em>

Since Half of the class represents half of the students, therefore

Number of student who got A in test = \frac{x}{2}

Now if one more student got A in test then the number of students who got A in test will be \frac{x}{2} +1

Now according to equation,

\frac{2x}{3} = \frac{x}{2} +1

\frac{2x}{3} - \frac{x}{2} = 1

Further solving

\frac{4x-3x}{6} = 1

x = 6

Hence the total number of students in class is 6.
