The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

The equation is given as:

x^2 + (1 - k).x+k-3 = 0

For an equation to have real root, then the following must be true:

[tex]b^2 \ge 4ac[/tex]

In x^2 + (1 - k).x+k-3 = 0, we have:

a = 1

b = 1 - k

c = k - 3

So, we have:

[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]

Evaluate

[tex]1 - 2k + k^2 \ge 4k - 12[/tex]

Collect like terms

[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]

[tex]k^2 - 6k + 13 \ge 0[/tex]

Using a graphing calculator, the value of k is all real numbers

Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

B is the correct answer

Answer:

k = 2

Step-by-step explanation:

3(-1) + k(5) = 7

-3 + 5k = 7

5k = 10

k = 2

The value of K in the equation 3x + Ky =7 is 2.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

Equation 3x + Ky =7.

And we have also given that (-1, 5) satisfies the equation.

That means,

(-1, 5) is a solution of the equation.

To find the value of K;

Substitute the value of x = -1 and y = 5

So,

3x + Ky =7,

3(-1) + K(5) =7

-3 + 5K = 7

5K = 10

K = 2

Therefore, the value of K is 2.

Answer:

y = - ( x + 2 )² + 14

Step-by-step explanation:

f(x) = ax² + bx + c

f(x) = a(x - h)² + k (where (h, k) are coordinates of the vertex.

h = - [tex]\frac{b}{2a}[/tex]

~~~~~~~~~~~~

f(x) = - x² - 4x + 10

a = - 1, b = - 4, c = 10

h = - [tex]\frac{-4}{2(-1)}[/tex] = - 2

k = - ( - 2)² - 4( - 2) + 10 = 14

(h, k) = ( - 2, 14 )
