Solve. k + 6 > 19

Readme [11.4K]

Answer:

k > 13

Step-by-step explanation:

$k+6 > 19\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:k > 13\:\\ \:\mathrm{Interval\:Notation:}&\:\left(13,\:\infty \:\right)\end{bmatrix}$

$\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}$

$k+6-6 > 19-6$

$\mathrm{Simplify}$

$k > 13$

Thus, the answer is k > 13

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.

r-ruslan [8.4K]

Given:

The given quadratic equation is:

$12a^2+9a+7=0$

To find:

The solution for the given quadratic equation in simplest form by using the quadratic formula.

Solution:

Consider a quadratic equation is defined as $ax^2+bx+c=0$ , then the quadratic formula is:

$x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given quadratic equation is:

$12a^2+9a+7=0$

We have, $a=12,b=9,c=7$ . Using the quadratic formula, we get

$x=\dfrac{-(9)\pm \sqrt{(9)^2-4(12)(7)}}{2(12)}$

$x=\dfrac{-9\pm \sqrt{81-336}}{24}$

$x=\dfrac{-9\pm \sqrt{-255}}{24}$

$x=\dfrac{-9\pm i\sqrt{255}}{24}$ $[\because \sqrt{-a}=i\sqrt{a}]$

The solutions of the given equations are $x=\dfrac{-9-i\sqrt{255}}{24}$ and $x=\dfrac{-9+i\sqrt{255}}{24}$ .

Hence, the correct option is B.
