How to solve and why the answer is (A)

Amanda [17]

$\dfrac{1}{2}x^2+mx=5\\
\dfrac{1}{2}x^2+mx-5=0\\\\
\Delta=m^2-4\cdot\dfrac{1}{2}\cdot(-5)=m^2+10\\
\sqrt{\Delta}=\sqrt{m^2+10}\\\\
x=\dfrac{-m\pm\sqrt{m^2+10}}{2\cdot\dfrac{1}{2}}=-m\pm\sqrt{m^2+10}$

Rewrite the following equation in slope-intercept form.<br><br> 3x − 11y = 19

Law Incorporation [45]

Answer:

y = 3/11(x) - 19/11

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

$3x-11y-3x=19-3x$
$-11y=-3x+19$

Step 2: Divide both sides by -11.

$-11y/-11=(-3x+19)/-11$
$y=\frac{3}{11}x-\frac{19}{11}$

Therefore, the answer is y = 3/11(x) - 19/11.
