Answer:

Option C.

Step-by-step explanation:

$\sf\:x^{2}-3x+7=0$

Use the biquadratic formula.

$\sf\:\x=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 7}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-4\times 7}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-28}}{2}$

$\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{-19}}{2}$

$\sf\:x=\frac{3(+/-)\sqrt{19}}{2}$

Positive sign:

$\boxed{\sf\:x=\frac{3+\sqrt{19}}{2}}$

Negative sign:

$\boxed{\sf\:x=\frac{3-\sqrt{19}}{2}}$

Determine the equation of a line in standard form that represents alanas training progress. Her progress points corresponds to t

elixir [45]

Answer:

The equation of the line passing through the above points is:

$y=-\frac{1}{2}x+\frac{29}{2}$

Step-by-step explanation:

Given:

The two points are: $(x_1,y_1)=(1,14)\textrm{ and }(x_2,y_2)=(9,10)$

The equation of a line when two points are given is:

$y-y_1=\left (\frac{y_2-y_1}{x_2-x_1} \right )(x-x_1)$

Plug in all the values and simplify.

$y-14=\left (\frac{10-14}{9-1} \right )(x-1)\\y-14=\left (\frac{-4}{8} \right )(x-1)\\y-14=-\frac{1}{2}(x-1)\\y-14=-\frac{1}{2}x+\frac{1}{2}\\y=-\frac{1}{2}x+\frac{1}{2}+14\\\\\\y=-\frac{1}{2}x+\frac{29}{2}$

Therefore, the equation of the line passing through the above points is:

$y=-\frac{1}{2}x+\frac{29}{2}$
