<h2>Solving Quadratic Equations with the Quadratic Formula</h2>

<h3>Answer:</h3>

$x = 3$ and $x = \frac{1}{2}\\$

<h3>Step-by-step Explanation: </h3>

Recall:

if we have a quadratic equation, $ax^2 +bx +c = 0$ , where $a$ , $b$ and $c$ are real numbers and $a \neq 0$ , $x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}$ .

Given:

$2x^2 -7x +3 = 0$

Solving for $x$ :

$x = \frac{-(-7) \pm \sqrt{(-7)^2 -4(2)(3)}}{2(2)} \\ x = \frac{-(-7) \pm \sqrt{49 -4(2)(3)}}{2(2)} \\ x = \frac{7 \pm \sqrt{49 -24}}{4} \\ x = \frac{7 \pm \sqrt{25}}{4} \\ x = \frac{7 \pm 5}{4}$

Solving with the positive value:

$x = \frac{7 +5}{4} \\ x = \frac{12}{4} \\ x = 3$

Solving with the negative value:

$x = \frac{7 -5}{4} \\ x = \frac{2}{4} \\ x = \frac{1}{2}$

The population of Columbus, Ohio in 2014 was about 823,000. The population of the United States was 319 million in 2014.

A coordinate grid is placed over a map and every unit represents 1 mi. The point at (3, 8) represents the location of the baseba

alexira [117]

The distance between 2 points $( x_{1}, y_{1})$ and $( x_{2}, y_{2})$ on the coordinate plane is $\sqrt{(x_{2}-x_{1})^2-(y_{2}-y_{1})^2}$
So the distance between the given points is $\sqrt{(7-3)^2+(-2-8})^2}= \sqrt{4^2+(-10)^2}= \sqrt{16+100}= \sqrt{116}=10.8$
As every unit is 1 mile, so the distance should be 10.8*1=10.8miles.

Hope this helps.

Find the mean of the following 2x-5y,5x+2y,8x+6y,x-y

White raven [17]

Answer: 4x + 0.5y

Step-by-step explanation:

Concept:

Here, we need to understand the idea of the mean (average).

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

**Disclaimer** I assume the question is asking for the arithmetic mean instead of geometric. If it was, then you can refer to my answers. If it was not, then you can point it out and I will redo the question.

Terms: 2x-5y, 5x+2y, 8x+6y, x-y

Number of terms: 4

[(2x-5y) + (5x+2y) + (8x+6y) + (x-y)] / 4

=[2x + 5x + 8x + x + 2y - 5y + 6y - y] / 4

=[16x + 2y] / 4

=4x + 0.5y

Hope this helps!! :)

Please let me know if you have any questions
