The Quadratic Formula, x equals negative b plus or minus the square root of b squared minus 4 times a times c, all over 2 times
DedPeter [7]

Answer:

The correct option is  2 .

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is <u>  2 . </u>

     x=\dfrac{4\pm\sqrt{2}}{2}

Step-by-step explanation:

For a Quadratic Equation ax² + bx + c = 0

By Formula Method we get

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

So we have Quadratic Equation is 2x² - 8x + 7 = 0

On Comparing we get

a=2\\b=-8\\c=7

Substituting a , b, c values we get

x=\dfrac{-(-8)\pm\sqrt{(-8)^{2}-4(2)(7)}}{2(2)}\\\\x=\dfrac{8\pm\sqrt{64-56}}{4}\\\\x=\dfrac{8\pm\sqrt{8}}{4}\\\\x=\dfrac{8\pm2\sqrt{2}}{4}\\\\x=2(\dfrac{4\pm\sqrt{2}}{4})\\\\x=\dfrac{4\pm\sqrt{2}}{2}

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is <u>  2 . </u>

The slope-intercept form: y = mx + b

So we need to "solve" given equation for y

3.3x - 3y = 2.4           {subtracting 3.3x from both sides}

- 3y = 2.4 - 3.3x        {dividing both sides by (-3)}

  y = -0.8 + 1.1x

Therefore:

<h3>Slope:                         m = 1.1</h3><h3>y -intercept :               b = - 0.8</h3><h3>slope-intercept form:   y = 1.1x - 0.8</h3>
