Solve for x.
xenn [34]

Answer:

a \: \:  x =  \frac{ -1 ±  i\sqrt{139}}{14}

Explanation:

Since this is unfactorable, use the Quadratic Formula:

x =  -b ± \frac{ \sqrt{ {b}^{2} - 4ac}}{2a}

Now, take the information and input it:

-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\  \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ±  i\sqrt{139}}{14}

I am joyous to assist you anytime.

What equation in slope-intercept form represents the line that passes through the points
Mumz [18]
<h2>Answer:    y = - x + 1 </h2>

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

        For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:  

       The question gives us two points, (-3, 4) and (2, -1), from which we can find the slope and later the equation of the line.

 

<u>Finding the Slope</u>    

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)    

                                         =  (4 - (- 1)) ÷ ((-3) - 2)  

                                         =   - 1  

<u>Finding the Equation</u>

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:  

                                 ⇒  y - (-1) =  - 1 (x - 2)

                                        y + 1 = - (x - 2)

we could also transform this into the slope-intercept form ( y = mx + c) by making y the subject of the equation:  

                                   since  y + 1 = - (x - 2)                                                    

                                                ∴  y = - x + 1

<em>To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.</em>
