Answer:
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. In this case, upon substitution, 25- 4*2*7 = -31 in which the roots are negative and iimaginary.

Answer:
The value of x = 4 if g(x) = 6
Step-by-step explanation:
Given the function
![g(x) = 3(x - 2)](https://tex.z-dn.net/?f=g%28x%29%20%3D%203%28x%20-%202%29)
as
![g(x) = 6](https://tex.z-dn.net/?f=g%28x%29%20%3D%206)
so putting the value of
in the function
![g(x) = 3(x - 2)](https://tex.z-dn.net/?f=g%28x%29%20%3D%203%28x%20-%202%29)
![6 = 3(x-2)](https://tex.z-dn.net/?f=6%20%3D%203%28x-2%29)
Switch sides and divide both sides by 3
![\frac{3\left(x-2\right)}{3}=\frac{6}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Cleft%28x-2%5Cright%29%7D%7B3%7D%3D%5Cfrac%7B6%7D%7B3%7D)
![x-2=2](https://tex.z-dn.net/?f=x-2%3D2)
![x=4](https://tex.z-dn.net/?f=x%3D4)
Therefore, the value of x = 4 if g(x) = 6
I found a similar problem to your problem here, which is shown in the attached picture. So, from the picture, we have to find the equation for the red line. All we have to do is find two points of the line. That would be: Point 1(2,0) and Point 2(-2,3). The general equation would be:
y - y₁ = (y₂-y₁)/(x₂ - x₁) * (x - x₁)
Substituting the coordinates to the equation,
y - 0 = (3-0)/(-2 - 2) * (x - 2)
y = -3(x -2)/4
Rearranging,
<em>4y = -3x + 6 or 4y + 3x = 6</em>
