Answer:

Step-by-step explanation:
As you can observe in the image attached, the line that best fits passes through point B and C. That means we can use those point to find the slope of such line.

Where
and 

So, the slope of the line that best fits is -11, approximately.
Now, we use the point-slope formula to find the equation.

Therefore, the line that best fits is
approximately.
Remember, when we estimate a line for some data on a scatterplot, we are calculating an approximation, that's why we also said "approximately", because the line is an approximation where the majority of point meet.

Answer:
6x ( 3x +4)
X =0 and x = 4/3 or x = 1 1/3
Step-by-step explanation:
Take the common factors out,
Here x is common to both equation and also 6 is common to both equation
So,
6x ( 3x + 4) = 0
So it can be solved by
X = 0 and x = 4/3
Answer:
x=3√5
Step-by-step explanation:
This is a right angle triangle
So the equation is
2²+x²=7²
x=√7²-2²
x=3√5
