Answer:
x=-13/3
y=13/4
Step-by-step explanation:
The equation of the scatter plot is (a) y = 100x + 2
<h3>How to determine the equation of the scatterplot?</h3>
The line of best fit of the scatter plot passes through the points
(x,y) = (0,2) and (1,102)
The equation is then calculated as:
![y = \frac{y_2 -y_1}{x_2 -x_1}(x - x_1) + y_1](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2%20-x_1%7D%28x%20-%20x_1%29%20%2B%20y_1)
Substitute known values in the above equation
![y = \frac{102 -2}{2-1}(x - 0) + 2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B102%20-2%7D%7B2-1%7D%28x%20-%200%29%20%2B%202)
Evaluate the expression on the right-hand side
y = 100x + 2
Hence, the equation of the scatter plot is (a) y = 100x + 2

Answer:
1st problem:
-1, 2i, -2i
Set the function equal to 0 and divide for x
0=x^3+x^2+4x+4
Subtract 4 from both sides leaving you with
-4=x^3+x^2+4x
divide both sides by four
-4÷4= -1
That is how you get -1
you now have -1=x^2+x^3+x
Solve for x buy finding the square roots of x^2, x^3 and subtracting x from both sides and you get 2i, -2i
Your answer to number one is -1, 2i, -2i
Second problem:
Find the LCD to be able to add these first
The LCD of (x-4)/x^2-2x is
x(x-2)
That is the first side done
The second side's LCD is (x+2)(x-2)
Now you can add the two together
x(x-2)+(x+2)(x-2)=
Your answer in fraction form is
(x+4)/x(x+2)
Answer:
same slope, different intercepts (parallel lines essentially)
