Answer:
b. The first step in the equation solving is subtracting 8 from both sides of the equation.
Step-by-step explanation:
Here, the given quadratic equation is : 
Let us try and solve this given equation.
So, x = ± 5i
Hence, as we can see here, the first step in the equation solving is subtracting 8 from both sides of the equation.
Answer:
Both variables Can tell you the degree to which a linear relationship exists between two variables.
Step-by-step explanation:
Correlation and regression are two statistical concepts that are closely related and complement each other. They are powerful tools used in modern-day machine learning and artificial intelligence.
Correlation evaluates the linear relationship between two variables, using regression as a tool to assess the degree at which a dependant variable changes ( either increasing or decreasing ) based on the value of an independent variable.
The correlation coefficient is the degree of the linear relationship between two variables, ranging from zero ( for non-linear) to one ( for highly linear).

Explanation:
________________________________
Given: " x⁴ + 44 + 3.5 " ; and given: "x = 50" ;
we can plug in "50" for "x" ; and solve:
________________________________________
10⁴ + 44 + 3.5 ;
= 10,000 + 44 + 3.5 ;
= 10,047.5

Answer:
28
Step-by-step explanation:
x=blue
y=white
x+y=40
30x+20y=920
30(x+y=40) ; 30x+30y=1200___[1]
30x+20y=920 ; 30x+20y=920___[2]
[1]-[2] : 30x+30y-30x-20y=1200-920
10y=280
y=28
