4:5 because a quadrilateral has 4 sides and a pentagon has 5 sides
        
             
        
        
        
The form which should be used when you know the slope of a line and one of the points on the line is: d. point-slope form.
<h3>What is the 
point-slope form?</h3>
The point-slope form can be defined as an equation which is used when the slope of a line and one of the points on this line is known.
Mathematically, the point-slope form of a line is given by:
y - y₁ = m(x - x₁)
<u>Where:</u>
In conclusion, you should use the point-slope form when you know the slope of a line and one of the points on the line is given.

Answer:
Take the coefficient of ''n'', divide it by 2, and raise it to the second power;



 
        
             
        
        
        
For this case, the first thing we must do is define a variable.
 We have then:
 x: total sales for the week
 We now write the equation that models the problem.
 We have then:
 p (x) = 0.035x + 300
 Answer:
 a function, p (x), which can be used to determine his pay for the week is:
 p (x) = 0.035x + 300
        
             
        
        
        
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
Option A:

The slopes are not the same.
Option B:

The slopes are the same so the lines are parallel.
Option C:

The slopes are not the same.
Option D:

The slopes are the same so the lines are parallel.
Answer:
The parallel lines are: Option B and Option D
