If we want the final value F to double given 5% per year interest, F=2P then i=5.
Solving for n:
2P=P(1+0.05)^n
2=(1.05)^n
log(base 1.05)2=n
n=14.206=14.21 years

The system of linear equations that match with its graph and the solution is
- Number 3 with F has no solution.
- Number 4 with E has infinitely many solutions.
- Number 5 with B infinitely many solutions.
- Number 6 with C has one solution.
- Number 7 with D has no solution.
- Number 8 with A has one solution.
Making a graph of a system of linear equations is done by substituting the value x = 0 and the value y = 0 in an equation. After getting two points, draw a line through the two coordinates. But if the equation goes past the point (0 , 0) then take another value of x at random to get another point. Graph and solution
- The parallel lines will have no solution.
- Two intersecting lines will have one solution.
- Two coincide lines will have infinitely many solutions.

Answer:
Step-by-step explanation:
x=intercept is when the line intersect with the x axis when y=0
6: x intercept (1,0)
y intercept is when the line intersect with y axis at certain point or when x=0
y intercept (0.-24)
5: (0,-4) the y intercept
( 25,0) is the x intercept
21: (0,20) y intercept
(6,0) x intercept
22: (8,0) x intercept
(0 , 4) the y-intercept
