Answer: y+3 = 4( x + 1)
Step-by-step explanation:
The equation in point slope form is given as :
y - = m ( x -
) , where m is the slope
slope = 4
point given : (-1,-3)
Using the formula :
y - = m ( x -
)
and substituting the value , we have
y - (-3) = 4 (x -{-1} )
y+3 = 4( x + 1)
Answer:
It takes 75 years for the investment to quadruple in value
Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
4% simple interest per year, so I = 0.04.
Quadruple:
t when T = 4P.
The interest earned is:
Now we find the time.
