Create an equation to model an investment of 5000 dollars which increases by 15% each
year. Set up an equation to solve for how
long it would take to for the investment to
double. (You do not need to solve the
equation.)

Initial amount = 5000 $

Interest rate = 15 %

The amount increases exponentially.Then we get the following equation ,

It would double

= 10000

=> = 2

HOPE IT HELPS

PLEASE MARK ME BRAINLIEST ☺️

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
