$59,000

Step-by-step explanation:

Simple interest : A=P(1+R T)

A = Accrued

P = Principal amount

R = rate

T = time

P = 50,000

r = 2% or 0.02

t = 21-12 = 9 yrs

A = $ 50,000(1+ (0.02 x 9)

A = $ 50,000 x 1.18

A = $ 59,000

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
