What is the quotient? x-1)7x^2-3x-9

7x + 4.

Step-by-step explanation:

       7x + 4 <Quotient.

x - 1)7x^2 - 3x - 9

       7x^2 -7x

                 4x - 9

                 4x - 4

                        -5 <Remainder

part a- option 1 is exponential and increases 130% per year. option 2 increases $300 per year and it's linear.

part b- f(n)=1000+300n option 2

f(n)=1000(1.30)^n option 1

part c- f(20)=1000+300(20)

f(20)=1000+6000

f(20)=7,000 after 20 years for option 1

f(20)=1000(1.30)^20

f(20)=1000(190.04)

f(20)=190,040 after 20 years for option 2

we can see that there would be a significant difference in belinda's investment if she uses option 2 over option 1. there is a huge difference of 190,040 - 7,000 = 183,040 dollars.
