Answer:
Hey there!
The line is y=1/3x-1, and since the above is shaded it is y≥1/3x-1. (Note that this is a shaded line, so it is more than just >)
Hope this helps :)
First we want to find the amount that will be worth 20.7 after one year and 23.81 after two years
So I assume that
Y =p (1.15)^x
Where
Y 20.7
P ?
X 1 year
20.7=p (1.15)^1
Solve for p
P=20.7÷1.15
P=18
The answer is
Y=18 (1.15)^x
Standard form, hmm.
Multiplying an exponent is just adding, so let us do this.
Simplified, the answer should be
Y > 20
Hope this helps! Message back for an explanation:)
The answer is 24.5 because

so you add 5.5 from 19 to get the answer
