2000 x 1.03^5 = $2318.55
i think this question is about compound interest so my answer should be correct i hope it helps

I'll solve for y
xy+(4(20))>x-5y(2+9-7)
xy+4(20)>x-5y(2+9-7)
xy+4(20)>x-5y(4)
xy+4(20)>x-20y
xy+80>x-20y
xy+20y+80>x
y(x+20)>-80+x
y>(-80+x)/(x+20)
The midpoint of the line having the endpoints

and

is

basically average them
so given that the line has the endpoints of (-3,7) and (9,-2)
x₁=-3
y₁=7
x₂=9
y₂=-2
so the midpoint can be found by doing



the midpoint is
