Last year, Amy opened an investment account with $6400. At the end of the year, the amount in the account had increased by 21.5%. How much is this increase in dollars? How much money was in her account at the end of last year?

it's both, now can you answer my most recent question?

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

(x+3)(x+7)
