Answer:

n = 5, n = -7/2

Step-by-step explanation:

2n + 5 = l

n - 4 = w

A = l × w = 15

(2n + 5)(n-4) = 15

2n^2 - 8n + 5n - 20 = 15

2n^2 -3n - 35 = 0

(2n + 7)(n - 5) = 0

2n + 7 = 0 or n - 5 = 0

n = -7/2 or n = 5

The function f(x)={1/5}^x is translated up 4 units. Which equation represents the translated function

insens350 [35]

$f(x+n)\to\text{translation n units left}\\\\f(x-n)\to\text{translation n units right}\\\\f(x)+n\to\text{translation n units up}\\\\f(x)-n\to\text{translation n units down}\\\\\\f(x)=\left(\dfrac{1}{5}\right)^x\to f(x)+4=\left(\dfrac{1}{5}\right)^x+4\\\\Answer:\ g(x)=\left(\dfrac{1}{5}\right)^x+4$
