Answer: -16n-41

Step-by-step explanation:

first, distribute 2 through the parentheses:

2(-n-3)-7(5+2n) = -2n-6-7(5+2n)

second, distribute 7 through the parenthesis:

-2n-6-7(5+2n) = -2n-6-35-14n

Collect like terms:

-2n-6-35 and -16n-6-35

Calculate the difference:

-2n-6-35-14n = -16n-41

SOLUTION:

-16n-41

Answer:

left 1 unit
down 2 units

Step-by-step explanation:

The transformation g(x) = f(x -h) +k is a translation of f(x) to the right by h units and up k units.

1. h = -1, so the graph of g(x) is the graph of f(x) shifted left 1 unit. (blue)

2. k = -2, so the graph of g(x) is the graph of f(x) shifted down 2 units. (green)
