Answer 4

Well, what would be your first step?

Answer 5

You want n on its own, you have -np-4, what can you do to move everything but n?

Answer 6

ok here is what i got

-np - 4 <= 2(c - 3)

-np - 4 <= 2c - 6

-np - 4 + 4 <= 2c - 6 + 4

-np <= 2c - 10

-np/p <= (2c - 10)/p

-n <= (2c - 10)/p

but I don't have a negaitive sign. is that because i gotta divide by -p?

Answer 7

if I do then i got

n >= -(2c - 10)/p which is D

Answer 8

soo it would be D?

Answer 11

@KaylaIsBae h mm -6 + 4 = -10?

Answer 12

\(\bf -np-4\le 2(c-3)
\\ \quad \\
-np\le 2c-6+4\implies -np\le 2c-2
\\ \quad \\
-n\le \cfrac{2c-2}{p}\impliedby \textit{division by a positive value, no sign change}
\\ \quad \\
n{\color{red}{ \ge}}-1\cdot \cfrac{2c-2}{p}\implies n\ge \cfrac{-2c+2}{p}\impliedby \textit{by a negative value, sign change}\)
