Question

An inequality is shown below:

−np − 4 ≤ 2(c − 3)

Which of the following solves for n?

n ≤ − the quantity 2 times c minus 2 all over p
n ≤ − the quantity 2 times c minus 10 all over p
n ≥ − the quantity 2 times c minus 2 all over p
n ≥ − the quantity 2 times c minus 10 all over p

Answer 1

You've got to isolate 'n', do you know how to do that?

Answer 2

Nu..

Answer 3

@pooja195

Can you help me please?

Answer 4

first isolate -np by adding 4 to both sides of the inequality

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

can you simplify that?

Answer 5

-4 + 4 = ?

Answer 6

0

Answer 7

ok
so we have -np + 0 <= 2(c - 3) + 4
the 0 disappears . so
-np <= 2(c - 3) + 4

now we divide both sides by -p to get n

NOte when you divide by a a negative with these inequalities the sign is flipped and so here it becomes >= .

Answer 8

p >= [2(c - 3) + 4] / -p

if you simplify that you'll get the correct choice

Answer 9

* that should be n >=

Answer 10

Ok.
