Question

what is wrong with this question?
solve for \(n\) \[-pn-40<70\]

Answer 1

i suppose it's that, by solving for n, you're not solving for the definition of n. you're solving for what's greater than n.

Answer 2

i could be out of the ballpark here tho

Answer 3

yeah for example i could say solve for \(n\): \(-3n-40<70\) and do it no problem

Answer 4

well p could be 0 or nonreal or undefined

Answer 5

that's what gives it a problem

Answer 6

er well being complex doesnt matter too much, but 0 or undefined

Answer 7

ok lets stipulate that we know \(p\) is real, and non zero

Answer 8

if p was 0 the inequality would still be true
-(0)n-40<70
-40<70

Answer 9

but you couldnt solve for n?

Answer 10

in that case you would have \((-\infty, \infty)\) as your solution
no problem there

Answer 11

guess it is not clear, which is why i saw this question earlier tonight

Answer 12

p dependence will cause varying regions of solutions.
