2(x-3) - 3(x+5) = 3(x-2)-7 2x - 6 - 3x + 15 = 3x - 6 - 7 2x - 6 + 6 - 3x +15 + 6 = 3x - 6 - 7 2x - 3x + 22 = 3x - 7 2x + 22 = -7 Now I am stuck

2(x-3) - 3(x+5) = 3(x-2) -7 (2x-6) - 3x+-15 = (3x-6) -7 -x-21 = 3x-13 -x-3x = -13+21 -4x = 8 x = 8/-4 x = -2 Is this correct?

sorry typo error above, question is, f(x): 700v^2 + 34500/v f'(x) : 700v^2 -34500/v^2 f"'(x) : ???

The question should be: f(x): 700v^2 + 34500/v f'(x) : 700v^2 -34500/v^2 f''(x) : ???

pls ignore the above question... to make it clearer for the question, it is... f(x): (700v^2 + 34500)/v f'(x) : (700v^2 -34500)/v^2 f''(x) : ???

i got the answer!! thank you!!!

nope, it's not a typo. the 5/2 is the power of 5 over 2. it is not 5 divide by 2. is my above answer correct?

yes it should be, F(v) : (600^3/2 + 20250)/v F'(v) : (300^3/2 - 20250)/v^2 F"(v) : (-150v^5/2 + 40500)/v^3 for F"(v), this is how i get: F'(v) : (300^3/2 - 20250)/v^2 F"(v) : ((300v^3/2 - 20250)' * v^2) - ((300v^3/2 - 20250) * (v^2)')/v^4 F"(v) : ((450v^1...

Ok but the power 5/2 is wrong? Should have been power 3/2? I keep on getting the answer 5/2.. I don't know which part of my working is wrong

I do not want the simplified answer by the way...I need the answer as an expression only

based on my question, i retyped... F(v) : (600v^3/2 + 20250)/v F'(v) : (300v^3/2 - 20250)/v^2 F"(v) : (-150v^5/2 + 40500)/v^3 Reiny, isn't your answer suppose to be f(x) = 600 v^(3/2) + 20250 v^-1, instead of f(x) = 600 v^(1/2) + 20250 v^-1 ?? 1/2 power a...

hi i think i know what you mean already. my answer for F"(v) (-150v^5/2 + 40500v)/v^4 i simplified further, it became (-150v(v^3/2 - 270))/v^4 cancel off the common factor v it became (-150(v^3/2 - 270))/v^3 Am i correct??

but there is no lHospitals rule in multivariable

yes i already got parts a and b i do not know how to do part c sorry i should have specified that in my post

Yes, I just copied the equation off of a different problem. Thank you for your help!

Please help! I'm so confused!

Anybody know what to do??

Whoops! it's suppose to be -3 squareroot 426!

D. 1.99(x-4) + 11.96 Because you can figure out the total cost of the four costing $2.99 (11.96), that has to be added to the other half of the equation. Simply multiplying 1.99 by x would include all apps instead of just the remaining (x-4).
