let a,b,c,d be four integers (not necessarily distinct) in the set {1,2,3,4,5}. the no. of polynomials x^4+ax^3+bx^2+cx+d which
Eddi Din [679]
By either long or synthetic division, it's easy to show that

\dfrac{x^4+ax^3+bx^2+cx+d}{x+1}=x^3+(a-1)x^2+(-a+b+1)x+(a-b+c-1)-\dfrac{a-b+c-d-1}{x+1}

The quartic will be exactly divisible by x+1 when the numerator of the remainder term vanishes, or for those values of a,b,c,d such that

a-b+c-d-1=0

I'm not sure how to count the number of solutions (software tells me it should be 80), but hopefully this is a helpful push in the right direction.

Robert borrowed $750 from his parents. He promised to repay the loan by giving his parents at least $67 from his paycheck each w
Luda [366]

To answer this question we can propose the following equation:


d=750 -x(67)


Where:


x is the number of weeks elapsed.


d is the debt depending on the weeks.



Robert promised to pay at least $ 67 each week.


Therefore, after 5 weeks the debt of rober should be:


d\leq750-5*67

d\leq415


Then scenario A) is possible because 150.



After 6 weeks:


d\leq750-6*67


d\leq348

Then scenario B) is possible because 200.



After 7 weeks


d\leq750-7*67


d\leq281

Then scenario C) is possible because 250.



After 8 weeks

d\leq750-8*67

d\leq214

So scenario D) is NOT possible because 300>214



Finally the correct answer is option D.
