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.

Over [174]

Answer:

hello :

-1/4y-2 1/4y+1/2(4-2y) = -1/4y-2/4y+4/2 -2/2y

                                    = ( -1/4 -2/4 - 4/4)y +2

                                   = (-7/4)y + 2

Im not very sure how tot answer this i need help fast
Anna71 [15]
First see if there is a constant rate of change...

(344.8-346)/(2-0)=-0.6

(343-344.8)/(5-2)=-0.6

So the rate is constant which means this is just a line of the form y=mx+b

m=-0.6 and since we see that (0,346) we know the y-intercept, "b", is 346 so our line is:

y(x)=-0.6x+346

y(4)=343.6 ft

y(9)=340.6
